GLB Filter Rinse Cleaner Quart Bottle

Restores “Like New” efficiency to swimming pool sand filters. Filter Rinse is a unique, dual action product that removes both caked-on organics and inorganics from the sand particles. Regular use will renew the sand particles and keep the filter operating at maximum efficiency to yield crystal clear water with longer periods between backwashings.Dosage: Adding filter rinse to the skimmer during the backwash cycle removes this caked-on material, and permits free and even water flow through the sand. 8 oz. per backwash.
