If there's Bryopsis kill the rock entirely, put it in the freezer for a week and then cook it for a month or two. I've battled that stuff and it is impossible to destroy if you're trying to spare the rock itself.

Any benefit you might see from keeping the bacteria alive is going to be offset by a massive ammonia spike from all the die-off. Kill, cook, celebrate pest-free living!
