There are many ways to sanitize a pool. Chlorine, Bromine, Peroxide, Lithium, Copper/Silver Ionisers to name a few. For most backyard pools, the most popular method by far is the Salt Water Chlorinator.
Salt water chlorinators are cost effective, convenient and hassle free. The majority of salt water chlorinators we sell these days are self-cleaning, and some models also have the ability to automatically control the pH in your pool by measuring the level and dosing acid as required. This level of automation makes life easy for the consumer, leads to a healthier and more comfortable pool to swim in, and is much better for the surface of the pool and filtration equipment.
