I'm up at 2am because I'm in a panic about building a stand for my 30G long tank. I have it in my head that I'd like this stand to be 33" high, and now I'm in a cold sweat because I worry about how top-heavy this might be. I understand how the sides of the tank need to be sitting on the weight-bearing walls (or frame), and that the whole thing needs to be perfectly level, and I'm planning for my base to be an inch wider all around, but this stand will be on carpet, and well, I'm worried. Any advice, suggestions, warnings, resources for building my own stand? I don't like the store stands because they're way too short.
