OK so it's a bit less techno-savvy than those of you that have all sorts of specialists products, but I had several nice rocks with a ton of AP on them. I tested my method out the other day on one of the rocks and it worked great. Turned the tap water on as hot as I could get it, and ran the area with the AP under it for 15 secs. It's been back in the tank now for 4 days with no sign of anenome's and the clean up crew is having a field day on that rock eating left over AP parts out of the holes. Not high tech, but it does work with no apparent harm to anything else.
