How to Use This Calculator
- Enter your pool's water volume in gallons — use the Pool Volume Calculator if you don't know it.
- Input your current pH and target pH (ideal range is 7.2–7.6); the calculator will compute muriatic acid or soda ash needed.
- Enter current and target free chlorine levels in PPM (target 2–4 PPM) to calculate chlorine addition.
- Set current and target total alkalinity (ideal 80–120 PPM) to find the baking soda dose required.
- Review Acid Ounces, Chlorine Pounds, and Baking Soda Lbs outputs for each chemical to add.
- Add chemicals separately with the pump running and retest after 4–6 hours before adding the next chemical.
