What is the maximum cyanuric acid level before it is considered a violation?

Cyanuric acid is commonly used in pool maintenance as a stabilizer to help protect chlorine from being broken down by ultraviolet (UV) rays from the sun. However, it is essential to monitor its concentration in swimming pools, as excessively high levels can lead to greater challenges in maintaining water quality and can affect disinfection efficacy.

The maximum allowable level of cyanuric acid before it is considered a violation is set to ensure safe swimming conditions while maximizing the effectiveness of chlorine. A level of 70 ppm has been established as a threshold that balances these concerns. Going beyond this level can compromise the balance of water chemistry, leading to potential risks such as chlorination issues and algae growth.

The levels above this threshold, such as 80 ppm, are not just inappropriate for effective sanitation but are also deemed unsafe for swimmers. Levels below 70 ppm, like 50 ppm and 60 ppm, are generally acceptable, signifying that while cyanuric acid helps in stabilizing chlorine, there should be a cap to prevent adverse outcomes.
