Here's mine. I've been slowly "tuning" it over the last 6 months. In summary, it is in the basement below my DT. 150g sump/refugium split long ways down the middle. On the other side of the wall, I've got two 30g cubes plumbed into the DT sump and my clown grow-out system (two 40G, 20G & two 10G larvae tanks all plumbed into a 45g sump. The 30 cubes are fairly new - just finished cycling some dry rock (nice and white).
You can't see all the plumbing behind the cubes and the grow-out, but they're all connected to the same return (1' down from the ceiling running the length) and drain line (just below the GO platform and behind the chemical bottles running the length). A series of ball valves on each line dictates the seperation of systems. I can flip a ball valve on the return (Barracuda DT side - Iwaki40 GO side) & drain line (150g DT side - 45g GO side) between any of those tanks and dictate whether they are part of my DT system or the growout system. I mainly did that so I can use my growout tanks for frag tanks when I take breaks from breeding clowns.
Anyway, here are the pics ...
