I think there is a a bit more to it than will it kill them. What you're really after is killing them, and breaking the life cycle for any unhatched eggs. Trust me, if you have AEFW, there are eggs in the system somewhere. Weekly dipping in Bayer, for 6-7 weeks in a row should do that.
So I dipped the corals today that I thought looked like they had an issue 5 total all on same rack. I have other frags not on same rack but in same tank. Should they be dipped? They don’t show any signs?
Did you find AEFW on other acros? If so you need to dip everything (Acro). If you don’t something could slip through, and you’ll just have them back eating your corals in a few weeks.
