How to Choose the Right Above Ground Pool Filter System

Finding the perfect combination of swimming pool pump and filter is essential in creating an effective filtration system for your above ground pool.  Below we have included some, easy to follow, steps to make sure you are choosing the right pump/filter combination for your pool.

The purpose of choosing the correct combination is to avoid any problems that could potentially create premature malfunctions, ineffective filtration or safety hazards. The pump and filtration system of an above ground pool sits fairly close to the pool, creating a shorter travel time for your water to pass through your filter and back to your pool. Before deciding what horsepower you need, it’s important to take the following factors into consideration:

  • General Pool Size – small, medium, or large
  • Filter Type – sand or cartridge
  • Cleaner Type – suction side, pressure side, or robotic

Finding the correct sizes that work well together will greatly affect the way your pool will perform. Above ground pool pumps range from 1/2-1½ HP and a pump with too much horsepower will create excess water movement.  If you have a smaller pool, this could pose as a safety hazard, creating unpredictable water flow.

Above Ground Pools First, figure out what size range your pool falls into. Filter sizes are relative to the pool size. A smaller pool will require a smaller filter and a larger pool will require a larger filter.
Filter Type Second, find out which filter type you’d prefer. There are two main types for above ground pools: sand and cartridge. Each has their own benefits and filter to different microns.
Pool Cleaner Type Third, know what type of cleaner you’ll be using.  Suction side, pressure side, and robotic cleaners effectively clean an above ground pool but are powered differently.
  • Suction Side Cleaners – Suction side cleaners are affordable and most commonly used. Attaching to the suction side of the plumbing system, the pool pump powers the cleaner, drawing in dirt and debris. Large debris or high volumes of debris, such as leaves, can clog pipes leading to the filtration system.
  • Pressure Side Cleaners – Pressure side cleaners conveniently capture their own debris and also help to circulate water and pool chemicals. This is convenient because uncirculated water in “dead zones” will encourage the growth of algae. Pressure side cleaners attach to the return port, and a vacuum is created to pick up dirt and debris.
  • Robotic Cleaners – Robotic cleaners run independent of your pool’s pump and filter, collecting debris in a self-contained fine mesh bag.  They are the most efficient out of all pool cleaners because they do not clean the same area twice.
Things to Remember:
  • Choosing a higher horsepower will increase water flow movement and water turnover.
  • A higher horsepower will change the performance of your cleaner, increasing speed and suction. Note: This change could potentially harm your above ground pool liner.
  • When using a sand filter, anything above 1.5HP will create excessive water movement and push sand into your pool.
  • For a standard above ground swimming pool, a 1HP pump is sufficient to sanitize your water and run cleaners.
For your convenience, we offer filter and pool pump combinations. Take the guesswork out of choosing the correct swimming pool pump and filter by selecting one of our many packages. We offer a selection of pump and filter combinations to properly fit your above ground pool.

    We have an 18 x 34 above ground pool. What is the best size of sand filter system to purchase for this pool?

    • PoolSupplyWorld

      Hi Wendy, thank you for your excellent question. For a pool size of 20′ x 40′, which is similar to yours, we would recommend a sand filter size of 30-36 and 1HP or 1-1/2HP pump. Please let us know if we can be of any further assistance.

  • April Castillo

    I have a 9x18x52 above ground intex pool. The pump is a 1500GPM, I would like to upgrade to a sand filter pump… any suggestions?

    • PoolSupplyWorld

      Hi April, generally, for standard above ground pools, a Waterway Above Ground Filter System TWM-30 Sand without Trap will work well. This pump and filter combo is designed to circulate pools up to 12,000 gallons in the recommended 8-10 hour turnover time. Please let us know if we can be of any further assistance.

  • Jeff

    I am considering replacing both my 1 HP pump and D.E. filter Hayward model EC-75. I am looking at the Intelliflo #011018 and Clean and Clear cc150. The pool size is 9,000g in ground with a suction style Hayward navigator cleaner. Is this a good combination?



  • Arnie Abrams

    Hello, We have a Doughboy above ground pool with a deep end (partially in-ground-3 ft. shallow end to 7.5 ft deep end). It is approx. 16 x 34. I seem to go through Hayward pumps every couple of years, and just found out that I am due for a new pump again (the impeller is shot and the base is corroded from water). I have always had 1-HP pumps. Can you recommend a heavier duty pump that will resist corrosion and has a high-duty impeller that can withstand the elements? Additionally, should I go with a 1.5-HP pump, since the shallow end of the pool never seems to get clean? Also, can you recommend a mid-range automatic pool cleaner that will do a good job? I currently use the manual method with an attachment to the suction side of the pump. It works OK, but I would rather just leave it and come back in a couple of hours to a clean pool. Thanks in advance!

    • PoolSupplyWorld

      Hi Arnie, if you are looking for a more durable pump, the Pentair Dynamo 1HP Dual Speed Above Ground Pool Pump without Cord – 11.0/2.9A 115V is a sturdy, water-resistant pump for use with above ground pools. It includes self-priming, for a longer lifespan, as well as reinforced fiberglass and structural integrity. However, if you live in an area with increased rain, we highly recommend ensuring your pump is protected, either with a pump cover or shelter.

      If you’d prefer a 1-1/2HP pump, the Pentair Dynamo 1-1/2HP Dual Speed Above Ground Pool Pump without Cord – 16.4/4.4A 115V sports the same durability but boasts more power. If your current pool cleaner is not reaching across your entire pool, it may be a sign that you need a stronger pump, and a 1-1/2HP pump will definitely give it the necessary water pressure for optimal mobility. Please note, for the best water flow rate, a 1-1/2HP pump requires 1-1/2″ piping.

      Dual speed pumps, such as those mentioned above, will allow you to run your pump at full capacity when operating your pool cleaner, but reduce it to a lower speed for regular filtration, which will help save on energy costs while also prolonging the life of your pump. Neither pump comes with a cord, and the proper cord would be the 3 Foot Twist Lock Cord, which is part number 155234. We do not currently stock this cord, but would be happy to work with you on a special order.

      As for an automatic pool cleaner option, a good suction-side cleaner choice is the Polaris 65 Turbo Turtle Above Ground Pressure Side Automatic Pool Cleaner, which is designed for above ground pools and features a 24′ hose. Because your pool is 34′ long, depending on the location of your skimmer, you may need to purchase one or two extension hose(s), which are the Polaris 65/Turbo Turtle Pool Cleaner 7′ Sweep Hose Complete.

      It also might be best to take a look at an automatic robotic cleaner if you’re having difficulties cleaning your entire pool. The Aquabot Pool Rover Hybrid Above Ground Robotic Pool Cleaner is ideal for pools up to 36′ long, and should easily navigate your entire above ground pool. It includes an internal filtration system that is entirely separate from your existing filter, using a 34-quart capacity filter bag for debris collection and features a 1-hour cleaning cycle.

      If you have any further questions on the best pump and cleaner set up for your above ground pool, or if you would like help in placing a special order for a cord, please feel free to contact us for immediate assistance.

    24 ft round 54 in depth what size pump and filter should i use

    • PoolSupplyWorld

      Hi Greg, the appropriately sized pump and filter for your 24′ round, 54″ deep above ground pool will depend on the size of your pool’s plumbing. 1-1/2″ plumbing can handle a maximum of 42 GPM while 2″ plumbing can accommodate up to 73 GPM and 2-1/2″ as much as 120 GPM. That said, an ideal combination option for your pool is either the Pentair Clean & Clear 75 Sq’ Cartridge Filter System with 1HP OptiFlo Above Ground Pool Pump or the Pentair Clean & Clear 100 Sq’ Cartridge Filter System with 1HP OptiFlo Above Ground Pool Pump.

      The only difference between the two systems is the size of their cartridge filter, with the 100 square foot filter providing more filtration capacity, which will mean less frequent cleaning. The 100 square foot filter can also handle flow rates up to 100 GPM, while the 75 square foot filter can accommodate flow rates of up to 75 GPM.

      If you have further questions about the best pump and filter system for your above ground pool, please feel free to contact us for immediate assistance.

  • KJenness

    We have a 18 x 36 aboveground pool with a deep end. We currently have a 1.5 Hayward pump with a cartridge filter that is about 7 years old. Thinking about replacing the filter because we had trouble keeping a clear pool the last few years. Called where we purchased the pool and were told it is not our cartridge filter we just needed to keep phosphates in the water to keep algae away? We live in Michigan, added algacides all last summer and rarely had a crystal clear pool. Do we need a new filter system, or just need better instruction on chemicals. If a new filter is needed which is better DE or a sand filter? Confused in Michigan

    • PoolSupplyWorld

      Hi K, if your pool filter is properly sized for your pool and the cartridge element is clean and has no damage or excessive wear, it is unlikely the filter is the cause of your cloudy pool and more likely the chemical balance of your pool is off. Contrary to what you were told, you do not want to keep phosphates in your water. Phosphates are the food source for algae, so the higher the phosphate level in your pool, the more likely you are to have algae. Phosphate levels should be as close to zero as possible.

      We suggest using a Natural Chemistry Phosphate Test Kit to attain the phosphate level of your pool, and Natural Chemistry PHOSfree 2 L if levels are high. To learn more about phosphates, check out our blog: What are Phosphates and How Do They Affect Your Swimming Pool?

      Once phosphates are under control, an algaecide should kill any existing algae. If after treating your pool with algaecide you experience cloudy water, this is likely dead algae pores that are too microscopic for your filter to process. Using a clarifier will group these small particles together to form larger particles that can be vacuumed or netted from your pool or filtered through your filtration system. If your phosphate levels are in check and algae is not a problem, we would recommend either using a Taylor Complete High Range Pool and Spa Water Test Kit to test the chemical balance of your pool, or taking a water sample to a local pool shop. Proper pool water balance is essential for a clean pool.

      If after testing and treating your water you decide you still want to purchase a new filter, a D.E. filter, such as the Hayward Pro-Grid Vertical Grid D.E. 24 sq. ft. In Ground Pool Filter, would be a better choice than a sand filter if finer filtration is what you’re after. A D.E. filter is capable of filtering particles as small as three to five microns, while a sand filter can only filter down to 20 to 25 microns. Comparatively, a cartridge filter has the ability to filter to as small as five to 10 microns.

      If your cartridge filter element appears worn or damaged, replacing it may be all that is needed to remedy the issue. If this is the case, or if you have further questions or would like assistance in purchasing a new filter, please give us a call so one of our friendly, knowledgeable customer service representatives can assist you in finding what you need.

  • Jay Phillips

    Installing a 27′ by 54″ above ground pool. Planning to use Hayward Matrix 1.5, 2spd with a Pentair Clean and Clear RP 100 and standard offline chlorine feeder. No heater or water features. Intending to hard plumb main drain & skimmer with 2″ PVC, sweep elbows, etc. My questions. Is there any real benefit to plumbing with 2″ vs 1.5″ PVC? Would this allow me to use a smaller more efficient pump? (1 HP 2spd.) Is the 100sq/ft cartridge sufficient. Is there a benefit to the 150 or 200 sq/ft cartridge? I’m installing and cost is not an issue. Thanks. Jay

    • PoolSupplyWorld

      Hi Jay, the main benefit of 2″ plumbing over 1-1/2″ plumbing is that it allows for higher water flow rates. 1-1/2″ plumbing can only accommodate flow rates of up to 42 GPM while 2″ plumbing can accommodate up to 73 GPM. Using 2″ plumbing over 1-1/2″ would not impact the ability to use a smaller, more efficient pump.

      For your 27′ round, 54″ deep above ground pool, which is approximately 19,000 gallons, you should not need a filter larger than the Pentair Clean and Clear RP 100. In fact, this 100 square foot filter is larger than you need. It is always good to oversize your pool filter to prevent wear and provide the convenience of less frequent cleanings, but the CCRP 100 can turn over as much as 48,000 gallons in eight hours. A smaller cartridge filter, such as the Pentair Clean and Clear CC75 Cartridge 75 sq. ft. In Ground Pool Filter might be better suited for your 19,000 gallon pool.

      Similarly, if you have no plans to incorporate a suction-side or pressure-side pool cleaner or other water feature, you should not need a pump as strong as 1-1/2 HP or dual-speeds. For just water circulation, a single-speed 1 HP pump, such as the Pentair Dynamo 1HP Single-Speed Above-Ground Pool Pump with 3′ Standard Cord – 12.0A 115V, should be sufficient. We also offer filter/pump combinations, and the Pentair Clean & Clear 75 Sq’ Cartridge Filter System with 1HP OptiFlo Above Ground Pool Pump is an ideal option for your pool size.

      If you have further questions, please feel free to contact us for immediate assistance.

    • PoolSupplyWorld

      Hi Angela, you can definitely replace your pump with a Hayward pump, however, we will need to know your pool’s gallon capacity, as well as the size and type of your filter before we can make the appropriate pump recommendation. If you can please provide us with a more detailed idea of your pool configuration, we will be happy to recommend a suitable replacement pump.

  • susie Utley

    I am looking to replace a filtering system on a 18 x 33 foot above ground pool. I currently use a sand filter.

  • margaret

    hello i have a 22″ oval above ground pool and i am looking for the nest filter for it ? what would u recommend i get?The one that came with the pool doesnt do anything. thank u margaret

    • PoolSupplyWorld

      Hi Margaret, for your 22′ above ground pool, if it is a cartridge filter you are looking for, we would recommend the Pentair Clean and Clear CC50 Cartridge 50 sq. ft. In Ground Pool Filter. This filter will provide enough square footage to easily turn over your entire pool in the recommended eight to 10 hours, and its size will also help extend the time between necessary cartridge cleanings. If you have any further questions, or if this is not the type of filter you are looking for, please give us a call for additional assistance.

  • Scott

    I was looking to buy a new sand filter for my 24′ above ground. It holds 13.5K gallons. I am thinking of buying a filter good for 21,000 gallons instead of a bare bones minimum filter. What would you recommend for brand and model and what 120v motor would you sugges to go with it?

    • PoolSupplyWorld

      Hi Scott, for your 13,500 gallon above ground pool, we would recommend the Pentair Sand Dollar SD40 Sand Filter System with 1HP Dynamo Above Ground Pool Pump. This sand filter is large enough to provide the proper filtration for your pool and extend the time between necessary backwashings, and the 1HP Pentair Dynamo pump will meet your voltage and water flow requirements. If you have further questions about the best pump and filter combo for your pool, please feel free to give us a call for immediate assistance.

  • Monica

    We moved to a house that has an 18 x 33 above ground pool (I believe it is 42 deep). The current pump (which I just replaced) is a 1 hp. I just don’t think their is enough suction to vacuum the bottom well and I don’t see the water “swirling” around like my neighbors pool when the pump is running. Is this a big enough pump for this pool?

    • PoolSupplyWorld

      Hi Monica, a 1 HP above ground pool pump is usually adequate for an above ground pool your size, and above ground pool pumps tend not to exceed more than 1-1/2 HP for safety reasons. To ensure the best circulation, please make sure to regularly clean your filter and to empty your pump’s skimmer basket completely. Doing so will improve water flow for better performance.

      You should also make sure there isn’t a blockage or air within the system, both of which could cause issues with your vacuum. There could also be an issue with the cleaner itself. Make sure there’s no debris clogging the underside or hoses, and also check your hoses and hose connections to make sure there aren’t any holes or leaks. You may also simply need to increase the pressure to the cleaner. If you have any further questions, please feel free to contact us for immediate assistance.

    My Hayward PowerFlo LX appears to have gone out. The pool is less than 10 years old but should I replace the filter as well? 21 foot round 48 deep

  • Traci Beach

    My pool is 15 x 30 oval. What is the best size and type of filter system for my pool?

    • PoolSupplyWorld

      Hi Traci, the pump and filter system we would recommend for your 15′ x 30′ above ground pool is the Pentair Clean & Clear 75 Sq’ Cartridge Filter System with 1HP OptiFlo Above Ground Pool Pump. Cartridge filters are easier to maintain and have better filtration abilities than sand, and this particular filter is sized large enough to extend the time between cleanings while providing comprehensive filtration. The 1HP pump will easily be able to turn your entire pool over in the recommended time, and will be powerful enough to operate a suction-side pool cleaner, as well. If you have any further questions, please feel free to contact us for immediate assistance.

  • Maryann

    I currently have a 1.5 HP sand filter for an 18′ above ground pool. the filter keep throwing sand back into the pool. Is the pump too strong for the pool? The filter and pump are more than 11 years old. Are cartrigde filters efficient? I was thinking abount changing over. Can you recommend a filter?

  • Bryan

    I currently have a 24′ X 16′ above ground pool with 1 1/2” piping. I have a Hayward S166T sand filter and bought a Hayward Power Flo LX 1.5HP pump. Is 1.5HP too powerful for the S166T filter. Should I buy a 1HP filter instead? What do you recommend? Thanks

    • PoolSupplyWorld

      Hi Bryan, your sand filter has a maximum flow rate of 35 GPM, and the maximum flow rate that your 1-1/2″ piping will allow is 42 GPM. In order for the Hayward Power Flo LX 1.5HP pump to work, your piping configuration will need to be installed at 50′ of head to ensure the flow rate is below 35 GPM.

      Because of this, it’s recommended to use a slightly smaller pump, such as a 1 HP, to ensure that your filter will be able to withstand the water pressure without being damaged. If you’re looking for a replacement 1 HP pump, the Hayward PowerFlo II 1HP Above-Ground Pool Pump with 3′ Twist-Lock Cord – 115V is from the same series as your original pump and offers the same 1-1/2″ piping requirements and voltage. If you have any further questions, please feel free to contact us for immediate assistance.

  • Andrea

    We bought a Lomart 27′ x52″ pool about 8 years. last summer we bought a new Hayward 1.5hp sand filter. Now upon opening the pool we discovered a leak and rust on skimmer return wall. We don’t know extent of damage yet but just knowing it is there has me concerned about wall integrity and 18k gallons of water near my house and most importantly…my kids in it. This is 2nd Lomart pool in 10 years (liner tore..pulled wall in..they replaced). Im getting very discouraged. Thought we bought a good pool. What is a good pool…for NH weather, if that matters? Does size effect longevity? Sounds like the hayward filter is pretty standard and we should at least be able to reuse that, correct? Thank you so much for your opinion.

  • Maria

    I have a 24′ X 52″ round above ground pool. The filter system is old and needs to be replaced. It is a Hayward Perflex D.E. EC-75 system. I want to replace it with another D.E. system. What is the best model or size for my pool?

    • PoolSupplyWorld

      Hi Maria, your existing filter has a maximum flow rate of 100GPM, which means it can filter your 15,000 gallon pool in well under eight hours. If you’re looking for a similar filter, the Hayward Pro-Grid Vertical Grid D.E. 36 sq. ft. In Ground Pool Filter, which accommodates a maximum flow rate of 72 GPM, and the Sta-Rite System 3 Grid D.E. 37 sq. ft. In Ground Pool Filter, which works optimally at 56 GPM, are both great systems.

      Please note, however, that plumbing modifications will need to be made, as these two cleaners work best with 2″ PVC piping, while the Perflex uses 1-1/2″ piping. Reducers will easily fit the 2″ PVC unions of the Pro-Grid and can be purchased at a local home goods store. Please let us know if we can be of further assistance.

  • chris

    I have a 24×16 above ground pool with a older Hayward filter with a1.5 hp pump.. there does not seem to be a lot of suction at the skimmer. the pump was for a smaller round pool I am wondering if maybe the pump is bad.

    • PoolSupplyWorld

      Hi Chris, a 1-1/2 HP pump should create more than enough suction for your 24’ x 16’ above ground pool. Check your plumbing and remove any obstructions or blockages that may be causing low flow. Also, check for any points where air may be entering the system. If your plumbing is fine, we recommend contacting your pump’s manufacturer for additional troubleshooting steps. You can also have a qualified pool technician come out and assess your existing set up. Please let us know if we can be of further assistance.

  • Tom S.

    I have a 27 ft round 16500 gallons above ground pool, 1-1/2 inch piping, D.E. filter EC-45 (45 GPM) with Hayward Power-Flo 1-1/2 HP 15Amp pump (16 yrs old), and Intex Krystal Clear salt water generator. I need to replace the pump. Which of the following pumps would you recommend for my pool: Hayward Power-Flo Matrix 2-speed (SP15922 or 15932), or Hayward Power-Flo LX (SP1580 or 1580X15) ? Should I go with 1 HP or 1-1/2 HP pump?

    • PoolSupplyWorld

      Hi Tom, usually a 1HP will work just fine for a 16,500 gallon above ground pool. A two-speed is definitely more energy efficient, since you can run the low speed for circulation and switch to high speed when running an automatic cleaner. If you don’t have any water features, you can go with the Hayward PowerFlo Matrix 1HP Above Ground Pool Pump with 3’ Twist-Lock Cord- 115V. Please let us know if we can be of further assistance.

  • Brenda

    I have a 24ft x 52″ Pro Series Pool the pump and filter are attached to the side of the pool. The pump has gone out on me 3 times in app. 5 months. What pump/filter system combination would you suggest would be the easiest/most effective to install with this type of pool? Thank you so much for your response.

    • PoolSupplyWorld

      Hi Brenda, you might be interested in the Pentair Sand Dollar SD60 Sand Filter System with 1-1/2HP Dynamo Above Ground Pool Pump with 250lbs of Sand and will be able to turn over your pool in well under the recommended eight hours. It works best with 1-1/2″ piping, and it’s 6-position multi-port valve is easy to use and read. This unit also includes a 1-1/2 HP Dynamo pump, which features a highly durable design of thermoplastic to resist corrosion, and its motor is constructed for an extended lifespan.

      However, because you have a Pro Series pool, special adapters may be required, and you will need to contact the manufacturer of your pool to ensure compatibility. Please let us know if we can be of any further assistance.

  • Scott

  • Ana

    I have an Intex 18′ x 48″ above-ground pool. I think the pump that was supplied with the pool is not working like it should. I’ve checked the hoses, but it’s just not filtering like it should. I would like to upgrade to something better – with a cartridge filter system.

  • Kara

    • PoolSupplyWorld

      Hi Kara, for your 18′ round Intex pool, we would recommend the Waterway Above Ground Filter System TWM-30-S Sand with Trap. This system features a 16″ sand filter and 1/2 HP pump, both of which will be ideally sized for your pool. You may need an adapter to install this system to your Intex pool, since Intex pools are designed very uniquely, and for this you will need to contact Intex directly. If you have further questions, please feel free to contact us for immediate assistance.

    Just purchased a 18′x48″ above ground pool with a catridge filter. I’m wondering if I might need to upgrade to a sand filter for a cleaner pool? Thanks for you help. Larry

    • PoolSupplyWorld

      Hi Larry, you shouldn’t need to switch to a sand filter in order to get cleaner pool water as cartridge filters generally have better filtration ability than sand. You may, however, need to switch filter sizes if your pool water isn’t being filtered properly. If you can let us know the filter you currently have (make and model), we’ll be happy to recommend one that fits your pool size more appropriately. Please feel free to contact us for immediate assistance.

    HI, I have an 18′ x 33′ x 54″ above ground oval pool. This pool is roughly 12 years old, with a 1-year old liner, and (I don’t know how old!!) a 2.5 HP pump (that’s what it says on pump housing, at least) and cartridge filtration system. I am having an issue getting completely rid of what my pool store says is dead algae (had an issue w/algae earlier this Spring from lawn chemical), and am wondering if the cartridges (I clean/swap out at each vacuum) are filtered out. I appreciate any assistance in this.

  • Rich Hawkins

    Hi, we have a 24′ round above ground and are running a Matrix Power Flo 1 1/2 HP pump with a C750 Hayward cartridge filter. Is this a good combination? We are also using Baquacil instead of chlorine and it seems like the fight for a crystal clear pool is never ending. Thanks :)

    My husband just noticed that our pump/filter system is shutting down. I know nothing other than it’s a sand filter. We have a 24′ round/48″ deep pool. What is the best option for replacing the pump/filter? cartridge? 1 or 1 1/2 HP? (I know all research states for us to get 1 HP since our pool is up to 24′, but I want to be sure that it’s enough since our pool is right on the border (up to 24′) of what everyone recommends. ALso, what can we expect to pay for a new pump/filter system? THANK YOU!!!

      Hi Kim, One HP will be fine for your pool and will save you money on your electric bill as well! There are a lot of different options as far as pricing. I will have someone from our sales team get in touch with you regarding pricing and options. Thanks!

    • PoolSupplyWorld

      Hi Kim, Do you have the model number from your current pump?

    We just purchased a filter/pump combination from you that should be here tomorrow, after talking with other people,, we are not sure we ordered the right size. We ordered the Sandpro 75 3/4 hp. Our pool is a intex 24 x 52 pool. Will this work for our pool?

    • PoolSupplyWorld

      Hi Tammy, That filter/pump combo will work fine for your system and comes with the adapters needed to hook it to an Intex pool!

  • Joann

    How much motor power is recommended for a 12000 gallon above ground pool? We have a new Hayward 3/4hp which was recommended by our pool guy – we used to have 2hp – in comparison – the water looks like it’s not being moved.

    • PoolSupplyWorld

      Hi Joann, 3/4 HP is plenty of power for circulation of your size pool. Really, it’s a matter of what you like. If you prefer more circulation, you can definitely use a larger pump. The advantage of using the 3/4 HP pump is that it will use significantly less energy than your old 2 HP. Let me know if you have any questions. Thanks! -Christian

    I have a 10 thousand gallon above ground pool. I am moving the filter 50 feet from pool. I’d like to use a 1 1/2 HP pump with a 14 inch sand filter. I’m using 1 1/2 inch section 40 grade flex from pool to filter then regular PVC to make connections. Is this a good choice? Pool is level with my deck.

    • PoolSupplyWorld

      Hi Michael, Do you have the model numbers of both your pump and filter? Let me know and I’ll make sure that you’ll get enough circulation with that set-up. Thanks! -Christian

  • Bill Baker

    I have an 18 ft above ground pool using a ec30 Haywood DE filter with a 1 hp motor—Someone gave me a EC 65 or 75 with a gold plated 1 ½ Hp motor, Should I keep what I’m using or use the EC 65/75 to clean pool faster?

  • Randy

    I have a 24′ 52″high above ground pool, I have a Magnetek 1 1/2 hp 2 speed pump with a 150 sq ft cartridge filter. The motor quit working , so I would like to go to a smaller 1 hp 2 speed motor. Would that be ok with my current cartridge filter? I am looking at a hayward E2190 pump. Do you recommend any others?

  • Janet

    My pool
    l is 18×33 will the 1HP do the job ?Thankx

    • Dylan (PoolSupplyWorld)

      A 1HP pump would be sufficiently sized to circulate the water in that size of pool. Now we would also want to know what size and media filter it is that you are using? It is important to match up the pump size to the filter size to make sure the pump doesn’t “overpower” it. Feel free to let us know on here or contact one of our sales reps directly at 800-772-0467!

      • Janet

        Hayward 40lb maybe it is a big one will check under the deck for sure tho soon .oh here is the model Hayward PR series S210T

        • Dylan (PoolSupplyWorld)

          Sounds like you have right about a 20″ filter tank which would be an appropriate size to use with a 1HP above ground pool pump.

    I have an 18 X 34 above ground pool with a Hayward sand filter Model S210T and a 1.5 HP Hayward Power flo pump. The pump is dying and needs to be replaced. I’m not sure if that’s the correct size pump to go with my filter. Can you help? Thanks!

  • Lynn Bradford

    Hi there – I love that you have this site to answer questions!
    I have a Morada above ground pool – 24 x 54 x 9, with a 120 sq ft cartridge filter/1.5 HP pump. I’m over this cartridge filter stuff – cleaning it, and even then, I’ve gotten algae 2 summers in a row now, quite significantly. Chlorine is good, I vacuum, it gets used….and all while my neighbor, with a bigger pool, has no issues – with a sand filter.
    What sand filter would you recommend for our pool? We have not much debris from trees, with the exception of some cottonwood floaties.

  • Char

    Please help! I have a 21×52 above ground w/cartridge filter my pump is fine it is a Hayward,however the filter that holds the cartridge is cracked AGAIN this is my 2nd one in 3 years GRRR…the last one i ordered online generic version maybe that’s why???? Now i cannot close my pool until i purchase a new one my question is should i switch to a sand filter since i have had sooo many issues w/cartridge? I need one that is compatible w/pump PLEASE HELP running out of $$$$$$$$!


    • Dylan (PoolSupplyWorld)

      If the filter does keep cracking that is a sign that the pump is either too strong for the filter size, or that the pressure is being allowed to build to a very high level. Once the pressure on a filter rises roughly 10 psi above the starting level, then it is a sign that the filter cartridge needs to be cleaned off. If the cartridge is several years old then it will slowly start to become too compacted and will require replacing.

      The first question would be what model pump and filter is it that you currently have? Any model numbers and brand names would be helpful, a picture would be great also. Once we determine what we have we can decide if it’s the correct size or not and then recommend a new cartridge or a new sand filter.

      Feel free to give us a call directly at 800-772-0467 if you needed quick assistance selecting a new unit.

  • Judy Kharuddin

    We have an above ground pool that is 15′ L x 8′ W x 4′ D and we need to buy a pump and filter for it as well as a vacuum, I think. I’m a little confused, is the vacuum attached to the filter/pump system, or is it a separate thing? Is a 1 horsepower enough for the size pool we have? Also, when buying a filter/pump system, do we need to look for the PSI or is this an automatic number with the size of horsepower we get when we buy the filter/pump?

    • Dylan (PoolSupplyWorld)

      Hello Judy,

      Above ground filter and pump systems do come as a package, which makes sizing them fairly easy. A 1 horsepower pump would be an appropriate size pump for your pool, and the next question would be whether you wanted a sand or cartridge filter. The PSI number would not be important when deciding which system to purchase. Later, once the system is installed, the PSI number will tell you when the filter is dirty and needs cleaning.

      As for an automatic pool cleaner (vacuum), it will depend on what kind of style cleaner you want to go with. There are robotic pool cleaners which just plug into a standard wall outlet, and would be entirely separate of your filter/pump system. Next, you have suction side pool cleaners which would attach to your skimmer, and whenever the pump is on the cleaner will move around the pool and suck up debris. Finally, you have pressure side cleaners, these attach to the return water jet and when the pump is on and running it will collect debris in an attached bag.

      I might suggest giving one of our sales reps a call at 800-772-0467 to help pick out a good filter/pump system, as well as find a good vacuum (cleaner) for your pool. Thanks!

  • Mark Adkins

    I have a 33 foot round pool above ground with the Pentair Sand Dollar SD60 filter system that has had an alge problem for the three years I have had it. I have the water checked regularly all levels show good and clean it regularly the pool place that test the water for me doesn’t know why the problem is reoccurring they recommend putting a inground pump on it because of the pools size . Any thoughts before I spend even more money doing this? If this is what it needs would it need another skimmer and return plumbed in for it to work their guess is the water doesn’t have enough movement allowing the alge to grow.

    • Dylan (PoolSupplyWorld)

      To begin with, would you have the numbers from your water testing? Especially the chlorine and the cyanuric acid levels. If you haven’t done so already, I would recommend replacing the sand in the filter and essentially starting fresh. Really clean out the inside of the tank as well to ensure there’s no algae left over.

      The water in the pool needs to turn over at the minimum one time per day, what model pump do you have? And how many hours out of the day are you running it? You can try running the pump for longer during the day to turn the water over more, and get more filtration.

      As long as it’s not a huge jump up in horsepower (which it shouldn’t be) then the existing skimmer and plumbing should be just fine to handle the water flow.


      • Mark Adkins

        The chlorine levels average 3 ppm cyanuric acid average 28 ppm. Not sure myself but they tell me this is an acceptable level ? I changed the sand this year and cleaned the tank with bleach. I also run the pump 24/7 . The first year I had it I used chlorine the second I used baqucel with no change in alge controll went back to chlorine this past summer so I did a total clean out and started fresh. The pump say it is 1 and a half hourse power. Any advice would be greatly appreciated.

        • Dylan (PoolSupplyWorld)

          For an above ground pool and your filter system, your not going to want to go over the 1-1/2 HP pump that you currently have. You could try raising the cyanuric acid level as your 28 ppm is a bit on the low side. The cyanuric acid acts as a sunscreen for your chlorine, and helps with the effectiveness of it. Around 50 ppm might be a more ideal level for you. How do you add chlorine to your pool currently? Chlorine tablets should generally have cyanuric acid already built into it.

          Do you get a lot of leaves, grass, or other material falling into the pool? If so, this may raise your phosphate level which would encourage algae growth. I would get your phosphate level tested as well and then try a phosphate remover such as the Natural Chemistry Pool Perfect + Phosfree.

          In summary, I don’t believe going with a larger pump would be beneficial. Raising the cyanuric acid level and lowering the phosphate levels should help to reduce algae growth. Thanks!

  • Elizabeth

    I have a 15ft 52′ round AGP. I am trying to determine which would be the best sand filter for this pool. Any suggestions?

  • http://batman-news.com Mary

    Hello, we installed a 24 ft x 48 inches above ground round pool last summer and had nothing but problems with pumps and filters. It had been a used pool so we initially started out with a cartridge and it turned green and had algea build up. Then the pump broke so my father brought us a different pump and a sand filter, which we used brand new sand. We still had problems keeping the pool clear of algea even though we were constantly getting the numbers checked at the local pool store and everything was fine. We are looking for a new system completely and are unsure which will be the better decision between a DE, cartridge, or a sand filter. Please help with any recomendations.
    Thank you

    • Dylan (PoolSupplyWorld)

      Hello Mary,

      All three of the filter styles that you mentioned will have their own advantages and disadvantages. Let me briefly touch on each one.

      -DE Filter; will provide the clearest filtration as it filters to the finest micron levels. Does require the DE being replaced each time it is backwashed. DE filters generally aren’t used for above ground pool setups, but it is possible.

      -Sand Filter; simplest filter to maintain as all it requires is backwashing, no replacement of sand needed. The filtration quality will be the poorest of the three choices. Sand filters are popular for above ground pools due to the easy maintenance and relatively cheap pricing.

      -Cartridge Filter: most environmental friendly option as it does not require backwashing, or wasting, water out of the pool. For cleaning you simply remove the cartridge and hose it down to wash it off. Filtration quality will be in the middle of the options. Also a filter style that is popular with above ground pools.

      Ultimately for a recommendation, I am more of a fan of cartridge filters and would generally recommend cartridge first and sand second. If you are running into issues with algae, it may require running the pump for a longer duration of the day, and more frequent cleaning of the filter. If you still happened to have a chemical level readout I would be happy to take a look at the numbers and give you my thoughts. The chlorine levels, CYA, phosphate, and pH levels would be especially helpful.


      • http://batman-news.com Mary

        Thank you for the response. We are currently looking at two different cartridge filter/pumps but aren’t sure which to go with, Do you think you could help? We like the Hayward xstream 1hp and also the hayward easy-clear 1hp. I know the hayward xstream is the better but it looks to be a lot of power and im not sure if we need that or if the easy clear will be sufficient.

        • http://PoolSupplyWorld.com/ Whitney (PoolSupplyWorld)

          The XStream and Easy-Clear are definitely great filters. Both would definitely work for your pool, but the major difference you will see is in the longevity of the filter. The XStream’s larger size ensures an equal distribution of dirt and debris throughout the filter which keeps this filter running for a longer life span. I would recommend it over the Easy-Clear.

          Thank you!

  • sally

    I have a 16 X 32 oval pool with a doughboy sand filter with 1.5 pump. Have to vacuum daily due to greyish stuff on the bottom of the pool. Filter runs most of the day but does not get rid of the stuff on the floor of the pool. It drives my husband crazy he wants to replace the whole filter system?????

    • Dylan (PoolSupplyWorld)

      To try and eliminate this build up on the bottom of the pool I would suggest taking a few steps:
      1) Backwash/replace the sand in your filter.
      2) Run the pump the entire day, or two.
      3) Apply a shock treatment to the pool (2-3 bags).
      4) Take a brush to the bottom and walls of the pool to stir up debris.
      5) At the end of the pump running for 24-48 hours, backwash again to clean out debris that may have collected.

      This is a basic algae control regimen that you can attempt to get a hold of the situation. And then afterwards ensure your chlorine levels remain at the proper levels, otherwise algae may find its way into the pool again.

      As for switching system, a cartridge filter does have slightly finer filtration than a sand filter, and may be a bit better at collecting debris that passes through.

  • Angie

    I have a 27′ x 52″ round pool and a Hayward 1 hp 2pd pump. I’m looking for the biggest cartridge filter for this set-up, but I can’t find anything over 150 sf. Any suggestions? Also, do I need to go with a Hayward filter to be compatible with the Hayward pump? Thanks!

    • http://PoolSupplyWorld.com/ Whitney (PoolSupplyWorld)

      Thank you for visiting! You don’t have to go with a Hayward filter, but many people do like to stay within the same brand of equipment. A couple great options for your pool could be the Pentair Clean and Clear 200 or the Jandy CS250. Both of these will provide the large filter capacity that you are looking for.

  • proudcrazyazzcracker

    I have a 18×34 Above Ground Oval shaped pool. The sand filter and pump that came with the pool when I bought the house seems to be in need of replacement. I am considering changning to a cartridge filter, and a new pump but have no idea which one to select. I would like to change to cartridge for ease of cleaning, and use. I am trying to avoid the sand filter backwash, and now the filter seems to be releasing a lot of sand back into the pool. Any sugestions

  • Sunshine

    If I have a 28′ round pool, looking for a replacement sand filter and pump, what would you recommend? 19″ sand filter w/ 1 HP motor? Pentair Sand dollar, Hayward Pro series, Pro Above?

  • PoolSupplyWorld

    Hi Joyce, for your 24′ round above ground pool, we would recommend either the Hayward S180T or S220T sand filter rather than the S166T, as they will pair better with your 1 HP pump and be better equipped to handle your pool’s capacity. The larger S220T filter will also help extend time between backwashings. Please let us know if we can be of any further assistance.

  • PoolSupplyWorld

    Hi Dan, the Hayward Pro-Grid Vertical Grid D.E. 48 sq. ft. In Ground Pool Filter is a great choice to replace your current 36 square foot D.E. filter, and will be able to turnover your entire 21,000 gallon pool in the recommended eight to ten hours. It can accommodate a maximum flow rate of 96 GPM, and utilizes 2″ plumbing for installation.

    There are multiple valves that are compatible with the Pro-Grid DE Filter, including the Hayward 1-1/2″ Reverse Multiport Valve, which is a six position vari-flo valve, and the Hayward Pro Grid 2″ SKT Selecta-Flo Multiport DE Valve, which is a four position selectra-flo valve. Depending on your piping configuration, either of these valves will work well. If you have any further questions, please feel free to contact us for immediate assistance.

    Hi Susie, thank you for your interest in a new filtration system for your 18′ x 33′ above ground swimming pool. A member of our sales team will contact you shortly to help you find the system best suited for your pool.

  • PoolSupplyWorld

    Hi Ryan, you shouldn’t have to replace your pool filter if you’re replacing your pool pump unless the filter is showing signs of wear, as well. However, you’ll want to make sure that your new pool pump is sized to fit your existing filter, as pool filters are designed to work with a certain GPM maximum. Going over that maximum could potentially damage the filter or cause it to wear down much faster than it normally would.

    If you are replacing the pump in a pump-filter combination, it’s important to ensure that your replacement pump will fit your equipment pad, as well as the connections between the pump and the filter. So we can better assist you in finding a replacement pump, please contact us directly, and a customer care agent will be happy to recommend a suitable option.

  • PoolSupplyWorld

    Hi Maryann, it’s common to see some sand blow back into your pool after backwashing, but if you are seeing consistent sand intrusion during your filtration cycle, it’s likely due to a damaged part within the filter that would need to be replaced. The only way to find out what it is would be to empty the filter completely and examine it.

    In terms of your pool pump, 1-1/2 HP is more than is necessary for a pool of your size. If it has worked to this point and is in fine shape, it is not necessary to downsize, but doing so could save on energy consumption.

    Switching to a cartridge filter is something we highly recommend. Cartridge filters are easier to maintain than sand, and they do a better job of filtering your pool water. The Pentair Clean and Clear CC75 Cartridge 75 sq. ft. In Ground Pool Filter would be an excellent option for your pool. It can accommodate flow rates of up to 75 GPM, so you will want to be sure your pool pump will not overpower it as a flow rate too high for a filter can damage the filter. This could be what you experienced with your sand filter.

    If you want to also replace your pool pump while replacing your filter, we have a variety of great options, including the Pentair Clean & Clear 75 Sq’ Cartridge Filter System with 1HP OptiFlo Above Ground Pool Pump, which includes the aforementioned Clean and Clear cartridge filter. If you have further questions about the best filter system for your pool, please feel free to give us a call for immediate assistance.

    Hi Andrea, the longevity of any pool is affected by many factors such as the quality of parts, water chemistry, and maintenance. Our above ground pools from Sharkline are made with galvanized steel walls that are inserted into a thick, heavy steel or durable resin bottom rail. High quality parts paired with proper installation will extend the life of your pool. A pool made with resin parts will be more resistant to rust than a pool made completely of steel.

    One way to prevent corrosion and rust is to apply a wall foam behind your liner. This will provide a barrier to prevent algae growth and rust build-up. Another important factor is water chemistry. Keeping your water balanced and maintaining your pool will protect your pool equipment and parts from damage. You can use AquaChek Select Test Strips to consistently monitor your water chemistry.

    As far as your Hayward filter, it sounds like a standard part and you should be able reuse it as long as it’s not damaged. If you have further questions about a new pool or pool equipment, please feel free to contact us directly for immediate assistance.

  • PoolSupplyWorld

    Hi Lisa, a 1 HP pump is ideal for an above ground pool, which doesn’t typically require high horsepower ratings. As long your filter is large enough and your piping can accommodate 1 HP, a 1 HP pump will work well with your pool. Please let us know if we can be of any further assistance.

  • PoolSupplyWorld

    Hi Ana, for your 18′ round Intex pool, we would recommend the Waterway Above Ground Filter System TWM-30 Cartridge with Trap. This system features a 25 square foot cartridge filter and 1/8 HP pump that can deliver a flow rate up to 1800 GPH, which should be ideal for your 7,600 gallon pool. You may need an adapter to install this system to your Intex pool, since it is not designed by Intex, and for this you will need to contact Intex directly. If you have further questions, please feel free to contact us for immediate assistance.

  • PoolSupplyWorld

    Hi Tim, if the cartridge elements in your filter are requiring more frequent cleaning, are not coming clean or have rips, tears or wear, it may be time to replace them. That said, to assist in removing the dead algae from your pool, you can use a product like Super Floc Clarifier, which helps clump the dead algae together so it sinks to the bottom of your pool and is easier to either net or vacuum out.

    If you do need new cartridges for your filter, please provide us with the brand and model of your filter and we’ll be happy to recommend the proper replacement(s). If you have further questions or would like immediate assistance, please feel free to contact us directly.

  • PoolSupplyWorld

    Hi Janice, the Intelliflo VF is a great pump that automatically adjusts its flow to accommodate your pool size and will work with any type of filter. If you’re looking for a different filter system, we recommend a cartridge system like the Pentair Clean and Clear CC100, which has 100 square feet of filter area and will turn over your water in less than four hours.

    Cartridge filters are easy to clean, don’t require backwashing or recharging, and can filter down to 5 microns. Please feel free to contact us directly and we’ll be more than happy to help you find the right filter/pump combination for your pool.

  • PoolSupplyWorld

    Hi Kerry, installing an above ground pool can vary from builder to builder. It will also depend on if you decide to contract your entire build or just part of it. The best thing to do is call around to local builders for a better idea. Please let us know if we can be of further assistance.

  • PoolSupplyWorld

    Hi Helen, above ground pools can use salt chlorinators, but if your pool is metal, it’s advised against it, only because salt can quickly corrode any metal areas. Most above ground pools are made of resin plastic, and nowadays, certain chlorinators are designed specifically for above ground pools. Please feel free to let us know if you have any further questions.

  • Kim

    I currently have a 1.5 HP jacuzzi pump. It’s 6 years old and just started smoking this morning…yikes! I did some research and the 1.5 Dynamo keeps coming up. Being almost $300, I feel that we can get one a little cheaper, but not sacrifice quality or longevity. OR an I an idiot and completely mistaken? Thanks for your help!

  • PoolSupplyWorld

    Hi Bill,
    Either one of those pumps will do the trick for you though I would recommend sticking with the 1 HP. The 1 HP is plenty of power for your pool and will use less energy than a 1.5 HP. Let me know if you have any questions! -Christian

  • PoolSupplyWorld

    Hi Randy,
    You will lose a little bit of turnover by downsizing the pump but other than that you shouldn’t have any issues. With a cartridge filter there is no need to backwash so losing some horsepower is not a problem. The pump you are looking at will be fine. Let me know if you have any other questions! -Christian
