Natural mineral purifiers greatly reduce the amount of chlorine that is needed in order to kill bacteria and sanitize your pool and spa. These purifiers use minerals such as silver and copper to naturally destroy contaminants that create cloudy and unhealthy spa and hot tub water. Mineral sanitizing systems allow you to use less chlorine, saving you money and giving you spa water that is noticeably cleaner and softer.
Nature2 by Zodiac has a full line of mineral purifiers from which to choose. Frog products by King Technology offer many choices of mineral purifiers as well. Both of these companies offer mineral spa sticks as well as products to use in your swimming pool.
