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.

I've read up on the FWS and my understanding is that it minimizes the chance of these worms going after the sps as the sps builds a slime coating that the worms do not like but it does not kill them. Can you direct me to the link that tells me FWS does get rid of them? I am planning to get it anyways.
Thanks

FWS doesn't kill them, just "strengthens" the coral. Also, as far as lowering temps, this reduces the metabolic rate of corals and inhibits growth, meaning that if/when a coral is damaged, it's ability to heal itself is compromised. Not an option I would choose.
I'm hoping that on the small frag they came in on, that there was only 2 or 3 on that piece, and they were still there when I removed it. I counted 3. If there were 4, then I might have an issue, I might not. If one let loose into the water column, it's possible a fish would have eaten it. Fingers crossed.
