Speaking of stand problems, here's an interesting one that I thought I'd fixed.
My tank doesn't touch the stand in the middle because I guess the table top is bowed. I had two pieces of corrugated cardboard under it to squash down on the far sides and stay expanded in the middle, but I took one out while my tank was broken down since I'd added the 2x4 reinforcements and thought now it only needed one. Tonight I'm noticing that it definitely needed that other sheet, but now my tank is full of water and fish, 40+lbs of sand, 20lbs of slate, and numerous other decorations and plants.
What's a good way to get the tank light enough to slide a sheet of cardboard under it without having to break it down again? I know I'm going to have to drain most of the water, and probably get 2 of 3 friends to help lift it, but other than that any ideas on what I can do?
