Where to put a powerhead

[Crimsontopper]

So I have an IM 10 and I got a koralia 240, but I'm not sure where to put it. I know I don't want it on the front glass, but other than that I'm open to suggestions. If I put it in either of the back two corners it prevent debris from getting to the overflow. Any ideas?

Like the back corner idea. Gets thing moving in the right direction
