A screen driver at the base works. The rock usually can't just scrape off since its semi sift. Once you get part of the base to peel up. You can start keeping all of it. The base itself is usually a little more leather like so if you can get some of it lifted off you can pull it all off. I've done this many times but with the rock out of water. Since its harder to work with it in the tank. If you can get the rock out you can't also turn it upside down to where the nem is barely touching water. Usually itkk release itself to get back into water.
