My tank and corals are very healthy so I think I'll use caution and not dip. If a problem develops, I can always do it after the fact. I'm just a little nervous cutting into the fleshy polyps of my LPS for the first time. I have micros, lords, echinatas, and various faviid colonies to frag. I'll try a couple first to see how it goes before taking the Dremel to all of them.
