Poolsheet is a chemical log for commercial pools and spas, built to help you record what you test without pretending to replace the label. If you want a place to start, visit the home page, browse the guides, or read about the features.
Why there is no dose button
You may be asking, how do I calculate pool chemicals? The short answer is that Poolsheet does not calculate a dose for you. A real addition depends on the product label, the water conditions, and the local code that applies to your site.
What you can record instead
You may be asking, what should I write down? Record the reading you tested, the chemical you considered, the time of the test, and any note that helps you compare the next check. If you want a simple place to start, see the pool log sheet or join the waitlist.
Label and local code
You may be asking, where does a real dose come from? It comes from the product label and the local health department code for your facility. If a model code note on this page gives a window or limit, use that note and verify it against the current label before you add anything.
The blank sheet
You may be asking, is there a log instead of a calculator? Yes. Poolsheet gives you a blank sheet for readings, notes, and follow up. It is built for teams that want a clear record without a guessed dose.
Chlorine and pH windows in the model code
This page does not calculate a chemical dose. Pounds, gallons, and acid amounts are not stated, because a dose depends on the product label and the local code.
- pH of the water: 7.0 to 7.8 (section 5.7.3.4.1).
- Minimum DPD free chlorine when the venue is not using cyanuric acid: 1.0 ppm (section 5.7.3.1.1.2.1).
- Minimum DPD free chlorine when the venue is using cyanuric acid: 2.0 ppm (section 5.7.3.1.1.2.2).
- Spas: minimum DPD free chlorine 3.0 ppm (section 5.7.3.1.1.2.3).
- Maximum free chlorine: do not exceed the product label (section 5.7.3.1.1.5). This page does not print a numeric chlorine ceiling.
- Cyanuric acid at aquatic venues stays at or below 90 ppm (section 5.7.3.1.3.2). If cyanuric acid is 300 ppm or higher, the venue stays closed until remediation (section 5.7.3.1.3.3).
