I'm just curious how long everyone runs their sand pump?? Do you run it 24/7, 8 hours, 10 hours, or 12 hours?? Do you run it overnight or during the day? I'm currently running mine 12 hours (10am-10pm) and the swp for 9 hours. Of course, summer is almost over and we will be closing it next month, so really just info for next season.
