Salt & Swim 3C is an automatic chlorine generation system for pool sanitization. It is designed for inground swimming pools up to 30,000 gallons that have a water proof 120V GFCI outlet within 3 feet of installation. Salt & Swim 3C requires a low concentration of salt (sodium chloride) in the pool water. It automatically sanitizes your pool by converting the salt into free chlorine which kills bacteria and algae in the water. Chlorine will revert back to sodium chloride after killing bacteria. These reactions will continuously recycle virtually eliminating the need to add sanitizing chemicals to your pool. This unique low cost chlorine generator uses a replaceable electrolytic Cell (SAS-CELL) that is designed to produce 200lbs of 100% available chlorine over its lifetime.
