Hey Guys and Gals,
I was wondering if black or clear silicone goes bad after a certain amount of time. I bought a brand new 120gal Oceanic Ultimate Series RR tank with black silicone. The store had the tank for a few years but never filled it with water. My question is if the tank was never filled and stored in an aquarium store for a certain time period, will the silicone go bad? I've also read pros and cons for black silicone and clear. Is one better then the other?

Thanks ...
