[FishyFishy!]

I have been battling Byropsis on a few of my favorite pieces of rock for about a year now. Kent M works for a bit, but never destroy's it all, and it always comes back.

Since I'm just keeping the rocks live for my new build, I'm wondering what's the best way to get rid of it completely? I've heard putting it in the freezer could work. But I want to make sure. I'm worried that I'll do something, think it's gone and then have an outbreak in my new tank.

I would hate to cook the rock because it is so beautiful and full of coraline. Any suggestions?
