Chlorine Stabilizer is a granular, totally soluble product that prevents free chlorine residual loss due to sunlight. Without Stabilizer, chlorine quickly dissipates and consumption increases. This product is formulated to reduce maintenance costs and chlorine consumption. It is intended only for outdoor, chlorinated pools. The key ingredient of this product is cyanuric acid.
1 lb per 4,000 gallons of water will provide initial stabilizer level of 30 ppm.
