MP 10 placement

[pstank1]

I've got a 30l x 20h x 18d tank with two separate rock formations and a calfo overflow along the back. I picked up an mp 10 and was trying to figure out the best location for it. I was thinking about placing it in the center of the back, just underneath the overflow and between the two rock formations. Would that be a good location for it?

I've got some extra pumps that i can suplement the flow with and my return is around 350 gph with head loss.
