How does a Chlorinator work?
As pool water passes through the chlorine generator cell, pumped through by your filter pump, the salt in the water is turned into Hypochlorous acid. Hypochlorous acid is the exact same chemical that is produced when any chlorine is added to pool water, whether you use sticks, tablets, granular or liquid. As the water returns to the pool, it will introduce the newly produced chlorine, preventing algae, bacteria and killing micro-organisms, creating a safe and sanitary swimming environment.
The salt level required to maintain a safe, chlorinated pool is about 2500 to 3500 PPM (parts per million). The human tongue cannot taste salt until the PPM is around 5000. As a reference point, the ocean is around 40000 ppm. The amount of salt in the pool is usually not noticeable. Once the salt is added to the pool, only small additional amounts are needed, usually annually, unless the pool is drained or a significant amount of water is removed. Also, the salt level is low enough so there is no danger of equipment corrosion. Saltwater pool systems also make the water softer, leaving a more refreshed feeling after swimming, with less chlorine smell.
