Help with Nudibranches?

I just came back from a two week vacation, and while I was expecting the worst, I was still a bit disappointed to see all my Zoanthids and Palys closed up tight. After a massive water change, they remained closed for a day or two, and then I realized my problem. I saw a few little nudibranches climbing around. I hate these a-holes, and while I've noticed them from time to time, I've never seen more than one until now.

I have a 5.5 gallon setup, and the layout of the rock-work really makes pulling pieces out to dip prohibitive. So my question is whether any of you has used any full tank treatment to deal with flatworms or nudibranches. I saw Salifert Flatworm Exit mentioned on a couple of websites. Anyone have any experience with this stuff? Does it work if you're not using it to dip individual corals, but treating the whole tank?

Thanks for your suggestions!
 
Think you are I. Trouble. Trying to get the nudie and eggs are going to be. Major challenge, even if you take them out for a dip. Good luck... I lost all my zoas to them once. Left the tank zoa free for months to starve the remaining ones out.
 
You have to pull the rocks for best treatment. Get a 5g bucket and some coral rx. Place a powerhead in the bucket and start dipping. Leave them in their for a bit and blast the rock with the powerhead. That's the only way I was able to get rid of them. A full tank treat might wipe out the beneficial fauna in the other rocks and sandbed.
 
I also want to add I left them in the coral rx water for about 20 minutes with no negative effects. Also try using a jet style powerhead like a maxi jet. Not a koralia type. Plus you only have a 5.5 g tank. Honestly, how hard could it be to pull rocks out.
 
Ditto on dublo8 said. But I would also add with zoas I have found doing a RO/DI bath will kill them and flatworms. Come on man to hard to take the rocks out of a 5.5. I get it you got the perfect rock stack have you thought about getting some superglue and gluing them together in this position then removing them all together for a dip.
 
The problem with pulling rocks for dipping is that I have corals growing across, in between and interconnecting between the rocks. I suppose I could just hack and slash and hope it works like a bastardized fragging, but a full tank treatment seemed like the obvious answer. FWE claims to be reef safe for full tank dosing. Any thoughts?
 
I used Salifert's Flatworm exit in a QT when I had an infestation. It worked. I treated the QT until there was no sign of them.
 
Yo if your remove the sand bed and the filtration you could do a full dose in the tank then do 100% W/C after the recomindid dosage time. Go BB for a little while then add new sand and replace the filter media as normal.
 
Since my pico is at the office, I was able to stare at the tank quite a bit and managed to manually fish out about a dozen nudis. I went out and bought Salifert's Flatworm Exit, but when I came into the office this morning, all of my Zs and Ps were open and looking happy.

I still dosed the tank this morning according to the directions, but didn't see any dead bodies all day. I don't know if it didn't do anything, or if I already got the offending a-holes. I'll keep an eye open, and probably will dose again in a few days just in case some eggs hatch, but looks like I may have avoided disaster.
