Hayward Goldline Aqua Rite Salt Water Chlorine Generators 40.000 Gallons With T-Cell-15 P/N: AQR15 The Aqua Rite is the easiest way for you to sanitize your pool, and keep your crystal clear and silky smooth! The Aqua Rite uses common salt (the same salt used in water conditioners) and converts it into "free" chlorine. The chlorine sanitizes your pool and then reverts back into salt. That's right, the salt is recycled and never wears out. With only a teaspoon of salt per gallon, the Aqua Rite produces enough fresh chlorine (up to 1.45 lb per day) to keep a 40,000-gallon pool sparkling clean without the chlorine smell. You'll never again have to worry about red irritated eyes, dry itchy skin, bleached bathing suits or green hair! Soft, Crystal Clear, Luxurious Water No more hassles buying, storing, measuring chlorine. For any pool up to 40,000 gallons Digital display of salt level and diagnostic info plus 8 LED status indicators. Easy to use dial adjustment to generate more or less chlorine.
