Razor blade. Slice it off. You won't be able to get the stuff between the glass, inside the seam, but a new bead should hold it. The downside is, you may have to reseal the entire tank since silicone won't bind to silicone. I would make sure it's leaking first, then if it is, call your tank builder and express your displeasure nicely (flies and honey darlin ) and see what he'll do for you.
