I have had no luck finding the size tank I want and recently got a 5.5 gallon tank. Anyway, I was wondering if anybody knows a good way to get the silicone off and dissasemble the tank so that I can cut it down to size. I tried using a blade on a smaller tank and ended up destroying it. If nobody has any ideas can somebody tell me where I can just buy a cube no more than 10x10X10 or even a little smaller. Thanks for the help.
