Water that looks attractive can still be out of balance. Testing should occur before use and more often during heavy use, heat or rain.
Choose a reliable method
Compare drop kits, strips and digital tools by range, precision, storage and calibration needs.
- Check expiry
- Use clean samples
- Follow timing precisely
Track core readings
Disinfectant and pH are basic controls; other values affect stability, comfort and surfaces.
- Use the pool manual
- Keep a log
- Retest after adjustment
Respond to unusual conditions
Heavy rain, high bather load, equipment failure and contamination can require closure and additional testing.
- Do not guess doses
- Follow official guidance
- Reopen only when clear and in range
Know when to call for help
Persistent cloudy water, recurring algae, staining or unexplained demand may need professional diagnosis.
- Bring water logs
- Check circulation
- Avoid repeated blind additions
