Borax Pool pH Calculator - Raise pH Safely
Calculate how much 20 Mule Team Borax you need to raise your pool's pH. Safe, effective, and cheaper than pH Up chemicals.
Why Use Borax to Raise pH?
Standard "pH Up" chemicals are usually Soda Ash (Sodium Carbonate). While effective at raising pH, Soda Ash also significantly raises Total Alkalinity. Borax (Sodium Tetraborate) raises pH with less than half the alkalinity impact of Soda Ash.
Is Grocery Store Borax Safe for Pools?
Yes. 20 Mule Team Borax is a common household laundry booster that is 100% Sodium Tetraborate. It is safe for all pool finishes (plaster, liner, fiberglass).
Pro Tip: If your alkalinity is also low, use baking soda instead of Borax. Check the exact dose with our Baking Soda Alkalinity Tool.
