Broadcast baking soda directly over the deep end of the pool with pump circulating. Allow 6 hours of turnover before retesting.
Baking Soda Dosing Formula
To raise Total Alkalinity by 10 PPM in a 10,000-gallon pool, add 1.5 lbs (3 cups) of baking soda.
Baking Soda (lbs) = (Pool Gallons ÷ 10,000) × (Target TA − Current TA) × 0.15Related Water Balance Tools
Frequently Asked Questions About Baking Soda in Pools
Clear answers on using household sodium bicarbonate for swimming pool maintenance.
1.5 pounds (approx. 3 cups) of pure baking soda per 10,000 gallons of pool water will raise Total Alkalinity (TA) by 10 PPM.
Baking soda (sodium bicarbonate) significantly raises Total Alkalinity and has only a very mild effect on pH. It acts as a pH buffer, preventing rapid pH swings.
Yes! Pure grocery store sodium bicarbonate (baking soda) is chemically identical to commercial pool alkalinity increaser products, usually at a fraction of the price.
You can swim 15 to 30 minutes after broadcasting baking soda into the pool, provided the circulation pump is running.
