I finished it up this weekend and it's looking good!
First, I completed the refinishing of the wood. This was a simple sanding and rubbing with tung oil and looks very nice. Then I first filled the tank with water for a day and let it sit and then put the tank in the table and filled it again for a test.

Next, I take care of the light. That's what the tube running down through the tank is for. I use a 12 watt florescent fixture with an aquarium spectrum bulb. I made an acrylic leg to hold it up to the mid-point of the tank and just drop it down inside and fish the cord out through the base.

And we're done! Here it is sitting in our living room with everything running. I put some plants and a couple snails in but haven't bought fish yet. Hope everyone likes it.

PS - Warwagon - I don't remember exactly what the blade is called. I use blades with fairly big teeth but as close to completely flat (no offset between teeth) as possible and run the jigsaw very slowly.
