How this Pool Baking Soda Calculator works
The default planning factor assumes about 1.5 pounds per 10,000 gallons for each 10 ppm alkalinity increase. The estimate scales directly with pool volume and the requested ppm change.
Important: Test water accurately, follow the product label, add chemicals in stages and allow circulation before retesting. Do not use this estimate to correct pH without considering the full water balance.
What assumptions should I verify?
Verify every entered quantity, rate, unit, product specification and local requirement before relying on the estimate. U.S. conventions are primary where location matters.
Is information sent anywhere?
No. Calculations run locally in the browser and this calculator sends no entered information to a remote service.
