I was wondering if anyone has ever done a triple 20g long stand out of wood before. I was thinking of building one myself. I've already done a simple single stand for my 29g but to save space but I was thinking of a stand for three tanks, at least the two lower would be to house 20g longs, and the top could be either a 20 or 29. With all that weight I don't mind using 4X4s or doubling 2X4s for the main support beams. Or should I just find a metal one?
