Silicone sticking out of edges of new glass tank? Also how to properly inspect

[creator]

Hi all

I was wondering how to go about inspecting a new glass tank before purchasing it. I know to check the seams, check for chips, scratches etc- but what exactly am I looking for? Is there anything that may seem like something small, but could end up being serious I should be looking to check for? Also, if silicone is coming out of the edges on the outside is this safe/ normal? If there are bubbles in the silicone is this normal/safe?

Thank you

Bubbles in the joints between seams could lead to a leak later. Silicone protruding past glass face on outside is not an issue. You can just cut if off with a sharp razor blade if it bothers you.

You definitely don't want to see pockets or air bubbles in the silicone those are weak spots

What about overlapping silicone? I will attach a pic in a second

And this part - it looks like there are bubbles but not sure

most mass produced tanks will look this way, the last 2 pics look like normal variances, 1st one for sure, hard to tell on second.
