I'd put it on the tank as is, and see how you like it. You might like a high flow rate in the tank.
You could put a valve on the output side of the filter, and use that to cut the flow back, but don't cut the flow more than 20% or so.
I wouldn't think of it as a sump, by the time you put media in it, it's going to hold a lot less water than you though.
