When you get bored......

If you want to put outlets low in the back, they need to be on a closed loop system. I did my tank the way Mr Om is suggesting, with 2 separate pumps. The closed loop is on the OM, with outlets near bottom of tank. Then, the sump return goes over the top of tank, and points straight down the back wall of tank. This makes a nice rolling of the water. If you were to stand on the right side of tank, and look into end of tank, water will be making a clockwise rotation in the tank. I don;t have any debris settling anywhere. 3500GPH combined flow on a 130g tank
