Those people looking to get out of chemicals by purchasing a salt system for their pool must be aware they will still be using CYANIDE based cyanuric acid (stabilizer or conditioner), muriatic acid, algaecide and chlorine shock. The heated spa water will have a noxious odor and both the pool and spa will contain the salt, sodium and measurable chlorine residual. You will actually exaggerate your hardwater or scale issues on the pool and water features with a salt system. Most importantly, while a salt generator initially should cost $900 to $1,100, the replacement cell will cost $500 to $850 every third year, best case making the six year cost of a salt system (NOT including the chemicals) the most expensive option. ECOsmarte requires copper replacement only every 3 to 5 years for $175. If your objective is to get out of chemicals and lower your operating cost, ECOsmarte offers (a slightly more expensive system initially) the only method to sanitize your pool without chemicals and after more than 20 years remains the only creditable non chemical option with 6 day toll free support at 1-800-ION-SWIM.
