Pool Balance Alkalinity Up (5 lb) is a granular alkalinity increaser formulated to raise total alkalinity and help prevent pH drift. Proper alkalinity levels protect pool surfaces, reduce corrosion, and improve swimmer comfort by keeping pH stable.

This product dissolves quickly and distributes evenly throughout the water, making it ideal for routine maintenance or correcting low alkalinity caused by rain, heavy use, or chemical imbalance. Safe for all pool types, including plaster, vinyl, and fiberglass.
