Florida health code requires commercial pool operators to maintain a written record of water chemistry testing for every day the pool is in operation. This isn't a best practice recommendation — it's a legal requirement under Chapter 64E-9 of the Florida Administrative Code, and it's one of the first things a health department inspector will ask to see.
Many operators treat record keeping as a formality. Inspectors — and plaintiff's attorneys in liability cases — treat it as evidence. Here's what you're required to keep, how to keep it correctly, and what gaps in your records signal to an inspector.
What must be logged
For every operational day, your chemical log must record:
- Date and time of each test
- Free chlorine reading (in ppm)
- pH reading
- Total alkalinity (tested less frequently — at minimum weekly, but should be logged whenever tested)
- Cyanuric acid (monthly minimum for outdoor pools, logged when tested)
- Name or initials of the person who performed the test
- Corrective action taken if any reading was outside the required range — what chemical was added, in what quantity
Tests must be performed at minimum twice per operational day — before opening and once during operating hours. Many health department inspectors expect to see a mid-morning and afternoon entry for facilities with long operating hours.
Format requirements
Florida health code does not mandate a specific log book format, but the log must be a written record maintained on-site and available for inspector review on demand. Pre-printed log books with columns for each required parameter are the most common and most defensible format — they make it obvious when an entry is missing and demonstrate a systematic approach to record keeping.
Digital logs (tablet apps, service management software) are increasingly common and are generally acceptable as long as the record can be produced on-site during an inspection. A cloud-based system that requires internet access to retrieve during an inspection is a practical risk — ensure you can produce the current and recent logs without connectivity.
How long records must be kept
Florida health code requires chemical logs to be retained for a minimum of two years. Keep them on-site or immediately accessible — not in off-site storage that can't be retrieved during an inspection. For liability purposes, retaining records for five or more years is advisable; a pool-related illness or injury claim can arise well after the incident.
What inspectors look for in your log
Inspectors are experienced at reading chemical logs and will notice:
- Missing entries — days with no log entries suggest the testing didn't happen. Even one missed day raises questions.
- Identical readings across multiple test times — the same chlorine and pH reading at 9am and 2pm on an active pool day suggests the second test wasn't actually performed, just copied.
- Readings consistently at the edge of the required range — a log that shows pH of 7.2 or 7.8 every single day suggests the log may not reflect actual conditions.
- No corrective action logged when readings are out of range — a log showing a chlorine reading of 0.5 ppm with no corrective action noted is a significant finding.
- Log not current — an inspector who arrives at 2pm and finds no afternoon entry yet is looking for an explanation. Have your morning test completed and logged before opening.
Contractor service reports vs. the chemical log
Your service contractor's visit reports are not a substitute for the facility's required chemical log. The contractor's report documents what they did during their visit. The chemical log documents every test performed every day the pool is operational — including on days when the contractor doesn't visit and tests are performed by facility staff.
Clarify with your contractor exactly who is responsible for maintaining the chemical log, who is performing mid-day tests on non-service days, and how both sets of records are stored and accessible. This should be explicitly addressed in your service agreement.
Building a compliant record-keeping system
- Use a pre-printed log book with columns for all required parameters — keep it at the pool, not in the office
- Assign specific staff responsibility for mid-day testing on non-service days
- Train all staff who perform testing on correct test kit procedure — inaccurate test results logged as accurate are worse than no log at all
- Review the log weekly as a management check — look for gaps or patterns that suggest testing isn't happening
- Store completed log books for a minimum of five years in an accessible location
- Keep contractor service reports filed separately but cross-referenced with the chemical log
