Readings before guests
Before opening, check the readings that matter most for the day and write them where you can find them later. Start with disinfectant and pH, then add the rest of your opening notes in Poolsheet or your own log. If you want a broader setup guide, see guides and the features page.
While the venue is open
During the day, repeat the readings your local code asks for and note anything that changes with traffic, weather, or bather load. Keep the log simple so staff can update it fast through the app waitlist or with a paper sheet at the deck. The point is to keep a clear record, not to guess at treatment.
The weekly and monthly notes
Some checks are not part of the daily routine. The model code note on this page names the weekly and monthly windows, so use that as your reminder for deeper inspection, cleaning, and record review. If you are building a longer routine, start from the home page and shape the checklist around the tasks your venue must keep on file.
What to leave off the list
A checklist should not promise a dose, a fix, or any result you cannot confirm with a reading. It should also not replace local rules, staff training, or a written response plan. Poolsheet helps you log what happened, not decide what a venue should claim.
Test rhythm in the model code
- Before opening each day, test free chlorine or combined chlorine or total bromine, and pH (section 5.7.5.1).
- Manual disinfectant feed with no automated controller: also test free chlorine or bromine and pH every 2 hours while the venue is open (section 5.7.5.2).
- Automated disinfectant feed: test free chlorine or total bromine and pH every 4 hours while the venue is open (section 5.7.5.3).
- Total alkalinity is tested weekly (section 5.7.5.5). A numeric alkalinity window is not printed here.
- Calcium hardness is tested monthly (section 5.7.5.6). A numeric hardness window is not printed here.
