Resealing a tank

[zx1snowman]

Has anyone personally resealed an aquarium or personally know of somebody who has? If so, how long has the reseal held?

I have a 90 gal that leaks at the bottom. The silicon has become lose.

I have watched a lot of videos on you tube on aquarium resealing. I believe I have the Knowledge, Skills and Ability to reseal mine.

I know that all the old silicon must be cleaned off, as silicon will not stick to itself. That is my concern. I read the comments by a couple of people, who said the aquarium needs to be completely disassembled. Because when the tank is resealed, the silicon will not stick to the silicon holding the glass panels together and will leak. Some of the you tube videos said this is not a problem.

I do not want 90 gal of water on my floor and a bunch of dead fish.

I got lucky on this leak. I went to get a drink at 1:30 AM and stepped in some water. I also happened to have a 55 gal set up with one fish.



Thanks for any info,

Depends on the condition of the tank. Most of the the time complete disassembly is not required and new seals will hold a tank for years. If you can see that the silicone between the panels is deteriorating, peeling, falling out in pieces or missing, etc., than you should consider a full rebuild. This usually only happens on very old tanks or if the tank was assembled poorly to begin with.

I have built and rebuilt or resealed dozens of tanks.
If the silicone between the panes of glass is solid you only need to reseal the inside seam to prevent leaks.
Look between the glass if the silicone is opaque or white looking it is loose and not holding a solid bond on the panels.
