The Association of Pool & Spa Professionals (APSP) sets guidelines for pump and filter sizing that allow circulation flow to achieve at least two water turnovers per day. Operating your pump for 12 hours per day will ensure one turnover. Good circulation is necessary for filtration and dispersing the sanitizing chemicals throughout the pool water.
Note: Set the return jets to optimize the circulation pattern and to minimize dead spots where algae can bloom. The recommended angle for jets is 45° downward.
