I've had a 10 gallon tank for over a decade now, and it has started to leak. I have a bit of silicone, which may still be good.
Trouble is, I have no idea where the leak is, or exactly how to go about sealing it. Since the tank's so scratched up and such, I'm wondering if it's even worth saving, but I thought I'd try to find out how to do it before I threw in the towel.
