Note: Using MPS in your pool or spa water comes with a few benefits. For instance, MPS breaks down the ammonia in your pool water faster than chlorine would and helps in balancing the levels (especially when your CYA levels are high). It also help to reduce CC, which is what causes those harsh smelling chlorine odors (if you have a salt system it will do this automatically). Please note that for a short period of time your CC level’s will be reportedly higher than usual. This is completely normal when adding MPS to your swimming pool. It's particularly popular in bromine spas/hot tubs because it works really well in hot water. There’s also a couple of negatives when it comes to MPS. Although it's good at removing CC, it’s not as good at fighting off algae outbreaks. Overall, TFP is not anti-MPS, but chorine is the recommendation for most cases.
