Chemical Dosage Calculator
Stop guessing. Calculate exactly how much chemical you need to add to balance your pool or hot tub water.
Why is precise chemical dosing important?
Guessing how much chlorine or acid to add can lead to dangerous water chemistry. Over-dosing can bleach your liner, corrode your expensive equipment, and irritate swimmers' skin and eyes. Under-dosing leaves your water unprotected against algae and harmful bacteria.
This calculator takes the guesswork out of pool and spa maintenance. Simply enter your water volume and current test results, and we'll tell you the exact amount of chemical needed to reach perfect balance.
