In the distant
future I would like to build my own tank. With the current dimensions of 3' by 3' by 1.5', it would be about 100g. My research tells me that building a 1/2" thick glass tank with a plywood bottom would work out well, a little over $150, which is A LOT less than any new tank I've seen thus far. Most stores/online go over $400 for the tank alone. I've looked at used tanks (not that I expect them to be around in ten years) and they at least want $200 for the tank alone. AND YET google has told me it is not economical to build my own tank, stand, or anything really.
WHAT AM I MISSING?
