Potential weakness in aquarium structure

[Atlanta Reef]

I need an expert. I have a 60g innovative marine shallow reef AIO. It's ~6months old My wife pointed out that there is a ripple in the acrylic between the display and the back, see attached.

Is this a problem? Seems like it
How big of a problem?
I have a 20g QT tank that I just finished setting up. Do I need to move fish into there?

Thank you for any help!

I’ll bet you’re good. If anything happens to that back wall, it’s still an AIO. A baffle separating the different filter chambers could have been cut a 1/16” too big and the manufacturer didn’t catch it. But your call. Good luck.
