This package includes a saltwater chlorinator and a wall-mounted surface skimmer. Keep your above ground pool water clean, soft, and refreshing with the Intex Krystal Clear Saltwater System. Its unique 2 stage technology uses an E.C.O. (electrocatalytic oxidation) process in which water molecules are split into highly powerful oxidants to destroy organic contaminants.Next, the amount of natural chlorine generated by this saltwater system is greatly reduced, which results is clean water without the potential harsh side effects of packaged pool chemicals. The Intex Krystal Clear Saltwater System requires a filter pump with a flow rate between 700-3,000 GPH and is for use with a maximum pool size of 15,000 gallons.
