Bought a 6 month old, gently used tank that was holding water. It's an Aqueon 65 gallon, dim: 36x18x25, glass thickness ~5/16. I've read that this particular tank could have problems leaking if not handled correctly. I've inspected the interior silicone, which looks great, and the seams of the glass. The pics show some areas of the seams that appear to have bubbles. Is this going to be a problem either now or in the near future? I planned to leak test it outside, but determined that I don't have a way to put it on a level surface. I don't want to risk damage, so I'm going to do a short leak test inside my home. I'll do a partial fill and keep adding more water over a period of time. What are your thoughts about the pics? Thanks.
