a metal letter opener.....it's great with the point for getting around the corals and the flat edge for scraping large patches. You may want to wear goggles as they squirt sometimes. Just take the rock out of the tank scrape over a towel or 5 gal bucket and put the rock back in the tank or you may choose to rinse it in a bucket of old tank water right after a water change.
