My tank sprung a leak, can i silicone overtop of seam to fix it?

Bowfronts are notorious for failing. A bit late to this party but I'll throw in my $0.02 anyhow: reseal the tank is pretty much your only option, but also look at your stand and see if there's any way to beef it up, recheck the levelness, etc. because of the bowfront's tendency to spring leaks down the road -any tiny wobble is going to stress those seams and potentially cause another leak down the road.

As for resealing, I've never done this either, but from what I understand, you just cut away the exposed silicone. You don't need to pull the glass apart - just cut the old silicone, clean the glass as best as humanly possible so that the new silicone is adhering to glass and not a thin film of old silicone, and the rebead the corners.

I don't think you need to worry about the black trim on top. Just the corner seams and the bottom panel seams.

(I think, anyhow. Good luck!)
