Resealing Aquarium

[Wildblue4]

I posted this in another area but wasn’t sure it was the best place.

This new aquarium is an Marineland 250. I filled it up for the first time outside and it has a few small leaks at the bottom. I drained it and after looking real close I can see the caulk is split in a few places. It sat outside all winter in a garage. The caulk looks like it may not be 100% silicone. I bought it used. I have watched a lot of videos about resealing aquariums.
Has anyone done this by just sealing the seams inside the aquarium on one this large? Is it worth fixing and having confidence it won’t leak a few months from now? The tank runs about 2200$ so I would like to reseal it if it will work. Any suggestions?

The generally recommended way to do it is to disassemble the tank by removing all of the silicone and separating all of the glass and then reassemble it (yes, I have done this). If this is your first time then you might want to have someone who is done it before (a company or another person) help you with the process. Good luck with whatever direction you decide to go!

Ipinion: A patch job is just that, a patch job. Might hold for a while until it can be fixed properly. I would not bet the bank on it holding for very long.
It can be fixed as long as its not cracked. @Peace River said it above

I have cleaned all of the caulk off inside the tank. I’m just not sure I could disassemble the aquarium by myself because of the size and weight. I’m sure I could get it apart but getting it back together im not so sure of. I may try my local glass company and see if they would have any interest in the project.

IME, glass companies don't want deal with the potential liability, but you may find someone who works there that will do it on the side. Good luck!

I did do a reseal job on a 29 gallon. It was a hamster tank and they clawed up the silicone. I bladed it out resealed it . It lasted for about 2-3 years and I came home from work and a seam had begun to separate ( leaking ) . So I won’t trust a reseal job again. It’s the silicone between the glass that is most important.
