Soldering iron!! What a great idea.
I've heard of people having some minor success epoxying over hydroids, but in my case, they just grew over the epoxy. Yay. Blowtorch, soldering iron ..if the rock is structural and can't be removed maybe boiling water in a syringe? (I've had some minor success zapping valonia and bryopsis with that trick)..
