Ok, well, i still need silicone. It's the frame on the bottom of the tank that's starting to become unattached. The inside is still sealed, but the water is leaking out somehow. I'll just silicone the bottom, wait a few days, add water till it's half way full, leave it for a day or two, then see if it leaks. If it still leaks, I'll post here, but if it doesn't then I'm setting the tank up again.
