Hey how about those balls? lol
If you are running more then 2 to 3 times turnover of the rating of your skimmer through your sump without recirculating it you are wasting energy and your skimmer is almost worthless.
Oh yeah Michael Jackson is not dead, he was spotted at a Buick dealership with Elvis yesterday
so if my skimmer is ratted 350G (SWC 250) heavy bio load
and I have 160 gallons with a heavy bio load?
What should the turnover be in the sump.?!?
