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 black waterline 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.
