Hi all. I've been looking around at this forum and others for a few weeks now, and have just recently bought a 29 gallon for a community tank set up.
I originally had the tank on a desk that is built in to my bedroom wall, but the desk got very flimsy with the tank full, so I emptied it and looked for another place to put it. I'm trying to do things as inexpensive as possible, and didn't want to spend 200 dollars for a good stand, nor did I want a cheaper Wal-Mart one because they're made of particleboard. I looked in to getting a metal stand, but the floor is carpet so I was worried about stability. I eventually settled on making one, but I don't have enough confidence in my wood working skills to be able to construct something that can hold 300+ pounds. I came across a few threads where I saw people using cinder blocks and wood planks and thought "now there's something I can do." I went to Lowe's today and for $25 came up with this:


It's just normal 16x8x8 cinder blocks stacked two high with two 2x10's on top, then three more blocks spaced evenly with 2 more 2x10's on top to support the tank. It's not the prettiest thing in the world, but it's not like it's in the middle of the living room, plus it's very stable. The only issue now is leveling, the stand itself is level, but the tank is not. I put some foam board under the tank before placing it on the 2x10's as I've read that this can help, but it's still not perfectly level. I was hoping some more experienced members could let me know if this is level enough to prevent a blow out, and if it isn't, maybe suggest some ways to fix it. I know that shims will work, but I wasn't sure if I should go that route because the stand itself is dead level. Is my problem being caused by the foam? If so will this correct itself? Here's a picture of the level, sorry for the quality, my camera is cheap and doesn't have a manual focus. (As you can see, it was focusing on the wall behind the tank instead of the level)

Thanks in advance for any help anyone can give me.
