Salt Chlorinators (Chlorine Generators)

There are several brands of generators that use salt to make chlorine. 
Salt generators existed fifteen  years ago but they were not reliable. 
Within the last five years the technology has finally arrived.
Each of the following products are excellent and will make your swimming pool more enjoyable.
These are the only three I will install:

Aqua Rite by Hayward

AquaPure by Jandy

IntelliChlor by Pentair
