Stabilized to ensure effectiveness

Stabilized to ensure effectiveness

Stabilized chlorine has been treated with cyanuric acid, which acts like sunscreen to protect against high heat and UV rays that can burn the chemical and render it ineffective. Stabilized chlorine is more effective over a longer period of time, and is perfect for use in especially hot climates or in pools that receive full sun for the majority of the day
Use with floaters and chemical feeders

Use with floaters and chemical feeders

These slow-dissolving chlorine tablets have optimum hardness to ensure you get the correct dosage for your pool. They dissolve completely and can be used in floaters, skimmers, or automatic chemical feeders
For clean, fresh water

For clean, fresh water

Tri-Chlor contains more chlorine by weight than dihydrate Di-Chlor, but either will work to neutralize viruses and bacteria, leaving you with clear water that’s safe for you and your family
