It’s crazy that you posted this. I just battled them for the last few months. It’s been terrible. I read a ton on it an ended up using the Safe-Guard with Fenbendazole. I had lost like 4 or 5 sps before trying this but it was honestly my last ditch effort to starting over with new rock. I didn’t lose anything, but it definitely affected a torch that I have. It’s been about a month now and I haven’t seen any. It will kill most of your snails, I still can’t put some snails in without them dying within a few hours to days. There’s a thread on here that explains how to do it, it’s a pain in the but sifting through the packets to get the fenbendazole, but it worked as of now
I narrowed it down to where mine began, there’s one on the bottom of this frag. They slowly took over and I had no idea what to do, killing them is hard. In total I lost 7 other SPS frags, and it sucked. And my wife was super ticked
I nuked all my rock before I put them in my 265 gallon because of the hydroids and bubble algae. I only put of few corals in the new tank. I dipped and scrubbed the one I put back and still got them. I could have got the from the cheato I put in a couple of months ago because I didn't see them before that.
