After weeks of pushing it back, I've finally decided to start modifying my overflow box to make room for an emergency drain and durso pipe.
However... The space is very tight and the tank is still full of water. So far I managed to cut away the silicone on the sides using a guitar string. I still have about 3 inches to go, but I can't seem to make it through any further. I also still have to remove the silicone on the bottom.
Any ideas how to do this? Pulling both ends of the string through the drain holes results in it just scraping the glass instead of going through the last bit of silicone. It's quit a thick divider and still barely moves, so I have to cut it all the way through.
