What Is A Salt Water Chlorinator?

Everyone within the in ground pool industry is raving about salt water chlorinators! However, you may be wondering what exactly salt water chlorinators are. Salt chlorinators use salt to create chlorine for your swimming pool sanitization. Salt chlorinators do this by using a process of electrolysis. This process creates  a pure form of chlorine from a small amount of ordinary salt that can be used in your salt water pools over and over again.

To clarify, chlorine is still the sanitizing agent in salt water pools. Salt itself is not doing the sanitization. Salt in the form of magnesium chloride, potassium chloride or sodium chloride is dissolved into the pool water.Then it is converted by the salt chlorinator into chlorine which sanitizes the pool.  The salts or minerals pass through the electrolytic plates in the chlorinator cell to form chlorine. Chlorine in turn, kills all the contaminants in the pool and prevents harmful bacteria and algae from forming.

The ocean is about 35,000 parts per million in salt content, where a salt water chlorinated pool is only about 3,000 parts per million. The upside? The pool will not feel or taste salty, just soft.
