The Bestway Hydrogenic Saltwater Chlorinator uses salt to produce chlorine to keep your pool clean whilst being more gentle on eyes, hair and skin than traditional chlorine. The Chlorinator separates the salt into the two basic elements of sodium and chloride, when the water passes through the electrolytic cell chlorine is produced which dissolves instantly into the pool water destroying bacteria and algae. This Chlorinator is compatible with cartridge and sand filter pumps of at least 330 gallons (1,249 litres) and with pools up to 7,000 gallons (26,498 litres) in capacity. Features an easy to use control panel and self locking function plus an automatic cleaning mode and adaptors to fit most above ground pools.
