Cyanuric Acid - 100 Lb - 2790-B

Chlorine added to swimming pool water will dissipate with time. To slow the burn off of your chlorine by the sun’s rays, you need to add a chemical known as a ‘Stabilizer’ to your pool water. Cyanuric Acid will act as a pool chlorine stabilizer when properly applied. Think of it like sunblock for your pool, partially surrounding the chlorine on a molecular level to protect the chlorine and prevent it from being rapidly dissipated by the sun. The Stabilizer level of swimming pool water must be maintained at 30-50 ppm. While the Stabilizer level is important, it is typically only tested at the beginning of the swimming season when a pool is opened.
