For 27 years I treated a 28,000 gallon pool with chlorine dispered from a floating device. 27 years of rubber gloves, chlorine fumes, fluctuations in PH due to acid rain, alaecides and shcok treatments. NO MORE! Mid-summer of 2005 I began using the Ecomatic Chlorine Generator, putting an end to chlorine fumes, stained blue jeans, and PH UP. Yea!! $20 of salt versus $250 for chlorine and $75 for PH UP, Shock, and Algacide. Set a dial and relax!!!! John, Professor Emeritus: Eau Claire, WI While we were working with you this past spring my wife was interested in the Eco-Matic System. You explained it to us, we bought it, but I was still skeptical. At times during the work week our pool gets neglected and in the past we have had problems with algae growth. This summer we have had no algae in our pool, and the water is as clear as it can be. Fill pool, add salt, no chemicals, no chlorine smell, and easy maintenance. We love it!!!
