I've been working with many wild Acropora colonies within the past two months and many die off rapid tissue necrosis. I've found an interesting "trick" to successfully saving colonies without fragging them. I've had a fairly good success rate by applying ample amounts of superglue over the infected area of the coral as well as an inch of healthy tissue from the necrosis. I would estimate that roughly 50% of the corals stopped RTN'ing and slowely started to grow over the superglue. If you try this method, be prepared to watch the coral for 48 hours and possibly frag it if it continues to RTN.

I've used the super glue trick for a few years, and, as Graham has said it works sometimes.
Wild colonies are good for RTN, its best to stay away from them and buy tank raised frags.

thanks for the tricks!!!! and yes these were wild colonies... ill try that if it happens again

 

[joerdie]

i take it no one really knows why this happens

I have very little experience with RTN (knock on wood)
Is posseble to think that the corals are just responding similar to the same stessor, instead of it being somthing that spreads?
kip, I take you didn't get a chain reaction from your event?

I've had wild colonies in my tanks for over a year, then, for no special reason they just RTN.
That's the main reason I'm staying away from wild stuff. Its really hard to do now days with all the new Aquacultured Bali stuff coming in..
OK, I'm bad:scared: I did split a Aquacultured coral with Roland a few weeks ago.. Actually Graham did one hell of a job splitting that coral in two.

Some guys on another board advocate that lowering your alkalinity reduces chances of RTN'ing and also that while starting RTN'ing it has stopped it. Don't know if they hold any validity in their statements, but thought I'd let you know.

 

[jauringer]

from my understanding tony detroit, thats how just about all the euro Reefkeepers feel. They like to keep there tanks at natural levels to keep RTN to a minimum. Not sure If that is truly the cause of RTN, but they have been in this a lot longer than us.

:yes: :yes: :yes:
i agree i do believe that is my problem as well.. i typically buy captive raised colonies, but every now and then i get a wild one... i have managed to save a couple of wilds that started rtnin and suddenly stoped... lost half the coral but....
