RTN "Argh" Anyone with a fix?

[TazzBear]

I purchased a LARGE A.Loripies and had it in my sump for a couple days to acclimate to the water conditions and lighting increase. The LFS had NO on it, I had it in VHO for a week, and I now have it moved into the main tank, but only because I noticed RTN on the lower portion and I know I needed additional water flow to help aspirate the living corals better. So, the old iodine dip or should I just frag and super glue the cuts sealed to stop this? I hate losing coral to RTN, but what you gonna do. I am calm about this because it happens eventually to everyone. Just am curious if anyone has had any REPEATED success with any therapy. And not therapy for me, but to get rid of this issue. And don't start asking if I have done anything and what my water conditions are like. I have over 30 SPS and not the frag starters you get from online sales. And they all grow nicely. I just want some opinions on any therapy that anyone on here has had repeated success with. I don't want to sound rude, but I don't want to get into water quality, lighting and so on. Just a therapy that has been tried and has turned out to be a success in stopping this darn RTN. I will be fragging some of it today since this head is about the size of a cantaloupe and can provide about 50 frags or more. I just hate to lose it all.

It is a wild head they do this alot

fragging is the only way to save the colony

I've heard about a new product by Seachem whic you dip the coral to stop the infection. I have tried it yet!!

Anyone else heard about this product?

I fragged the puppy already. I decided to cut 1/4 to 1/2 about the visible RTN line, did a .005 Lugols wash, and glued all cut areas and they are now attached to some ruble. Man, I hated doing it. But you are correct, collected heads do this from time to time. I was told this was a small head from a reefers tank. Oh well, I guess my understanding and theirs is different. I did change the water on the bowls each time I handled them. So, hopefully the pathogen or bacteria will have been killed and will spare my frags. Got some big frags. Also, I think this may be an A.Kirstyae. I got a REAL close look at it today. Grin

Yup, frag well in advance of "RTN" areas. Wild collected A.loripes seems prone to these problems

I know how you feel. I lost about 2/3 of my SPS to RTN with a day 1/2. They had been doing well for about 6 months and showing growth and nice color but now all gone. I don't know if I will try them again.

Got about 40 frags from 1/4 to 3.5 inches. About 10 of the frags succumbed to the RTN by the end of today Friday. Just for fun I decided to add Ozone into a powerhead. Man, the RTN infected skin sloughed off the corals real fast. Not sure if it did any good, but the other 30 don't show any signs of RTN YET. I did Ozone for about 3-5 minutes. Since ozone has an ionic bond, they will bond with anything and bleach it dead. I was hoping that the ozone would flush the slime from the corals just like iodine does. I am prepared to lose the whole batch to RTN so hopefully this experiment will help in the future. I did 10 on ozone, 10 untouched, and 10 with another iodine dip. They are all isolated in a 30 gallon frag / quarantine tank. I have not heard about this product Humilis. Do you have a name for it? I'm usually not one to JUMP at new stuff but when this happens, you never know. Someone has to be the guinea pig.
