How often must pool chemistry be recorded after the initial check?

Pool chemistry must be recorded at intervals not exceeding two hours to ensure that the water quality remains safe for swimmers and meets health regulations. Monitoring at this frequency allows staff to promptly identify any fluctuations in chemical levels that could pose risks, such as improper pH levels or sanitizer concentrations, and to take corrective actions if necessary.

Timely checks are crucial, especially in heavily used pools where bather load can significantly affect water chemistry. Recording the readings within this two-hour window ensures that critical adjustments can be made to prevent potential health hazards or compliance issues. While other options suggest shorter intervals or less frequent checks, they might not provide the same level of vigilance needed to maintain safe pool conditions.
