Since breaking down my 60p a few years ago I've been keeping it dry in my room on carpet in a closet. Is there a better way to preserve the silicone on a fish tank? I actually noticed that when I broke my tank down, there was brown sludge or diatoms growing/seeping half into the silicone. Does this mean the tank is compromised? If that's the case it'll probably just become a vivarium in the future for safety's sake. Kind of upset that the tank only lasted for about 3 years....
