Have you considered a closed loop? I have a closed loop with a vortech MP20 at the end of my 60 X 24 peninsula and the flow is fantastic. You would probably need to plan it differently for a tank that is against the wall, but I find all my corals are happy.
My build is here to see what I did.:

Good luck!
