This stand will accommodate a 29-40 gal tank. Almost finished, just need to add a bit more trim around the door and change the handle. 2x4 frame with 1/2" oak panels. The top is paint grade pine, sanded and stained with 2 coats of clear poly for waterproofing. I'm going to make a canopy and then start on a stand for my 55 gal. Cost approx $90-$100.
