Maintain a refreshing above-ground pool experience and keep your above-ground pool water clean, soft, and refreshing with the Iintex Saltwater System and Sand Filter Pump Set for Above Ground Swimming Pools. Say farewell to red eyes, adversely affected hair, faded swimsuits, and damaged pool liners.The Salt Chlorine Generator's 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 in clean water without the potential harsh side effects of packaged pool chemicals.
