Glass Aquarium

[Treed]

Wasnt really sure where to post this but maybe someone will see this and have an idea. My friend has a 500 gallon aquarium and I took this picture of his tank because I had a tank in the past that did the same thing so I got rid of it. But I also had just got a brand new marineland tank with stand and its doing the same thing. Both his tank and mine are perfectly level so I really have no other idea why its happening. His tank is 3 years old and mines not even a year yet. But here is the picture let me know if anyone has an idea or tips to make sure all the water doesnt come rushing out of the tank! Thanks!
And this is a shot looking into the front pannel of the tank.

You see that in tank silicone seams all the time. I wouldn't worry about it. Probably has been there since it was made.

Is it something that has ben always there, or something that was never there and progressing. If it was the latter I'd be concerned, no idea why it could be doing that. i would contact the tank manufacturer. If it has always been there and is staying the same, I would not be worried since there is plenty of silicone still sealing it and it was proabably just a place it did not adhere well. Mine has a large bubble in one seam.

k in both tanks it seems to have just showed up. But that makes me feel better that its not caused any problems for anyone.

+1. but I will keep my eyes peeled on this. I do manufacture tanks and when something like that occurs I redo all the silicone-work.

I've seen similar marks just appear when filling a tank for the first time but never increased afterwards is that a sign of anything or just the silicone shaping up with pressure???
