A device, formula, or software designed to determine the volume of water circulating through a swimming pool’s filtration system within a specified period, typically expressed in gallons per minute (GPM) or gallons per hour (GPH). For example, if a pool’s volume is known, and the desired turnover rate (the time it takes to filter the entire pool volume) is set, this can compute the necessary circulation for optimal water quality.
Accurate assessment of a swimming pool’s circulation is crucial for maintaining water clarity and sanitation. Sufficient circulation facilitates the efficient distribution of sanitizers, prevents algae growth, and removes debris. Historically, calculations were performed manually, but contemporary tools offer ease of use and precision, leading to improved pool maintenance practices and reduced chemical consumption.
