I think you are thinking about the rust colored flatworms and not the acro eating flatworms Deb.

Ah yes, I am !

It doesn't seem to work on nudis. It may kill some or at least irritate them enough to dislodge them, making them easier to see. I haven't been able to find anything that reliably works on nudis. The problem is the eggs, which none of the current dips/methods kill. They can be in any nook or cranny waiting to hatch. A few months back I received a really nice monti with nudi's, I resorted to fw dips and daily inspections, picking off what I could see. I thought I had them beat a couple of times but after 2 months I gave up. I read that Eric Bournman is releasing a new nudi treatment in "Advanced Reefkeeping" sometime in the fall.

Hi,

How did you manage to do a FW dip on a Montipora? I tried it before and the montiopora never survives its encounter with the freshwater. Any help would be great.

Thanks.

When I said resorted to fw dips that was after trying everything from Lugols, TMPCC, I even tried the Fluke tab treatment some are using for AEFW's. I figured Fw was worth a shot. The monti definitely took a big hit with fw, partially bleached out but not totally. It was still alive when I gave-up.
