Fast acting bacterial pond clarifier. Specially selected and unique strains of bacteria that grow faster than conventional enzyme-producing bacteria - and release a natural polymeric coating into the water that will flocculate small particles. The natural flocculation process will clear water of all materials - including clay, silt, and debris. At the same time, the bacteria will consume high volumes of phosphates and nitrates. Treats up to 4000 gallons per 16 oz.
