Hayward AquaTrol Above Ground Salt Chlorine Generator 18K gal | W3AQ-TROL-HP Challenger High Flow Pumps Parts and Accessories is a replacement part thatThe AquaTrol is an automatic chlorine generation system with a built in filter pump timer designed specifically for above ground pools. The operation requires a low concentration of salt (sodium chloride) in the pool water at levels low enough that it normally will not be tasted. The AquaTrol automatically sanitizes your pool by converting the salt into free chlorine which kills bacteria and algae in the pool through a process called electrolysis.
