My sump isn't pretty, but it works for me :). The returns come in the left, where my skimmer sits, and spills over an 8 ich high weir. My skimmer always stays in the same depth water all the time. The middle has a dividing wall parallel to flow. You can see one powerheads in the first shot, pumping water along the bottom in the opposite direction of sump flow. The 2nd shot shows the other half of the middle section, where there is a power head below the little ball of Chaeto. From the middle section it just goes over a little wier to the return pump. Very simple set up.
The third shot just sorta shows the setup overall for orientation.
