Pool pH Calculator
Pool pH should sit between 7.2 and 7.8 for swimmer comfort and chlorine effectiveness. Enter your pool volume and current pH; the calculator will tell you the exact ounces of muriatic acid (31.45%) to lower it or pounds of soda ash to raise it. If you have a Taylor acid-demand reading (R-0015 drops), enter it for a more precise dose. Free, no signup.
Don’t know your pool’s gallons? Rectangle ≈ length × width × avg-depth × 7.5; round ≈ π × radius² × avg-depth × 7.5; freeform is roughly 0.45 × length × width × avg-depth × 7.5.
