Check it out. Latest project is a custom 55 gallon acrylic walk around tank. I wanted to design a tank with no cords, wires or pumps hanging in site. I also wanted to be able to walk 360 degrees around it and see the reef. I bought a 55 gal hex and got to work building a stand and hood out of wood and a 35 gal sump out of a leaf bin. I drilled a hold in the center of the tank and hid the flow returns in the intake pipe. I'm still working on building the rest of the reef to hide the pipe but you should get a pretty good idea. Here's some pics.
