So from what research I have done your flow should be slow through your sump or less than 5x. With only a 30 gallon tank that would be hard to do, using the head loss calculator there isn't really a pump out there that would hit the 150 or so that would be needed. I am thinking about going with a Mag 3 or a Rio 6 HF (350 gph). Either way it would come out to around 230 GPH.
My question is does everyone go by that? I see anything over a Mag 5 would be overkill is this pretty much the standard now or would it be better to go with a high flow sump to use the return as flow for the tank?
