The Aqua Rite Electronic Chlorine Generator (also known as a salt chlorinator) is the largest selling system in the world. It automatically produces pure chlorine every day while the pool is being filtered and distributes it evenly throughout the pool via the return jets. The Aqua Rite uses a low concentration of salt dissolved in the pool water (below the level of taste) to produce up to 1.45 lbs of chlorine daily, enough for all residential pools up to 40,000 gallons. It is also NSF certified and approved for use on commercial and public pools. The Aqua Rite easily installs on the standard filtration systems, both for new construction and on existing pools.
