Weird bubble/shadow in glass

[Coopkid94]

Hi guys, just picked up a used red sea 200xl g2. I slightly nipped the very top of the bevelled edge on the back pane of glass. After inspecting it there’s no cracks that I can see but I have nibbled the bevelled edge a-bit . sort of looks like a very tiny chip. Now I don’t know if this weird bubble shadow was there before or occurred after the damage but I haven’t seen anything like this before? Any ideas would be greatly appreciated as it’s doing my head in.

Looks like you bumped the edge. Sometimes the tank is still okay but from what I can see I can not tell if it is just a minor chip or something?
Bummer for sure.

I have no idea myself I definitely hit the small bevel edge but it just looks chipped a tiny bit. I have no idea what the bubble looking thing is tho maybe a reflection of some kind?

Get a Diamond Hand Pad from Amazon, about $16, and sand it to get rid of the Edges, so it won’t Travel.
