Should I be concerned about this crack / scratch?

Hi R2R,

Bought the Innovative Marine Nuvo 20 Fusion a while back from Bulk Reef Supply. I cannot tell if it is a scratch or crack in the glass, but it doesn't appear to penetrate beyond the surface when I look through the side of the glass. For reference, it is probably roughly an inch long. I am not sure if I should be overly concerned...

Side shot, which doesn't offer much use to me, but maybe you can see something alarming.

Thanks for your time!

Looks like a scratch to me.

Scratch, not to worry.
