Natural Chemistry's Instant Pool Water Conditioner® is used for stabilizing chlorine from UV sunlight loss. Regular cyanuric acid with a pH of 2.8 is very acidic and it takes from 4 to 7 days to dissolve. This can cause damage to the pool surface or circulation system, depending on the method of application. Natural Chemistry's Instant Pool Water Conditioner® is not an acid (it's a salt) and has a pool friendly pH, so it will not damage pool surfaces or equipment.
