Just to be clear I just removed the inside seems not the silicone in between the glass. The pic is of the bottom corner of the tank from the short side, and the long (front pane) is viewed from the side (the one thats not wresting on the bottom). I removed the inside seam and it left the gap where the razor blade is.
. Pushed most of it back. I was telling myself the whole time to remember to remove it all as I've heard of other peoples mishaps and as murphy's law would have it, it's on the front viewing window's side.
