removing items siliconed to glass

[turbovr6]

Hello all,
I need to seal a leak in my tank, I posted this a few posts previous,,,,,

Anyway, my tank has an internal filterbox siliconed to the sides and bottom. I need to get this out to re-seal the leaky seam. What is the best way to get the silicone to release without breaking the glass?

Thanks in advance

Remove all the visible silicone with a razor blade, to begin. Once the filet is removed, get some monofilament fishing line and work it down the seam to cut the silicone in the joint. Use it like a saw. It's sort of like flossing your teeth. This should seperate the filterbox from the tank.

sounds like a good idea, lucky for me I have plenty of fishing line Thanks

or just run the blade down into the join as well, the join will pull apart with little force.

Just remember that you have to get the joint 100% free of silicone before you resilicone it. Silicone doesn't stick NEARLY as well to itself as it does to glass. (bad experience siliconing bathtub)
