GLB Filter Rinse is a one step formula that cleans sand filters fast. Backwashing with plain pool water alone cannot fully remove the caked-on oils and minerals deposits from the sand particles. This product renews the sand particles and keeps the filter operating at maximum efficiency to yield crystal clear pool water with longer periods between each backwash. Filter Rinse is compatible with chlorine, bromine, ozone, and biguanide sanitizers.
