I use medi-coral dip (Iodine Dip, for pests) but Revive seems to be the more popular, softer choice. I have temporarily adopted a receding Lobo from my brother to try and dip it, feed it and hopefully bring it back, as it was a lovely piece.
I dip EVERYTHING before it goes into my tank. I've seen countless little pesties fall off into the liquid and am thankful that it's part of my process.
