I have heard that when silicone starts turning white it is looseing its Adhesion(?) to the glass and potential for a seal failure is higher. My 125g was built in 1983 I am pretty sure the silicone is still the original silicone from the manufacturer. It has a bit of white discoloration in the corners at this point should I be concerned?
