the tank should be about 84 x 36 x 24(314gal)might be narrower(cant remember off top of my head how wide door is).Looking at an auto tp off tank under the stairs for evapuration,plus a big sump.Frame will be 4x4's,so bowing shouldn't be a prob.Garf calculater said i could use 3/8 glass,but i'll use 1/2 just to be safe(i'd be divorced if the darn thing ever broke!).Top will be solid piece with openings cut out,and the front will be the same.will probaly just buy lighting,me and electricity don't get along
