Heres my recent handywork on my 3 gallon.
I Built the tank stand/canopy That also holds a 1.5 fuge. I have a wood panel between the tank and the fuge/equipment, to give it a clean look. Its lit up with 2 13w PCs (50/50). I have a fan venting out the back for heat controll. and a small PH pulling water to the fuge. The fuge is built slightly higher then the tank so I could pipe it just to overflow back to the main tank. I also have the return pipe setup slightly off the surface. That helps to break up the surface tension of the water.
