get a buddy - you need several feet of braided wire - like sevenstrand wire - take a metal yard stick and push it down in the foam - seperating the foam from the front of the tank - once you get it seperated push the wire down in the gap - have your buddy grab one end and you grab the other end - wrap it aroung a piece of broom handle to grip it and use it like a wire " saw " seperating the foam from the tank. just my two cents worth
