Who makes the best salt water system for home pools?
Don't trust anyone who tells you a certain brand is best, or gives you best water clarity, etc... All saltwater systems do the same thing, produce pure chlorine sanitzer (Hypochlorus acid) from the small amount of salt in the water.
The difference between brands is primarily how much chlorine it is able to produce in a day: its output. Don't buy a system unluss you know how many lbs/day of chlorine it makes. Most municipalites look for at least 0.04 lbs/day PER THOUSAND GALLONS. Don't buy a system unless you know how many lbs/day of chlorine it is capable of producing, or you may find yourself lacking sanitation capabilies.
The next biggest difference is a salt system's longevity and warranty. The electrolytic cell will wear out. If you have to replace a cell every three years, like some brands, you won't save very much money. There are brands that last 5, 6, 7 years or more.
There aren't many sites out there that do product reviews or comparisons for saltwater pool systems (or salt water chlorine generators, saltwater chlorinators, electronic chlorine generators, whatever you want to call them). I have only seen two sites that have information on ALL brands, and one with product comparisons, they are:
this question is the same as which saltwater pool system is the best?
Magnablu. this is a new system that uses magnesium chloride and potassium chloride rather then the sodium chloride that is presently being used. These salts are good for you and your garden as opposed to the old system. see link below
