I tried Levamisole last march on them. I didn't get them again... However, I lost 85-90% of my acros in the process (kill the food source, kill the pest, right). I attribute the 'not getting them again' to TMPCC dips and QT. I also break them off of the spacer rock they are grown on to reduce the likelihood of getting eggs in. Weekly dips and inspections before going back into the main display. Pull them from the main display for around 4 weeks to make everything in the tank starve. Not the easiest thing to do when they attach and encrust to the rock structure, though. I think what hurt me in the Levamisole treatment was that I didn;t detach some of the larger piece from the live rock and dosed it all. The levamisole seemed to stick in the rocks and seemed to keep a constant level of medication coming out of the rocks. No definite proof of that, but when I treated Monti's for nudis, I was able to only put the corals in (no rock) and they all did fine. It took a lot longer for me to feel confortable with the nudi issue (6-8 weeks cause those gusy are hard to kill in the display and on coral). Good luck with it. QT QT QT in the future. When you have to break your tank down to kill a parasite because you were too eager to get it in the main display, you quickly learn your lesson... I did. This is not going to be a fun process. As a stop gap, he/she could just frag the crap out of everythign and dip the frags and hold in a different system until they die off in the display. That reduces the likelihood of eggs sticking around or making it into the QT.
