What is the minimum recommended level of cyanuric acid in ppm?

Cyanuric acid acts as a stabilizer for chlorine in swimming pools, protecting it from the degrading effects of sunlight. The minimum recommended level of cyanuric acid in a pool is typically set at 30 ppm. This level ensures that chlorine remains effective in maintaining water sanitation without being overly depleted by UV exposure.

If the cyanuric acid concentration is too low, the chlorine can quickly dissipate, leading to insufficient sanitation and potential water quality issues. Conversely, levels that are significantly higher can impede chlorine's effectiveness as well. Therefore, maintaining the cyanuric acid level around 30 ppm strikes a balance, allowing for effective chlorine retention while minimizing the risk of any negative impacts on water quality and swimmer comfort.
