This powerful 1 lb bag utilizes oxygen-based technology to break down oils, sweat, and environmental debris without affecting your pool’s chlorine levels. Because it is non-chlorine, it will not bleach liners or swimsuits, making it the ideal choice for routine maintenance and crystal-clear “sparkle” in all pool types
