Pool Water Chemistry Explained
Cyanuric acid (CYA) helps protect chlorine from sunlight—but when levels get too high, it can quietly make your pool unsafe. Learn safe CYA ranges, hidden risks, and how proper testing keeps your pool protected.
If your pool has chlorine but still isn’t sanitary, cyanuric acid may be the reason. Learn how CYA binds chlorine, why most of it becomes inactive, and how to maintain the correct FC/CYA balance.
Pool test strips may show “normal” chlorine levels even when water is unsafe. Learn why test strips fail at high cyanuric acid levels and how to get accurate pool water results.
Balancing cyanuric acid and chlorine is essential for safe pool water—but impossible without accurate testing. Learn why digital photometers are the only reliable solution.
