I just purchased a 120 Oceanic Tech.  Tank is at least 7 years old with black silicon seals.  The black silicon is turning orange in several places - at least 50% of the bottom seals.  And by seals, I do not mean the seals between the two pieces of glass, so much as the "filler" silicone on the seam - the transition between one piece to the other.   
Should I reseal this tank before getting it up operational.
Who would you recommend to do such as task and do they do house calls?
