Got the tank put on the stand to see how it reacted with weight. Empty it did well, but when it was about half full I gave it a little rock and became concerned about its stability. I added the 4 virticle supports that I left out last night which helped to make it truly rock solid. While the tank finished filling i cut and placed the inner floor of the stand and put the 30 Gal. sump in to see what kind of room i would be working with under there. All and all I'm pretty happy with how everything has turned out so far. Thank god for Google SketchUp. Here's how it looks so far.
