Stabilizer (CYA) protects chlorine from UV rays, but it does not evaporate. Repeated tablet use can push CYA so high that chlorine stops working effectively.

What pool owners should know

A useful operating window is 30–50 ppm CYA for traditional pools and 60–80 ppm for many saltwater pools.
At 100+ ppm, the required free chlorine rises sharply. High CYA makes it nearly impossible to maintain a sanitary pool without massive chlorine additions.
There is no dependable chemical additive that removes high CYA; safe, partial dilution with fresh water is the standard solution.
Consistent monitoring of CYA levels dictates when to switch from stabilized tablets to liquid chlorine.

Rivera Pool Care takeaway: If high chlorine still leaves the water cloudy, stop adding shock blindly. We test CYA accurately and choose a safe strategy.
