Keep your above ground pool water clean, fresh, and sparkling with the 14-inch Intex Krystal Clear Sand Filter Pump and Saltwater System. The all-natural sand provides excellent water filtration as the 6 function control valve allows the pool owner to filter, backwash and rinse, recirculate, drain, and close the system. The built-in 24-hour timer adds to the hassle-free experience with maintaining a cleaner pool. The system generates a pump flow rate of 1,500 gallons per hour and can be used for a maximum pool size of 8,500 gallons. 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 besides the replacement of sand every 5 years. With the Saltwater System s electrocatalytic oxidation process, water molecules are split into oxidants that help clean the water. 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 own pool with the 14-inch Intex Krystal Clear Sand Filter Pump and Saltwater System.
