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, such as bacteria and algae. Next, the amount of natural chlorine generated by this saltwater system is greatly reduced, which results in clean water without the potential harsh side effects of packaged pool chemicals. It requires a filter pump with a flow rate between 2649L -11,356L per hour and is for use with a maximum pool size of 26,497 litres.
