Will this be a problem?

Was getting ready to set up a marineland 150dd glass is either 3/8 or 1/2. I bought it used and it had just finished draining when I showed up. Look what I found.

That is the silicone not cracked glass.

Having piece of mind that my aquarium can hold the weight of the water is mucho important to me. This would be in the back of my head always and I'd be worries to come home to a mass body of water on the floor. Just my 2 cents but on the bright side it doesn't looked cracked.

I would Reseal the entire seAm OR at minimum, clean area good with alcohol and apply an even/clean bead of silicone

 

[Silent]

Its not a crack. On the bright side this is not rimless. Not a chance Im gonna take it apart and reseal. I was going to tape off the siliconed areas and reapply some so it looks cleaner as it is pretty rough, but this sucks.

How deep is that imperfection below the water surface?

 

[Silent]

4.5-7 inch below top of glass. So in the top 1/3 third of tank.

Better spot than -16” from surface. The pressure at that shallow depth would make me less concerned but I’d fill it outside with fresh water to see if it’s leaking from that spot.

If you don’t have a leak I wouldn’t worry too much and I would not add any seal on top of the funky spot. An add would not add any real strength to the seam just a blob of sealant to highlight the problem.

Hope it doesn’t leak!

I just dont want water to start to fill in that area if I dont put some sealant on it.

Adding sealant won't do anything. In order to replace/repair the silicone, you have to completely strip all of the old silicone off, clean the glass with alcohol and redo everything. New silicone will not bond well to old silicone...it would be a waste of time imo.

Hard to say by the pic, but that seam looks pretty compromised.
If it's not in between the 2 panes you could get away with a corner reseal, but it looks to me to be between the panes - yes, no?
I had a factory tank with a very small bubble near the bottom of a seam and it started to sweat at 3 years old. Never would have even known the bubble was there if it didn't leak.

It's hard to tell if the silicone between the panes is compromised. If it's not, I would not lose any sleep over it. The inner filets of silicone are purely ornamental. They do nothing whatsoever to augment the actual seal. I'd leave them be, or perhaps even trim them down a little to make them look nicer. Adding silicone on top of what is already there probably won't turn out very well. Removing what is there to put in a new bead is way too much like work.
