I've now built my stand for my 6x2x2 glass tank. I've overcooked it somewhat which is what i'd rather do for peace of mind. I've used joeys design where he uses 2x4's throughout his build. However when it came to putting in the actual support struts i used 2x6's instead. So i have ten 2x6's as my supports (2 in each corner and 2 in the middle). It's worth noting that the dimensions of my 2x4 and 2x6 are pretty much 2x4 and 2x6, hardly any shrinkage at all. Are there any clever clogs out there who can do the maths. It would be most reassuring to know.
