Enzyme Water Cleaner & Phosphate Remover, 1 Quart

CV-700 is a unique, stabilized enzyme formula with a phosphate remover blended in. It effectively breaks down and removes non-living organics (bather waste) and oils from water, while also reacting with phosphates in water. Removing bather waste is critical to chlorine efficiency, as it would otherwise need to be oxidized by chlorine or a secondary oxidation system. Phosphates cannot be oxidized or removed by chlorine, so you need a phosphate remover to get rid of them.
