Polyp Nipper
One of two return pumps are running. The return pump running feeds 3 of the 4 returns to the display tank. The second return pump will feed 1 of the display tank returns and the 2 returns of the frag tank. I do not have enough water to run the frag tank yet 
All of the returns have VCA Random Flow Generators and so far I really like them, they really throw out the flow in a wide rang randomly.
Here is a quick video of the VCA Random Flow Generators, you can see how it break the surface when sending the flow up:

Here is the the system running. I am working on tuning the drains, drilling the locline for a siphon break and keeping the VCA Random Flow Generators low enough so the inductors are not sucking air into the water flow.
