I bought this used 125 from one of my lfs last week. I took it home filled it up in my garage to test it just to be sure. Three days later I checked it. I found a small amount of water near a corner when I was looking for the leak I noticed that there was about a 6" long area of silicone between the 2 pieces of glass that was a white milky color. After I emptied the tank if I press on the glass with just 2 fingers the white area grows/gets bigger. Am I righting thinking that the main silicone seal has started to fail? Lfs owner isnt making it easy for me to return the tank. Even if it wasn't leaking I don't feel comfortable setting this tank up in my livingroom. What are your guys thoughts? I have some pics but for some reason they wont upload

I think I would have to take the whole thing apart and replace the silicone between the glass. Total rebuild.

Yeah.... I’d wouldnt trust just resealing the inside. It will need to be rebuilt like mentioned above.

How much did you pay for it if you don’t mind me asking?
I don’t know where you’re from, but I know here if you buy something used there are no guarantees and no returns. Used is always a gamble.

I don't think it needs to be rebuilt, but if you still want to do it then it's your call (though that'd be your best bet). Or you could make 2 plywood tanks out of it so you get 2 tanks :p

Agree. Structural seal has failed. At least the piece of glass would need to be removed and redone. And then will another corner fail?
