My sister and I are setting up my old 30 long on the sideboard in her kitchen. We have checked the level of the sideboard with a six-foot level and found we need to adjust the right end up a tad and the back just a tad as well. Then I placed the level across the length of the sideboard and found that it's bowed just the tiniest amount, just enough to let me see a sliver of the wall behind the sideboard. It's a heavy, sturdy piece of furniture of solid wood, but she got it at a yard sale and has no idea how old it is. I don't know if there's any way to tell whether the whole sideboard is slowly splaying out or if it's just a slight warp in the tabletop. Should we be fine if we level the tank and place some 3/8" neoprene under the tank, or might we cause the sideboard to slowly but surely bow more? There's no other surface for the tank to live on, and I don't really see anywhere to put a stand long enough. I'm stressing out and she's so excited about her fish she doesn't want to listen to my concerns... I was already anxious after cleaning it out and discovering the dozens of scratches that my turtle inflicted all around the bottom of the walls of the tank, which she has also chosen to not be concerned about, and I think I'm about to kill someone.... >_<
