The SaltWater Magic Monthly Kit™ contains a combination of unique technologies that have been specifically formulated for chlorine generators. Phosphate remover reduces phosphate levels. Low phosphate levels help prevent calcium phosphate buildup on the cell and pool equipment. Naturally based enzymes: reduce non-living organic buildup in water, on pool surfaces, and in filter media. This minimizes maintenance and scrubbing - resulting in crystal clear water and a reduction in scum lines.
