From one possible tank builder to another, good luck.
I am shortly gonna be building my very own 4'x'4'x2' tank (god knows how many gallons that is). All the sides of my tank will be glass, because I would like to see my aqaurium at any angle.
I'm not yet interested in building a base/cabinet for my tank, but instead lay it out on a raised layer of carpetting.
No disrespect, but I don't understand what you mean by saying the tank plans that you saw having wooden sides. I'm sure it may look nice, but don't see the point in not being able to see my fishes at any angle. Do you mean a glass tank within a wooden cabinet?
