Pool Chem: Dosing Calculator

Snap a test strip, get the exact ounces of each chemical to add — in the right order. Clear water without paying a pool service.

Pool Chem ends the guesswork. Enter your pool or spa volume once, then log your water test — free chlorine, pH, total alkalinity, calcium hardness, cyanuric acid, and salt. In seconds, Pool Chem tells you the exact amount of each chemical to add and the order to add them safely.

No more chemistry. No more "add a little and hope." Just clear water.
