In The Swim Alkalinity Increaser

Maintain optimal water balance in your pool, spa, or hot tub with In The Swim Alkalinity Increaser. This essential granular treatment, formulated with 100% Sodium Bicarbonate, effectively raises low Total Alkalinity (TA) levels, which helps stabilize pH and chlorine. When TA drops below 80 ppm, water can become acidic and corrosive, potentially causing scale formation. By restoring balance, this product ensures your water remains safe, refreshing, and enjoyable. It is easy to apply and designed for consistent quality, making water maintenance straightforward for any pool owner.
