Glass cracks

[cbrynolf]

I have a 55g and just notice some hair line cracks(scratches). I stock my algea scrapper in there and could feel the cracks as I move the algae scrapper across them. 2 are about 3 inches long and one is about 2 inches all are concentrated in one area about 4-5 inches off the bottom. I just noticed them and really have no idea how long they have been there.
Should I be concerned????

It's probably tempered so if it structurally damages the pane, it will burst into 1000 tiny pieces.

Are they scratches on the inside of the glass or can you feel them on the outside of the glass as well???

They are definitely only on the inside and are hair line only. The only thing I can think of is maybe I scratched the inside with my algea scrapper.

It only takes once. I don't even get close to the bed with mine, and use a razor for the rest.
