Advice on resealing needed

[DopamineKata]

I purchased a used 100g tank that needs resealed which shouldn't be a big deal. It has euro bracing on the top and some sort of extra glass border around the inside of the bottom,that I think is just there to protect the corners down there. Since I don't know what it is called it's hard to find any info on it.

After (mostly) cleaning the tank and blacking out the bottom it became clear that salt and crud had creeped in between that bottom border and the bottom of the tank. I think I should remove that border and clean all the crud, seal the tank, then put that back in place and seal around it but I'm not sure if it's safe to remove it without damaging the tank...

Any ideas / suggestions on how to deal with this?

Tuff question id almost say that they may have been added to stop a leak. Removing can proof difficult but not impossible. Looks like they were added after the tank was made. Judging from what looks like black silicone. If I were you I'd leave everything in place, pickup a silicone/caulk removal tool and scrap all the edges and corners. Then razor blade them to remove as much as possible. And reseal the heck out of it. Should be good for another 20 years after that, good luck!

Yeah, I'm pretty sure both that and the euro bracing were added by the original owner after purchase. The euro bracing has silicone all over the outside of the bracing and partway down the tank.

I'm just worried that if I don't get the crud out from between them it will cause issues.

Its a tuff one when the seem leaks as it has to be disassembled and then resealed alot of the time. I read somewhere that the majority of the strength in the from the seal is the part in between the the glass panes and not the bead of silicone in the corner. If that makes sense,

from the seal is the part in between the the glass

yep... the others are just "decorative" from what i have read also.

Yea pretty simple on a rimless tank but not so simple on a tank with rims.

It's actually clear silicone. It just looks black because the entire bottom is black and there's a narrow gap where the salt hasn't creeped all the way to the edge.
