concerned about seam

[Ackk]

On day 15 running with water after being down for a few years and just noticed this in the seam. Should I be concerned?

Was it there before? It appears you have a plastic trim on top.. any idea the brand of the tank? If it’s Red Sea I’d run but I’ve seen this a lot on aqueon tanks from the factory.. what size is it?

The smaller bubbles are very unusual… have you ever noticed them before? They look like mistakes during manufacturing…

The larger bubbles are more of a concern… have they suddenly appeared since you filled the tank?

I don’t know what those white dots are, is that air bubbles, is that what you think.

Based on the lower half which is solid and dark, could be some separation.

Was it that way when filled or did you just notice that?

I just looked at a photo the day I set it up when it was dry and it was there then too. This is an old boy. 58 gal Oceanic 36 x 18 x 21

If it was there before, and isn’t spreading at all; you can either do a reseal of the interior of that seam, or just leave it and make a mark to monitor for future bubble spread…

I'll put a mark on it. If it gets worse I'll just replace. Its 25+ years old at this point. Thank you
