Thats what i would have typed lol Agreedpcfriedrich;4212967; said:my tank is about 15 years old and its holding up just fine. my only worry would be if the tank has been dry for years and years. I imagine (but could be wrong) that the silicon could dry out. if it does leak, replace the silicon. you got another 20 years of enjoyment. its not like the glass is gonna get old. at least not in our lifetimes.
