I have a question, I have never done a sump filtration, thus I have questions since I am venturing this route. I read that the bigger the better, well regarless of what size sump, is there a way to figure what flowrate you should have in the sump? I am trying to use my sump as a mechanichal filter and bio filter (no skimmer, or refugeum at the moment maybe later for the ref.). The reason that I ask is because every type of filter pad I place in the sump restricts my flowrate quite a bit and that leads to a low level of water in the return pump chamber. Any help or ideas would be greatly appreciated thanks.
I would personally look at dual drains so around 1000-1200gph running through the sump. If you already have the tank you can either drill the tank and get a kit overflow box or you can buy a HOB overflow like a CPR box. Personally i would stay away from U tube boxes at all possible
Ok lets say I go with the 1200 gph flowrate in the sump (only in the sump). Is there a way to figure out the sump size based on this flowrate? You would not run 1200 gph flowrate in a 10 gallon sump, right?

Well you could....but it would be a little ridiculous. Along with flow you have to consider the tank it is suppose to be filtering. I would say roughly a 30-40 gallon sump. If you could fit bigger personally I would go bigger. On a 120 a 50 Gallon breeder sump would look great
