Get a thin guitar string (high E) and run it between the glass. It'll cut the silicone like butter.

When re-doing the tank, run tape about 1/8" from the seam. After you stick the panels together, run a nice bead on the inside of the seams, wet your figure with a bit of soapy water and run it along the seam. This will give you a very clean looking seam and prevent any screw-ups due to the silicone setting. Peel the tape off after it has set a little bit. Now you have pro seams and super clean and straight edges to the silicone.
