I've been thinking about building a plywood tank. Before I take the big jump into a big tank I wanted to try my hand at a small tank. I already have a 1.5 quart kit of pond armor. I have an old 75g tank that I'm not using, 1/4" glass. Wouldn't care if I broke it down and cut down the size a little bit. I was wondering what size of plywood tank could I build with that size glass. Was thinking maybe 48"x18"x16", if the glass thickness will work. Any help is appreciated and thank you in advance.
