Power Powder Plus 73 dissolves quickly and leaves minimal residue, ensuring thorough sanitization without significantly increasing calcium hardness levels in your pool water. As a non-stabilized chlorine shock, it contains no cyanuric acid, meaning it won’t raise stabilizer levels, making it perfect for evening use to reduce UV degradation.

Add 9-18 oz. per 10,000 gallons for super chlorination or 3 oz. per 10,000 gallons for routine maintenance to achieve 5-10 ppm available chlorine. Safe for use in all pool types, this powerful pool shock is an essential tool in your pool care arsenal.
