Glass aquarium seams look iffy

[jkapit]

I am in the process of rebuilding my 175 bowfront aquarium and notice what looks to me like the silicon in the tank seams are starting to deteriorate. PLease take a look at the photos and let me know your thoughts and if there is a way to repair it. The tank is empty right now and is about 12 years old. The pictures are from the front edges of the tank. Since this is a bowfront I am not sure if this is an optical illusion, but posting for some opinions.


Thanks,

Did it sit dry at all?

I just emptied it out over the weekend and is dry now. It was not leaking, but curious about how the seams look.

I was looking on-line for tutorials and saw a method where you remove the silicon from the inside except you don't remove the silicon from between the glass in the joint. I know some of the deterioration is between the glass in the joint. JUst wondering if by just removing the glue inside would be enough. That way it would prevent further salt water getting in the joints.

Did you just replace inside the tank or in the seam/joint?

Just the inside silicon is good enough, you can get reef safe silicon from Home Depot or Lows...GE 1 if I'm not mistaken is the one you need.
