Cynuric Acid in Pools: Ideal Levels & Importance for Chlorine Stability

Maximum level: 100 ppm

Cyanuric acid is a stabilizer that helps protect chlorine from being broken down by sunlight. It is important to maintain a minimum level of cyanuric acid in pool water to ensure that the chlorine is effective. However, too much cyanuric acid can cause the water to become cloudy and difficult to sanitize.
