Hey all I have a new 55g that I am trying to level with a carpenter's level. It's showing that it's back heavy or my floor just leans that way. What should I use underneath the stand to level it more? I feel like wood might split or be too weak but I just don't know. What have you guys used in the past?

Metal shims.

Level it first dry, then again after several days standing full of water.
