Probably not a big deal but does anyone have any opinions about overflow position in the tank. I have a 75E that I am setting up as a reef tank. I need to mount a hang on overflow. I would like to hang it on the left side of the tank because it's easier to plumb everything and hide it at that end. Any issues in terms of flow from the other end of the tank? It seems like it should be centered so that it draws from both ends. Any opinions?
