Uneven Glass on Aquarium?

[danajs]

I have a Juwel Lido 120 (probably around 6 months max old) and I’ve noticed on the left side that the glass doesn’t sit flush, it’s out by 1-2mm. The bottom is as it should be.

I’ve been out and about today and although I couldn’t get a good enough look at another Lido, I noticed this seems to be the case on a lot of the Rio tanks.

Has anyone experienced this? Should I be concerned?

As long as the silicone looks good and the gap is filled. I don't think it's a problem.
