I just brought my stand in for the first time last night and I now know how un even my floor really is. One corner sits about a 1/8th of an inch off the ground and another one just hovers. The tank is a 80 gal rimless so I want to get this right. 4 foot long stand. Do I shim the tank and level it out that way or should I get some heavy duty feet and level it that way then maybe back it up with a few shims just in case I loose a foot? I tired to look though other threads and there's mixed answers but it seems like allot just go with the shims. Just want to make sure I do it right so I don't tweet the tank or the stand.
