I have a custom 38 gallon tank that is about 20 years old, and I noticed some air bubbles/pockets inside the silicone today, near the top of the tank.
Is this cause for concern? is this the beginning of seam separation, or just something I should keep my eye on?
Here's a macro shot of the entire affected area. (NOTE: Ignore the huge splotch near the top, thats just salt splatter!).
