Questions
How often do I have to test a commercial pool?
It depends on the state. New Jersey asks for free chlorine and pH every 2 hours while open, Ohio before opening then every 4 hours, Georgia and Illinois twice a day, Texas, Arizona and North Carolina once a day, California daily (twice a week for small HOAs). Pick your state above: the tool shows the rule and the section of the code it comes from.
How long must I keep the pool log?
From 6 months (North Carolina) to 3 years (Texas, Illinois, New Jersey, Washington); California and Ohio say 2 years. Where the state rule sets no period, the CDC model code asks for 3 years. PoolChemLog Pro keeps the log for at least 3 years, even after you cancel.
What if my state has no statewide pool code?
Then the county or city health department sets the rules, and most of them follow the CDC Model Aquatic Health Code. The tool says so plainly and shows the model code's numbers rather than inventing state ones.
Will the inspector accept a digital log?
Most state codes ask for records that are kept and available on request, not paper specifically. PoolChemLog exports your state's sheet filled in, a full inspection report and a read-only link. Entries are never edited: a correction is a new, visible entry with its reason. Where a rule demands a bound book (some counties), print the export monthly.
Is the log sheet really free?
Yes, with no email asked: pick the state and pool, download the PDF, print it. The calculators are free too.
