Niether. These things are the lil brutes on the block that all the lore claims they are.
Lastnight I saw no result at 1.5 at 240/1/2t concentration.
So I added another 1.5 per g
Nothing 1 hour later.
This morning nothing.
So I added another 3ml per gallon at 240/1/2t conc.
Still NOTHING 1 hour later.
Said to heck with and poured balance of total of 240ml of 1/2 t mix
STILL NOTHING.
But worms of all types except feather dusters appearing and going into death throws.
VERY IMPORTANT DETAIL---->So now I'm at point of no return on feasability of total tank dosage. No matter what this is a Quarantine or temporary dosing bucket task.
----> The next thing is to come up with a kill concentration that will save the coral in an isolated dosing method.
So Next,
I mixed up 240ML to 1 TEASPOON of LEVASOLE.
I poured the entire 240ML into the 20.
NO APPARENT KILL.
BUT, It has made them more mobile.
So I am thinking...ok...they are upset.
Lets see if we can just burn them.
They hover along the good edges the most. So I brought my windex of the reeftank...Kalk soup/paste like I use to control Aptasias, burn back battling corals, vermitids, micro algaes etc.
I 1st hit little green patch like that which is described in a nudibranch ID thread as being an egg patch. I then hit the largest adults. I then hit one of the patches of juvenilles hanging out in their little patch.
Boom big reaction. Adult cook. I syphon them off with eye dropper without any difficulty. Empty dropper and rinse in hotwater. Then the green patch with may or may not be the eggs comes up completely. Again rinse eye dropper and repeat.
Little juvi's most come up without a fight. Rinse and repeat.
I think that the way to go with these guys. Is if you have them in your tank, you need to yank them out and quarantine or throw away the coral. AND that tank will have to be Monti free well past the 6 months that others allege is their dormant cycle maximum. My testing will end with this in 30 days. If corals do not reinfect then great. But I am still yanking the liverock out and tossing it into a bleach vat before it gets used in any of my tanks.
The amount of LEVASOLE required to harm them would no doubt stress and kill off every other crawler/worm/fauna in the tank.
I think it may or may not be a useful "irritant". I am going to leave the dosage as it sits right now. Then I am going to not kill off anymore them and see what happens. Manual removal and scrubbing just seems like a big pain. I am under the impression that irritating them...or putting them into stress helps and that no matter what the kalk enables them to be nuked and removed. And in just 5 minutes of the Kalk soup on them at that. The other reason I am leaving the setup alone and will discontinue kalk nuking. Is I want to see if there is a a rebound in population and of course if they infect the 2 new, fresh frags.
A side note...another one...sorry. Oomed the banned Tetra Product contains Quinine is rumored to be useful to battle these nudis. Quinine, which under certain avenues can be obtained. But it comes in 5 forms. Getting to the nitty gritty on which one is in Oomed, might be another method. But that's another test. This was a side bar test from the flatworm total tank dosing trial since the nudis were posted as available. However, it looks like no intank treatment should or could be safely done via LEVASOLE.
I will be thinking about another direction over my time in Chicago. If a brainstorm hits I will clear the tank of LEVASOLE and try something else. Unless someone has some Quinine or some Oomed I am thinking that a clear tank of LEVASOLE and a simple Kalk Nuke and syphon approach may actually prove to be a very good method. This as in aptasia removal would be a long but fruitful measure as far as an in tank removal method...eventually. But ultimately I think that putting a tank into a 1 year Montipora quarantine once they are discovered in a main system will prove to be the best method. I wish I had a better turnkey answer, but that looks like the long and the short of it.
