Question about tank seam.

[Ravens243]

Good afternoon, I have had this tank sitting around for about a year and I'm about to set it up. Low and behold I was messing with it and noticed the seams on the bottom corners are cloudy. When I push on it you can see it pushes together because it gets darker. When I bought it, it was an in wall display and some other guy bought the live stock because I didn't want it all. It's a 180 gallon so I'm trying to be cautious. Any advice would be appreciated.

If the silicone is changing color with pressure, then its not a solid joint. Also, its at the bottom of the tank so greater weight of water pressure on it. I think you are just asking for a major (and 180g of water is super major) problem. Resealing between panes of glass is a pretty big undertaking.

If nothing else, fill with water (in a garage) and see if it will hold for a week.

The silicone is definitely changing color with pressure. I also think I'm asking for a major problem but I'm also a paranoid person. Thanks for the input.

I would do a major water test on it. If it's stressed like that then their is a good chance it will pop. Would be better off to do it now then in your living room. I would actually fill it up and put some powerheads in it to get the water moving to really check it well. Last thing you need is a catastrophic failure once you have livestock in it
