Bubbles in silicone?

[Ryan15236]

When I look at my tank at a certain angle I can see what looks like bubble in silicone. If you look at the seams straight on they look great with no bubbles. Are y’all seeing anything to be concerned about?

Those bubbles are in a straight line within the seam, I often see this on older tanks, as they start to show their age…

I’d just keep an eye on them, and see if they keep growing, or remain constant!

I bought this tank second hand off marketplace. I’m not sure of the age but I’d say it’s been around for a while. I plan to upgrade with our next home upgrade which plans to be within next 1-2 years. Hopefully it will hang in there for me

My LFS has two 180g tanks that came with the business when they bought it 16 years ago… estimated age is 25+ years… they’re exhibiting similar bubbles, albeit more progressed!

I’d take a few nice, focused photos then compare against them periodically to look for signs and rate of bubble formation/growth!
