I’m getting ready to build one for a 180 gallon and mine is going to be on carpet and was thinking about that very problem and I came up with this, The plan I come up was to make the stand real rigid and put 1” on the top of the frame for the aquarium and 1” one bottom and then use floor tile as shims and put the under the corners that need leveling
