question on used 180 silicone

[Genec]

Hi, I need some advice on this used tank I purchased. I read that the silicone that is actually holding and sealing the tank is the silicone between the glass planes. On this tank the silicone on the front panels look worn (probably due to excessive cleaning from the previous owner). The only part that looks worn is the silicone on the front vertical panels. This tank has some sort of frame around the front glass edges (vertical frame) as you can see from the pic, Is this normal for these tanks? The back glass pane doesn't have this and I can see the actual joints for the glass panes. I don't really want to do a re seal or anything and wondering if a water test would suffice. BTW the glass looks to be about 1/2 inch thick.

I have a 180G myself, I bought it new just for a little piece of mind. Now looking at your pics there are some nice chunks missing. I really didnt see any air bubbles thru the seams. So youre probably good.

I cant really see the front panes unless I remove that veritical frame around the front corners. Not sure why it has this and the backside doesn't. The backside looks really good with no air bubbles. I was just a little concerned as some say there needs to be a good outer seal to protect the silicone between the panes and others say its really cosmetic and that the seal is actually between the glass panes. Is it sdafe to say the tank should be fine if the silicone between the glass panes are good?
