Mine is dead level in all directions - made sure it was. Remember to shim under the cabinet rather than under the tank.

the 4 foot one is about 5mm out, so not bad at all.

I cracked the 100 usg just trying to force a filter in. I is ok, but I understand that it is an important issue. My 60 usg on the porch with the goldie slants forward with the porch drain slant. This thread has me thinking about shimming it. It is at least an inch drop from back to front--maybe more.
Nothing to be done, i suppose, it's an old house.
