The picture is perfect but this should be for a closed loop, not for a return, this will drain the tank if the power goes off.

Keep the sump/water treatment plant and return pump completely separate from your closed loop/tank flow system.

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

This will be an amazing set up

So where do you recommend i put the intake for the closed loop? And what size pump would you recommend for a 2' cube???

Mine is on the tank bottom, I used a 3 T fitting arangement and screens on the sides of the T's Your tank may just need one T. Hidden easily behind rockwork so you cant see it which I like

I agree, you can drill through the back and install a tee long leg going horizontal, install elbows on the ends of the tee pointing up to encourage the water to move in the same pattern.

OK here we go.

The returns will be constant flow from the sump, The closed loop will alternate from left to right, across the bottom of the tank. The drain for the closed loop will be just under the overflow. I dont want to place and tee in the tank as i dont want to see it. The aquascape im looking for will allow a Tee to be seen!:
