I've got a Q for all those that have built their own stands from this plan. I too have built my own stand for a 80gal tank. Now Im starting my build for my 180gal 6'x2'x2'. Problem I have is that I can't seem to find any straight 2x8s. I thought I had some. Starting building the top frame and bam! Warped! So warped that after I tied one side together, I tried to tie the other side up and the first end kicked up 2". So I was unable to get them to line up and be planar. So I'm ****ED!!! But now I'm thinking to just use 2x4s and add a center leg. It seems to be easier to find straight 2x4s than it is to find straight 2x8s. I'm also thinking I might like the extra access height wise using the 2x4s. That might be worth the extra middle leg. Sump is a 60 gal, so access shouldn't be an issue. What would you guys do? 2x8s no center leg, or 2x4s with center leg? It's gonna be a pain in the A$$ to find straight 2x8s. But it migh be worth it in the long run.
