Fish tank problems

[Trever.H34]

I recently just bought this 180 tank and stripped all the silicone and redid it myself because it was leaking and just recently I saw an air bubble in the new silicone I put in this tank, should I be worried that the silicone won’t hold or that it might blow out? It’s not leaking yet but I don’t want to come home to 180 gallons of water all over my house.. Any ideas to fix this ?

Yikes... You may have to take down the tank and try to reseal it.
Cause yah, you really don't want 180 gallons of anything on the floor

Agree with Rocky. I had 5 gallons on the floor once... Can't imagine 180.

I had just a small bucket spill.... Yah even that is enough

I can't determine where the silicone is or the bubbles. I see a wide hazy area below the black gravel with a narrow white strip just below it. Below that I see what looks like more gravel. I'm guessing the hazy area above is silicone that smeared across the glass and wasn't removed?

At the point of the arrow on your image it looks like the actual silicone bond between the base of the tank and the front glass? If so, I can't make out any bubbles. If you only have a few small bubbles here and there, you're probably OK, but I can't determine anything from your photo.

Definitely reseal it, that is too much water if it does go south

Concur with all other posts. It looks like the seal has gravel or sand it, in addition to the air pocket.

When you reseal the tank you need to spotlessly clean the seam and ensure it is totally dry and chemical residue free before applying the silicone. Do not use any silicone softening materials to help remove the existing silicone, it will affect all the silicone even the stuff you don't remove. There should be no impurities or material in the seal when you are done.

One concern I have with resealed tanks is that the silicone between the glass plates does not get replaced so the inside seal, the one you replaced, is even more important.

On a particularly badly sealed 70 gallon tank I replaced the bottom plastic part, not present on your tank, with pvc corner moldings backed by silicone to provide support from the outside as well. Such as this material except mine was black. https://www.homedepot.ca/product/al...-4-inch-x-8-ft-pvc-exterior-corner/1000421398.
