Item Details

Clear Spa Crystal Shock Oxidizer

Crystal Shock Oxidizer is a non-chlorine shock that keeps water crystal clear. It works by removing contaminants such as oils, organic waste, ammonia, sweat, urine and more to ensure your water remains crystal clear and odor free.

Non-chlorine oxidizers increase the effectiveness of bromine or chlorine in hot tub water by removing the contaminants that deplete your sanitizer levels. These contaminants are also the cause of odors and eye and skin irritation. By getting rid of these contaminants you improve the smell of the water and you can reduce or even eliminate skin and eye irritation.
