That's what I figured. The overlap on the glass is the only thing that is questionable. It's maybe 1/4"-3/16" wide to either side. I feel like I will be okay, just figured i would ask around to see if anyone has had any similar experience.
I had a similar looking situation with a 75g on the two front seams...previous owner seemed to have gotten a little too close to the corners with his scraper. I carefully removed the old silicone with a razor blade and then re-siliconed. Mainly did it for peace of mind...
