Is your tank level? They can crack if they aren't.

I can't tell where the crack is in your picture. It will be hard to tell either way. If it was me, I would just replace it, unless I could determine that it was only a scratch. I wouldn't want to risk my tank, or my floors for that matter, with a crack.
