Natural Chemistry's Pool Perfect is a proprietary blend of natural ingredients that break down; suntan oils, cosmetics, body oils, bather wastes, and other non-living organic contaminants. Pool Perfect works with all sanitizers and continually keeps filters cleaner longer. Pool Perfect also prevents waterline rings and black water line rings. Just add to the water- no scrubbing necessary! Water stays silky soft and odor free. Pool Perfect contains our SMARTzyme technology. SMARTZyme technology wastes no time breaking down non-living organic materials. A small amount of Natural Chemistry's enzymes can treat large amounts of water due to their ability to bind to non-living organic contaminants and reduce them to smaller and smaller parts, breaking them down to their original components such as carbon dioxide and water.
