Who Gives A Fish Forums

Got flatworms on my hammer coral and I'm trying to figure out how to get rid of them, been there for a few months now. Only seem to be on the hammer, none on my other corals, which is weird. Doesn't appear to be hurting it or anything, but still would like to get rid of them. My hammer is attached ...

Any better suggestions?
