Tank seam question

[1fishkeeper]

Ok I got a quick question for all of the experts and people who think they are experts. My 200 gallon tank got taken down and put in storage for the last 4 years. I was thinking about getting it set up again but while looking at it I noticed this air bubbles or that’s what I think they are. Would you trust this seam? I remember it had some when I first got it and sent the manufacture a picture and they said it was fine.

That will never come apart in my opinion so a seam separation would be unlikely to me. It had to have always been like that. The inner seal is hard to judge however and it being good goes a long way to preventing a leak. Many people just remove and replace the inner seal on an older tank (if it's chewed up or algae has gotten under it) and never have a problem. I've said it before though, it comes down to whether you can sleep at night or not. I guarantee someone else will tell you it's an accident waiting to happen.
