Pests migrating from refugium

If you want another tank with rock in it, there's no reason why you can't use this rock after sterilizing it. There's plenty of ways to completely wipe out all life on live-rock, then start with it from scratch. However, starting again with new dry rock will save you all sorts of time and trouble, but I've always wanted to do a bleach and muriatic acid treatment on rock just to see what it's like LOL.
