Getting rid of Palys?

Nonfamous

Reefing newb
Okay, these copper penny palyos are taking over my tank. Any suggestions for killing them off? Seriously!!! They have survived poor water conditions, low temps and even a cooked tank. I'm going to start slowly replacing the rocks covered with them to reduce their numbers. Any other advice?

(Yes, I know they can be poisonous.) What should I do to salvage the rock? Is it worth the trouble? Freeze it? Air dry it for a few months? Bleach it? Bake it?

Any ideas?
 
Do it right. Either outside on a camp stove (best way), or turn your hood fan on high before you put the rock in the boiling water on your stove. Proper ventilation is key.
