hey,

got a new 90*40*40 fish tank,

after looking at it at home under bright light, noticed about 5 tiny air bubbles, about 1/4mm in diameter that are trapped inside the 10mm glass. Has it on both of the main facades. Quite visible under bright light.

Is that an issue, structural integrity etc? How common is it?? Thanks.
