pH Down | GLB | SKU 71253A | 10 Lb Bag | Fast Acting DIY Pool Owners

GLB pH Down balances your pool’s pH and alkalinity, creating water that’s comfortable to swim in and protecting equipment from damage. This 10 lb bag, part of a 4-bag case (SKU 71253A), offers reliable, long-term pH management for your pool.

Why it matters: when pH runs high, skin and eye irritation increases, chlorine efficiency drops, and metal or plaster surfaces face wear. GLB pH Down delivers a steady adjustment to reach ideal pool chemistry and alkalinity balance, reducing maintenance time and helping your water stay clearer.

How to use: test water, then add gradually according to pool volume and current pH. Re-test and repeat if needed. Keep a stock of the 10 lb bags to simplify routine maintenance and maintain consistent water chemistry across the season.
