I found a stand for sale that is advertised as the size for a 40 gallon, at 48" x 19" or so, but I have a 75 gallon tank with a 48"x12" footprint. If a tank will fit on a stand, is it safe to assume that the stand will support it, even if the tank is substantially bigger? The top of the new stand is not solid, so if I had a piece of wood cut to the size of the top of the stand, would it help to spread out the weight of a bigger tank? This stand would look so much nicer than the one my tank came with, which is painfully obviously homemade. Then, when moving the tank onto a new stand, how the heck do you do that? Should I just wait until I move? TIY.
