WELCOM TO THE FORUM!! EXCELLENT ADVICE FROM ABOVE BY THE WAY.

Welcome to the forum.

Personally, I'd strip away the whole bead... maybe the whole tank. I did it with an old 150 that I got from Reeladdiction. Was a pain in the rear, but I wouldn't be able to sleep otherwise. 155 gallons being released into your house is catastrophic.

Spilling a 5-gallon bucket is bad - spilling 31 is serious damage to your home.

I find it hard to believe that you have a hair dryer, Sam

Just get a razor blade and cut through the silicone at right angles to the glass 6" on either side of the leak. Then align the blade flat against the glass and cut down and into the silicone where the glass meets from the bottom, do the same thing from the bottom cutting in toward the side of the tank and you can pull out the whole damaged section pretty much in one piece. Go back over it again with the blade to get as much of the old silicone off as possible. Then make sure it's dry (a few minutes with a hair dryer is usually all you need) and you're good to go. Can generally buy a tube of aquarium sealant at any hardware store but just about any clear silicone will do.

Do it right - literally an extra few minutes eliminates all the worry.
