SeaKlear Phosphate Remover, 1 gal Bottle | 90336SKR

Some of the best pool-care ideas come straight from nature. SeaKlear built its name in the mid-1980s on chitosan — a natural clarifier derived from recycled crab shells — and its legendary Chitosan Clarifier has been polishing pool water for more than 30 years. Originally developed as a division of HaloSource Inc., SeaKlear joined the Natural Chemistry family in 2016 under parent company NC Brands, which today is part of the BioLab family of water-care brands. The lineup goes far beyond clarifiers: enzyme-based cleaners, phosphate removers, metal and stain control, and problem-solving formulas that tackle cloudy water at the source instead of masking it. For DIY pool owners who want clear, sparkling water without harsh extras, SeaKlear delivers science you can actually see.
