I thought we could concentrate this discussion. I believe that the 30 something gallon stand that Dylan likes is
33 gallon stand
I think its possible to build something like this for a 55 gallon, but it would need to be sturdier. This would be a moderately expensive stand, but require very high skill. If I recall your still a kid. Do you have access to a table saw or skill saw and any knowledge of how to use it? I would really recommend an adult. I use them both fairly often and they still scare me. A cheaper easier stand would be one with a frame and box that looks more like a set of cabinets.
The length and width of your tank and the height off the floor you want the bottom of the tank to start would be excellent info for anyone trying to help you.
