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.
