PacifiClear F075001012PC Filter Cleaner and Degreaser, 1 qt Bottle, Liquid

Proper filtration and chemical treatment are equally important in maintaining good pool water quality. Filter cleaner is a unique proprietary blend of alkaline salts, solvents, surfactants, sequestering and chelating agents formulated to remove oils, grease and filter clogging debris from DE, cartridge and sand filters in pools. While the alkaline compounds, solvents and surfactants act as cleaning agents, the sequestering and chelating agents act as metal/mineral suspenders and removers by keeping the ions dissolved in water, until they are removed with the debris laden wastewater from the cleaning process.
