So I have had the same tank for 7 years now. Its a great tank and I am really enjoying it. But, today I noticed that the front and back pane are slanted ever so slightly in the front direction. The slant is not caused by my floor, my floor is slanted slightly too, but my floor is slanted in a different direction to the two panes. Its a TINY slant, but enough to get me worried.
So my question is, what do I do in this situation?
