As I finally got around to breaking out the camera I took a few choice pictures of my work so far on the tank.
On the right is a picture of the return I made, a (non kink) hose I bought at Nature pet center is clamped to a 3/4 hose attachment and the run through various 3/4 " piping
The flow rate out of it is pretty good, it will be fun to see how much of a current it will make when the tank is full.

On the Left you can see how I have drilled the side of the stand. I bought this cabinet from Ikea and as it has not intended for Aquarium use it has required some "Do it yourself" modifications. I bought a 1 1/2" drill bit and borrowed a drill from Gregg and went to town. I use the upper one for the hose and the lower one as a access port for the various plugs coming from the sump.

This isn't the best picture but shows the 2x4 wood brace I added to the underside of the cabinet. Mark expressed some concern that the cabinet would not be able to hold the 400-500 Lbs of weight from the display tank. I had thought about getting those L metal brackets but opted for the wood brace option instead. The Home depot gut gave me a PERFECT fit, so perfect I didn't need to hold the wood in place when I drilled the screws into it. I was seriously impressed (exactly 96cm in case you cared)
Below you can see the picture of the sump itself in the cabinet. The water level will not be as high as you see it here (this is the water from testing the return.)
The first section is where the water will enter via the hose you see coming down and into the water. The protein skimmer is next to it which uses a process of mixing water and air to draw out organic particles (the particles are attracted to the air bubbles and are carried to the top which then gets collected in a cup.)
The second section will be the Refugium, essentially it is a place for Macro algae to grow and to allow lots of critters a safe place to grow without getting eaten by fish.
The 3 dividers are known as a bubble trap. When the water comes down from the display tank and the protein skimmer is done the water can have many micro bubbles in it. The bubble trap makes the water travel a little further and is designed to allow the bubbles a change to escape out into the air.
The third section has the pump which returns water into the display tank and the return which you saw in the first picture. The pump can handle 600 gallons per hour which sounds like a lot but after pumping water up a meter the rate actually drops to about 350 gallons which is apropriate for a 33 gallon tank.

More pics and info to come, I will have the overflow installed soon which is now glued but I need to cut a pipe so the tanks water level will be higher. Hopefully tonight I will have this done which will allow me to fill the display tank as well and to test the whole water circulation system as a whole.
