Question about silicone on my new tank

[Likvor]

Hello,
First post
So two days ago I bought new aquarium and filled it up.
But on the right side there is almost glass on glass(picture attached).
Also glass thickness is 6mm but it has ground edges and there is 3mm that is siliconed on front panel.
Tank is 120 liters (30 gallons), 60x45x45cm.
Should this be cause for concern or not?

Attaching also picture of normal glass joint with silicone.

I don’t think I’m seeing what you’re seeing. I’m not seeing any air bubbles though so I’d believe it should be safe. @kharmaguru @mtnbike101 @MtnDewMan @Timfish any thoughts?

Just quick update:
I have contacted aquarium manufacturer and he assures me that discoloration is due to silicone for that particular vendor. As the coloration for this particular black silicon is not synthetic anymore (apparently because sythetic additives lowers silicone ability to hold more than 300kg per sq cm, which is, in his words, also more than enough) there can be discoloration when bonded with glass.
And that ground edges have nothing to to with structural bond between glass panels. Ground edges have correct amount applied silicone for proper bonding altough it seems that there is no full thickness of glass in joint.

All in all he assures me that, if all parameters for deploying aquarium are correct( leveled stand and aquarium is filled with water and not dry, and not moving aquarium) that silicone and bond should last 10+ years.

From that particular vendor last aquarium lasted 9 years(from 2013).

And yes, I am aware that leaks can happen anytime, I was just paranoid that front glass won't fall off or explode like on youtube.

Zero problem IMO. The right seam is just a thinner layer of silicone between the panes than the left seam and happens all the time. I guarantee the entire bottom of the tank (that you would have to flip the tank to see) looks like that from the weight of the side panes squeezing the silicone out. The silicone is still there and doing it's job.

If your pictures are each from the same angle, just different sides of the tank, I would have contacted the manufacturer as well. I'm used to seeing a bead of silicone in between the two panes. However, I'm going off of my 100g tank. Historically, most of my tanks have been acrylic.

I see your concern. Looks like a solid seal, no bubbles. But it is a very blue picture, not clear and crisp to really see what it looks like.

Ok, here are pictures without blue light. On left side there are visible bubbles in silicone. This is new...

I think it's fine, I think it's the way the glass panes are placed from the sides vs from the front or a mix of both.
