Significance of Use
Chlorine is the most commonly used water disinfectant used by
homeowners, hotels, and commercial businesses. In swimming pools,
spas, and similar applications, cyanuric acid helps to stabilize chlorine
and prevent its breakdown, especially in sunlight. Frequent testing of
both cyanuric acid and pH helps to minimize chlorine consumption.
