This One-step formula cleans sand filters fast. Backwashing with plain pool water alone cannot fully remove the caked-on oils and minerals deposits from the sand particles. Filter Rinse® renews the sand particles and keeps the filter operating at maximum efficienty to yield crystal clear pool water with longer periods between backwashings.

2. Start filter backwash as recommended by manufacturer.
3. While filter is backwashing, slowly pour 8 oz. into skimmer so that it goes directly through filter.
4. Continue backwash procedure according to manufacturer's instructions.
Use every time filter is backwashed to maintain crystal clear water clarity and maximum efficiency of sand filter.
