What Are Proper Cyanuric Acid Stabilizer Levels in a Pool?
Where cyanuric acid stabilizer is used, it is recommended to have your pool routinely stabilized in a range between 25 ppm and 50 ppm. A stabilizer level below 50 ppm combined with a pH below 7.0 or FAC above 3.0 ppm can accelerate membrane wear and shorten its service life. Check with your local/state/provincial regulations.
Cyanuric acid stabilizer levels should generally be maintained between 25 and 50 ppm to protect chlorine from UV degradation while maintaining effective sanitation.
Poolside by CGT guidelines highlight the importance of stabilizer control to support effective chlorine performance.
