I am looking at trying my hand at building an aquarium stand. The stand I want to build will hold my 20 and 30 gallon aquariums. I want to put the 20 gallon on bottom and the 30 gallon on top. Has anyone seen anything like this? It does not have to be all nice and fancy but would like it to be functional and able to get into the bottom aquarium. Any links to pics of one would be greatly apprieciated.
