I will head to Home Hardware to see if I can find the silicone that Fragit Dan suggested.

A few of you mentioned replacing the tank. Why? Are repairs not successful?

Yes, multiple attempts at sealing the leak before I got a dry tank. As mentioned by others, silicone does not stick to cured silicone so you need to cut a lot out and make sure the surfaces are really clean. +1 on the comments regarding the other seams potentially being ready to go as well. I had a stand go on a 75G FOWLR tank in 1997... final insurance tally was $66K. I would expect more than four years out of a tank so there might be other issues with it. If a leak isn't going to cause a lot of damage to your house you might want to risk it, but perhaps not. The tanks I have resealed are on a cement floor in my basement so no real risk to damage the house,
