Does my tank need resealed?

[Dythomas11]

Recently purchased a tank that was setup built in wall. No issues/leaks as I helped take the tank down. After getting it home and all cleaned up I’ve noticed the previous owner must’ve gotten a little aggressive with the scrapper towards the silicone.

I don’t have a great picture but you can sort of see below. Is this a disaster waiting to happen if I set it up like this or just visual? It is only on the two front vertical seams. As I said no leaking issues when previously set up. I know new silicone won’t stick to old, so am I looking at a complete reseal?

Thanks for any input/advice!

The corner silicone isn't structural at all. As long as the seal between panes is good the aquarium won't leak.
