Clorox Pool & Spa Alkalinity Increaser 16 lb — Keeps pH Balanced

Achieve stable pool chemistry with ease

Maintaining proper total alkalinity helps keep your pool’s pH more steady, reducing the need for frequent adjustments. The Clorox Pool & Spa Alkalinity Increaser is a granulated formula designed to be easy to apply and to dissolve quickly, so you can spend more time enjoying the water and less time measuring and re-testing.

By supporting balanced alkalinity, this product contributes to a more comfortable swimming experience. When pH stays within a predictable range, swimmer experiences can feel calmer, and the water may feel gentler on eyes and skin. It also helps protect metal and surface components from corrosive shifts in chemistry, which can matter for pool equipment and finishes over time.
