What is / are the best times to run the pump? I've generally been running mine from 8 a.m. to 10 p.m. However, I'm considering a switch to 10 p.m. to 10 a.m.

Is it better to run it at night, daytime, etc? My heaviest use times are afternoons. My kids, even though they and their mother are home all day in the summer, don't swim much until after 4 p.m.

Thanks for the help.
