Keep your above-ground pool water clean, fresh, and sparkling with the Intex Krystal Clear Saltwater System. Featuring an easy-to-read control panel with easy-access buttons, this saltwater system is easy to use and suitable for rectangular or round pools of up to 4,500 gallons. The built-in 24-hour timer adds to the hassle-free experience of maintaining a cleaner pool. The system is compatible with filtration pumps with a flow rate of 300 to 1000 gallons per hour. Equipped with the Ground Fault Circuit Interrupter, this added safety feature shuts off the pump if the electrical current is exposed to water. 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.
