Hydroids - Seriously

[dankolle]

Guys, I am at a total loss. I have been battling hydroids for the past year, and they are winning. Spread to almost every single rock I have in the place. Tried the boiling water, tried everything I can think of and it isn't getting better. I can't remove the rock and boil it 100% because of coral attachments. What should I do? I'm desperate!

You do not want to boil the live rock, especially inside the house. The fumes can be very dangerous.
If you really want to kill the rock soak it in freshwater with a little bleach and afterwards soak in freshwater with a dechlorination product.

Yeah, some guy on RC nearly killed his whole family from the fumes. Especially dangerous when there are zoas and other polyps with palytoxins.
When people say "cook" rock, that's not what they mean!

I have coral attached to rock with hydroids...so I can't boil it anyway, any ideas how to take care of it without bleaching it or burning with a torch?
