I had some success fighting them. Last year I dosed zeovit flatwormstop for 3 month at double or triple dose and it wipped them out for a while. In december, they came back on my hyacinthus and millepora (they seem the most susceptible of having them) and after on some other acros.

I went back to flatwormstop again at low dosage and I'm trying other tricks in fighting them. Apparently flatwormstop contains some phosphorus (a chemist did some analysis on it) and some reefers noted that a sudden drop in phosphates could trigger an infestation. So I guess it's a good thing to let some phosphates in your system (I'm at 0.03). Secondly, Claude Schumacher from Fauna Marin advised me to lower the temperature to 73-74 to limit their growth. I'm at 75-76 right now and with a frequent basting of corals, they do get rarer and now I just have 2 infected colonies and they do get better.

I don't like dipping solutions as it seems harsh on the coral and a PITA to do.
