Help my Coral!!!

Rory's Reef · Oct 21, 2016

So this is a brand new Acro I got Wednesday. It's one of seven new corals and the only one showing these weird blotches on it. Can anyone tell me what this is and how (if possible) I can fix it. I have no idea what could be causing this.

Thanks for any help!

Looks like RTN, did you dip it in anything?
Also, Tell is about your setup and parameters...

Rory's Reef · Oct 21, 2016

PH is currently 8.2
NH3 and NO3 0
Mg - 1400
Alk - 9.2
Ca - 400

They're currently sitting in my sand bed acclimating to my leds. It appears to have happened in the last 24 hours.

And I used coralRX dip on all of the corals before adding them to the tank.

What other information would help?

You may want to reduce your Alk to @7-8. Does look like the frags are in bad shape. When mine have looked like that, they haven't made it. Flesh just kept on peeling off. You may try putting in less flow. Sorry.. can't give you better info.

So unfortunately I had to go to class and after 5 hours of being gone this is what I came home to. I'm pretty sure there's no chance of saving the poor guy, but I did read somewhere that using superglue on the decaying parts can sometimes help, but usually only in the case of STN. I'm giving it a shot none the less, but I expect he'll be dead by tomorrow morning at this rate.

At this point I'm just curious if I should be concerned for any of my other corals? So far this is the only one showing any signs of RTN or STN and the 5 acros that were already inhabiting my tank before the addition of these 7 new SPS are still doing great.

I do want to get my Alk down to around 8. Do you have any suggestions about what the best way of going about his would be @Salty1962 or anyone else?

Cut away the very tip, you might have a chance to save part of it...
Do it quickly

Also,
Just an FYI.... try to make sure the frag has covered most of the top of the plug by encrusting, better chance of surviving IMHO..
I try to stay away from fresh cut frags, unless they are free..

Thanks, I tried to get to it in time, but it was already creeping up the back side of the tips anyways. I don't know if this is something that WWC covers in their 10 day guarantee, but I'll be sure to ask them.

. I'd not heard that before. I'll keep an eye on that in the future.
