Bubble in seam

[Floyd R Turbo]

I just set up this glass tank after moving everything from an acrylic tank that had a crack:

Now I have noticed this:

I've read plenty about the 'typical AGA silicone job' and I've seen tanks in stores with bubbles in the seams, but does this look like anything to worry about?

I didn't notice it when I set the tank on the stand, but I admit I wasn't really paying attention. I just noticed it this morning before I left for work.

I made the stand myself and the tank was flat and level on it after setting it up (check the tank build thread for description of that effort) but I wonder if the stand settled in a bit under all the weight, because now I can slide a piece of paper between the tank and the stand along the front and side edges that meet up at this corner. I used a ton of screws and gorilla glued all the members and it is really solid.

So honest opinions here. Should I be having a heart attack, again, or is this just a typical AGA seam that I shouldn't worry so much about?

Well after much contemplation and a near aneurysm, I took today off and the guy that helped me move in the first placecame over and helped me tear it down. Thanks to awesomely sound advice from another local club member I went and got a sheet of 3/4" ACS plywood cut for the top of the stand last night, and after the tear down we put that plywood on and shimmed up the edges and set it back up. The bubbles are closing up and a few are actually gone. (crosses fingers)

As it turns out, the stand was not in full contact along the edges (L and R). We carefully shimmed the gap between the plywood and the stand with the tank (empty) on it, and checked for gaps with a piece of paper and it looked good.

The positive side is that I got to re-arrange the tank and it looks much better.
