CV-700 Catalytic Enzyme and Phosphate Remover Water Cleaner Concentrate is a unique, stabilized enzyme system with a phosphate remover. It effectively catalyzes the bio-oxidation of non-living organic contaminants and removes ortho-phosphates commonly found in pools, spas and other recreational water. Routine application of CV-700 will positively maintain water clarity, reduce both carbon-based and ortho-phosphate contamination of water, and boost chlorine efficiency.
