Use 28669EG Intex Krystal Clear Saltwater System with maximum pool size of 15,000 gallons, and enjoy the same all natural process used in many resorts and in-ground swimming pools to keep your pool sparkling clear with less maintenance! A filter pump flow rate of 700 - 3,000 gallons per hour is required. When the saltwater system is installed, a measured quantity of pure, natural salt is added to the pool water. The amount of salt that is added to the pool water is only one-tenth as much as ocean saltwater, so swimmers won't see, feel, or smell any salt. All you will feel is incredibly clean, fresh, sparkling water!
