Cyanuric acid (CYA) is a chemical compound added to swimming pool water to stabilize chlorine. It acts as a shield, protecting chlorine from rapid degradation caused by ultraviolet (UV) rays from the sun. Without adequate CYA, chlorine dissipates quickly, becoming ineffective at sanitizing the pool. Insufficient CYA levels necessitate higher chlorine usage to maintain a safe and sanitary swimming environment.
Maintaining an appropriate CYA level is crucial for effective pool sanitation and cost-effectiveness. By minimizing chlorine loss, CYA reduces the frequency and quantity of chlorine additions, leading to long-term savings on pool maintenance. Historically, the understanding of CYA’s role in pool chemistry has evolved, leading to more precise recommendations for its proper usage and levels to ensure optimal water quality and bather safety.
