My brother's 125g tank recently burst a seam. It was less than 6 months old, so he's getting a new one for free. He offered to give it to me provided I pay to get it here. How hard is it likely to be to reseal this tank so that it will be trustworthy? None of the supports/braces are damaged, it was just a silicone seam that failed, I believe.

Update: The seal gave out in the bottom front left corner (or near there). I'm hoping that all it will require is a re-siliconing. Any idea's/opinions?
 
Just take the whole thing apart and reseal the whole thing. The hardest part is gettting the top and bottom braces off. Once that is done, it is smooth sailing from there.
 
Awsome of your brother to just give you the old tank. Sounds like a great deal to me! There are quite a few experts on here that will give you the best answers to re-sealing this very nice Aquarium. I see the bottm of the tank as the most difficult place to try to re-seal, but at the same time I would probably just silicone the inside of the seam with several coats of silicone and turn the tank so that this would be on the back side (so I would not have to worry about it being a very neat re-seal). basically, I am good at giving bad advice. Still, I try what is fast an easy first. If the seal seems good enough in the garage, then in a few months I would trust it in my house.

I know you will get better advice so consideer this a BUMP!

i got a 125 that did the same thing from a guy on clist DO NOT TAKE IT ALL THE WAY APART just strip out the old silicon on the inside dont go between the glass at all. clean all the seams with rubbing alcohol and tape off the seams so the new silicon dosent go all over the glass then re do the seams and pull the tape off. give it at leat 48 - 72 hrs to set and test it out. Thats what i did and still no leaks. I used all glass silicon cost more but i know its good stuff
 
It's an all-glass aquarium. I'm probably just going to scrape out the silicone inside the tank and redo it. I did the same thing with a 55g tank that I turned into a sump, and it hasn't leaked a drop since.

The problem with turning the tank around to hide a bad silicone job is that its got dual overflows on the back wall of the tank.

When I get this tank redone and set up, its probably going to be set at the end of my other 125g tank in an L shape in my living room, meaning people will be able to see it from all four sides. I'll probably just cover the back of the overflows so you can't see inside it. I've got a 30g sitting empty I can use as the sump, unless that would be too small?
