Dont freshwater dip your acro's. I learned this one from experience, this will usually kill the coral.
quarantine is the best method, and you can observe for red bugs, flatworms other unwanted hitchhikers. Iodine dips I don't find that usefull as it doesnt kill red bugs and it only "loosens" flatworms to make them more visible. It does nothing to their eggs.
