I'm thinking about putting a 125G tank on my stairs--on a landing midway up my stairs to be precise. My contractor says the stairs will hold the weight, no problem . My plan is to build the tank stand so that it spans two steps on the landing. Basically, I have a landing that is comprised of two 40"X40" stair steps, one about eight inches higher (one step) than the other. I think I can build a stand with 4 long 4x4s on one end and 4 eight-inch shorter 4x4s on the other. If the top is all tied together, and I tie the bottom of the shorter side to the longer legs, is there any reason this wouldn't work? Am I trying to talk myself into something crazy? Anyone ever see or try something like this?
