Frankly, Spiker, you have to figure: you can dip it, losing the tiny hitchhikers, but keeping the coral safe---'travel on what they eat'---so if there's any rock in your lot likely to have a predator for this particular coral, it's this particular rock! Dip this one, and the rest of your rock is likely safe. Don't dip ALL your rock. You want the rest of the random surprises. Just not the ones associated with THIS rock, because that little bit of coral (where predators will home in) is what you want to protect. You can also set up a tank with only one small piece of live rock, and all the rest base rock: takes 8 weeks to cycle, usually, and has much less variety once it does, but boy! is it cheaper!
