Stand will be getting reinforced friday morning yet again LOL. Only reason I didn't do a metal/steel stand was due to the height I wanted the stand needed to be built in place and I wanted to finish it off with wood, even though I could have I guess against metal. From research, opinions and facts I have read.. If you take 2.. 2X4s and screw them together and compare strength to a 4X4 of the same wood its supposed to be roughly 30-40% stronger and is much less likely to bow. I used 4X4 on my other tank stand for only a 220 and they actually started to bow or bend with just time and nothing to do with the actual weight
