I have a 9200 gal / 35000L pool and a 24" Hayward sand filter. It's flow rate is 235LPM, ie every 2.5 hours the whole body of water is filtered once.
How many hours should I run it in summer at a minimum? I do remember reading somewhere the water should be filtered twice daily at least, ie 5 hours run time, would this be correct?
Also a Pool School article mentioned running the pump during the hottest part of the day. Currently I run it 3 hours from 9-12am and then 3 hours from 9.30pm-12.30am. Would it be more efficient to run it continuously from 9am for the required hours?
