The Intelligent Pool Suite for
Every Pool Owner.

For rectangular pools: length × width × average depth × 7.5 = gallons. For oval pools: length × width × average depth × 5.9. For circular pools: diameter × diameter × average depth × 5.9. If you're unsure, your pool builder or manual will have the volume.

Liquid test kits (like the Taylor K-2006) give more accurate readings than test strips, especially for chlorine and CYA. Test strips are faster and fine for quick checks. For salt levels, a digital salinity meter is more accurate than strips.

We use standard, industry-accepted pool chemistry formulas. Results are accurate for typical conditions. Real-world variables like water temperature, existing mineral content, and equipment can cause small variations — treat our results as a reliable starting point and verify after adding chemicals.

No — add one chemical at a time and run the pump for at least 15–30 minutes between additions. Never mix chemicals together before adding to the pool. Start with pH and alkalinity before adjusting chlorine or salt.

All current calculators are completely free to use with no account required. We may introduce optional features in the future, but the core calculators will remain accessible. We'll communicate any changes clearly before they happen.

No. All calculations run in your browser. Your pool volume, chemical readings, and results are never sent to or stored on our servers. Nothing you enter leaves your device.
