Air bubble in glass pane. Is it dangerous?
 

I was cleaning my glass today and noticed a tiny bubble on the front glass. Smaller than an oxygen bubble. So I tried to wipe it off when I noticed it is inside the glass. Could this be a weak point that could lead to the pane cracking?

I have only had the tank running 3 weeks and bought it used without any scratch at all. It could be that this was always there or that it just happened.

My main concern is could it lead to a crack? Both sides inside and outside are smooth so this is in the glass.

some sort of hiccup in the manufacturing process would be my guess. i cant see it being much of an issue unless it was experiencing rapid and extreme temperature changes...

Great thanks.

Sometimes referred to as a 'seed'. Its definitely a defect in the glass manufacturing. Unless it is huge... it shouldnt be an issue!

About the size of a tiny air bubble. Smaller than the head of a pin.

I wouldn't worry about it.
