Is there maybe a tek on this? Thanks!
I'm sure you'll get lots of support on doing this. You don't have to remove all the old silicone, but with a razor you carefully cut away as much of the old stuff as you can, without cutting into the actual seal. Buy aquarium safe silicone, and it has directions on the package. It's not hard, and is worth considering if the tank is that old. If not, I wouldn't bother doing it if it holds water.
