Pool Flow Rate Calculator
The pool turnover rate is important for proper filtration. Not cycling enough water through the filter can result in swimming pool algae blooms, cloudy pool water, and water balance issues.
Calculate the flow rate needed to achieve proper filtration.
One turnover only filters 37% of the water. After a second turnover, 86% of the water has been filtered. It takes four turnovers to filter 98% of the pool water. Many commercial codes require a minimum of 4 turnovers per 24 hours.
Different water use has different filtration needs; therefore, they have different recommended target turnover times. The volume of water, activity, and contamination load must be considered when factoring in the optimal turnover rate.
