Air bubbles inside the glass aquarium seam.

I was doing water change when I noticed all the sides seam got air bubbles inside, some are small and some are big. I also noticed that there are minor cracks at the corner of the black plastic bracing.

I don't recall seeing the air bubbles or bracing crack when I first filled the tank. I inspected my brand new 150 gal tank and I noticed it also got a few air bubbles at the seam, so is this normal ?

This is a 200 gal tank made by Visio, 2 bracing double glass on each side of the top. I been using it for about 2 weeks now.

So you guys think ?

Bubbles are like a time bomb with acrylics not sure if that would be the same for glass.

if there are a few I am not worry about it, but on 1 side there are about 10-15 small bubbles in a 5-7" height area.
