Keep your above-ground pool water clean, fresh, and sparkling with the Intex Krystal Clear Saltwater System and Sand Filter Pump. The all-natural sand provides excellent water filtration as the 6-function control valve allows the pool owner to filter, backwash rinse, recirculate, drain, and close the system. The built-in 24-hour timer adds to the hassle-free experience of maintaining a cleaner pool. Equipped with the Ground Fault Circuit Interrupter, which is an added safety feature that shuts off the pump if electrical current is exposed to water. This effective pump requires virtually no maintenance except the replacement of sand. With the Saltwater System’s electrocatalytic oxidation process, water molecules are split into oxidants that help keep the water clean. The amount of Sodium Hypochlorite generated by the saltwater system is reduced by approximately 60%, much less than other saltwater systems generate. Enjoy the same process used at many resorts in your pool with the 16-inch Intex Krystal Clear Sand Filter Pump and Saltwater System.
