Anytime you are in your hot tub water, it’s easy to bring contaminants in with you. Body oils, cosmetics, sun screen, detergents, perspiration, and more can come in on your skin and swim suit. Oxidizing, or shocking your water, helps to break down and remove contaminants, all while making your water clear and comfortable. Routine, weekly shocking helps to maintain balance in your spa.
