Bubbles in tank glass

[WhenKeepinItReefGoesWrong]

Hi everyone,

I just received my Waterbox 50.3 AIO, and noticed these two spots with ~5mm wide bubbles on the surface of the glass on the bottom of the tank. They protrude from the surface ~1mm. I've contacted Waterbox support, and they are going to get back to me, but I was wondering if anyone else has experienced this and how much of an issue it could be?

Thanks!

Sometimes glass sheets will have bubbles in them. Most times the tank makers will not use the imperfect area.
Since this was the bottom they assumed it would be covered with sand I guess. I would not worry if they are bubbles that small.
The manufacture should produce a flaw free tank for the price they charge.

I wouldn't pay $600 for a 50 gallon tank with a defect in the glass.

I wouldn’t use it that’s a crack looking for a place to happen
