So I had a chip in my 180 gallon, I called Aqueon and they gave me another tank because it was under warranty. I get the tank home and now being paranoid because I did not see the chip earlier, I really go over the tank really good and found this bubble in the corner silicone of the tank... It looks like a perfect circle so I was thinking it was a glass spacer but I don't see them on any other corner. What should I do? I have not put water in it yet.
