Pool Chemical Calculator App

This pool chemical calculator app runs in any mobile browser. No App Store download, no Play Store install, no account signup. Save this page to your phone's home screen and get a one-tap chemical dosing tool that handles chlorine, pH, alkalinity, and cyanuric acid for any pool volume from 500 gallons up to 200,000 gallons. Uses the same dosing formulas as the paid pool chemical calculator apps.

Pool Chemical Calculator App Target Ranges

  • Free Chlorine: 1-3 ppm (3 ppm when shocking)
  • pH: 7.4-7.6
  • Total Alkalinity: 80-120 ppm
  • Cyanuric Acid: 30-50 ppm outdoor, 0-20 ppm indoor
  • Calcium Hardness: 200-400 ppm

Dosing Formulas Used by This Pool Chemical Calculator App

  • Liquid chlorine (10%): 10.5 oz per 10,000 gal raises free chlorine by 1 ppm
  • Granular cal-hypo (65%): 1.55 oz per 10,000 gal per 1 ppm
  • pH Up (soda ash): 6 oz per 10,000 gal raises pH by 0.2
  • pH Down (dry acid): 12 oz per 10,000 gal lowers pH by 0.2
  • Muriatic acid (31.45%): 26 oz per 10,000 gal lowers pH by 0.2
  • Alkalinity increaser (baking soda): 1.5 lb per 10,000 gal raises TA by 10 ppm
  • Cyanuric acid: 13 oz per 10,000 gal raises CYA by 10 ppm

These are the same industry-standard formulas used by the Pool Math app, Pool Chemistry Monitor, and every other pool chemical calculator app on the stores.

Why Use a Pool Chemical Calculator App?

Guessing chlorine and pH doses is how pools turn cloudy, green, or dangerous. A pool chemical calculator app takes the math off the top of your head and gives you precise ounces and pounds for the volume and ppm difference you have right now. The two biggest wins:

  • No overdosing. Pool chemical overdoses cost money and can damage equipment (muriatic acid is especially unforgiving). A pool chemical calculator app prevents the "dump and hope" approach.
  • Correct dose sequence. The order matters: alkalinity first, pH next, CYA third, chlorine last. This pool chemical calculator app shows the sequence alongside each dose.

How to Use This Pool Chemical Calculator App From Your Phone

  1. Test your pool water with strips or a drop-based kit.
  2. Open this page in your phone browser (Chrome, Safari, Edge, Firefox).
  3. Enter pool volume and your test results for chlorine, pH, alkalinity, and CYA.
  4. The app returns exact ounces of liquid chlorine, pounds of cal-hypo, ounces of pH adjuster, pounds of baking soda, and ounces of CYA.
  5. Add chemicals in the order the app shows, waiting at least 4 hours between each.

To use it like a native app, tap the browser's "Add to Home Screen" option. Chrome on Android and Safari on iOS both create a one-tap icon that launches this page instantly.

Pool Chemical Calculator App vs Native Mobile Apps

Most native pool chemical calculator apps cost $2-10 or push ads. This web-based pool chemical calculator app is free, never needs updating, and works identically on iPhone, Android, iPad, and any laptop. The math is the same. The only thing native apps add is offline access, which matters only if you dose chemicals in a field with no cell signal. For a typical backyard pool, the web version is simpler and the total cost of ownership stays at zero.
