Natural Chemistry liquid stabilizer & conditioner is used for stabilizing chlorine from UV sunlight consumption. Unlike regular dry Cyanuric acid with a very acidic pH of 2.8 & a dissolve time ofup to 7 days, Natural Chemistry Instant pool water conditioner is not an acid, it's a salt. Stabilizer won't protect chlorine from UV loss until it's completely dissolved, & while dissolving, dry Cyanuric acid can cause damage to the pool surface or circulation system. Since Natural Chemistry liquid stabilizer dissolves instantly, it begins to protect chlorine instantly & with no risk of damaging your swimming pool. Chlorine will last 6-10 times longer in pool water that is properly conditioned & stabilized with Instant pool water conditioner. Dosage: 1 gallonper 10,000 gallon of pool water.
