The XtremepowerUS Salt Water Chlorine Generator is the most advanced saltwater chlorinator on the market that is designed specially for any hot tubs or SPAs up to 3,000 Gal. Keep your pool crystal clear and sparkling clean with an automatic chlorine generation system for pool sanitization. This chlorine generator virtually eliminates the need for additional sanitizing chemicals such as chlorine, shock, algaecide and other chemicals. This purification process functions by converting the salt used in the pool into free chlorine which kills bacteria and algae in the water. These reactions will continuously recycle the pool water in connection with your pool pump everyday to maintain crystal-clear pool water and produce luxuriously soft and natural-feeling water for your residential swimming pool.
