I use FW for softies, but some do not recommend it. An alternative is to dip in old tank water with heavy iodine added. Just regular, over the counter iodine like you'd use for a cut, and drop it in the water, swish around, until the water turns darker color from the iodine. (it's almost impossible to use to much!). Dip in that mixture, and I'm told the flatworms melt right off. (Again, I use FW for flatworms, so I don't know about the iodine, but I use the iodine dip for my hard corals, like SPS and LPS, before putting in the tank, and the dip is harmless to them, but gets rid of pests.)
