As per Kent Tech D, "It is not recommended for colonial or other anemones, gorgonians, or polyps." "It is useful for small polyped stoney corals, lage polyped stonies, leather corals and most soft corals."
A very similiar recommendation is on Tropic Marin Coral Cure as well. Unfortunately I cannot seem to find the actual documentation. I believe the tropic marin has a small list of what not to dip. dont remember.
