I struck up a conversation with a guy somehow about pools and whatnot. It ended up with us on the subject of when the best time to run your filter/pumps. He swore (and very adamantly) that you're a fool if you run your filter/pumps in the day. He said the best time to do it was overnight. He said you will mess up your balance etc. if you did it during the day.
Is there any truth to this? If so, I'm the biggest idiot on the planet because I run mine from 10am-6pm. Should I adjust my timers for a different time/part of the day?
