What is the minimum accepted level of cyanuric acid in pool water?

Cyanuric acid acts as a stabilizer for chlorine in pool water, helping to protect it from degradation by sunlight. The minimum accepted level is crucial because it ensures that chlorine remains effective in killing bacteria and controlling algae growth. A concentration of 30 ppm is widely recognized as the baseline necessary for optimal chlorine performance in outdoor pools.

Lower levels of cyanuric acid may lead to rapid loss of chlorine due to UV degradation, which can compromise the overall sanitation of the pool. This is why maintaining this minimum level is key to ensuring a safe and healthy swimming environment. Additionally, levels above this threshold can also be managed to prevent excessive build-up but maintaining at least 30 ppm is essential for effective disinfection.
