Cyanuric acid, often abbreviated as CYA, is a chemical compound used to stabilize chlorine in swimming pools. It acts as a protectant, shielding chlorine from rapid degradation caused by ultraviolet (UV) rays from the sun. Without it, chlorine would dissipate quickly, rendering it ineffective in sanitizing the pool water. For example, a pool exposed to direct sunlight without a sufficient level of CYA may require significantly more chlorine to maintain proper sanitation levels.
The presence of cyanuric acid is crucial for maintaining consistent sanitation and preventing algae growth. By extending the lifespan of chlorine, it reduces the frequency and amount of chlorine needed, leading to cost savings and minimizing potential skin and eye irritation associated with high chlorine concentrations. Historically, the use of stabilizers like CYA has revolutionized pool maintenance, shifting from constant chlorine additions to a more balanced and sustainable approach.
