Acro bleached

[Cfabia1]

I have had this frag for a little over a month and it is the first acro I have tried in the tank, all other sps are fine. It always had great polyp extension and some growth.
CA:410
Alk:9
Mg:1320
Po4: 0.08
No3: 5
Ppt..34
All red sea test kits and ati refractometer. one second it looked perfectly happy and the next like this.

This looks like tissue necrosis to me unfortunately did this happen quickly, or has it slowly turned white?

Acro bleached

That coral is toast. I bet if you hit it with a turkey baster the rest for the flesh would fly off.

Those parameters look ok, but the real question is stability. How stable are those parameters? Any recent temp spikes?

 

[Cfabia1]

All the params are stable, but I haven't been checking temp as often, I guess it's time for a chiller

Fast within an hour

 

[plyle02]

RTN sorry you lost the frag, how are other special behaving?

 

[Cfabia1]

Everything else looks happy. I think I'll wait on acros until I get a chiller, and my nitrates down closer to 0

 

[swk]

Your nitrates are not a problem. Dropping them to zero will make things worse.

 

[Cfabia1]

Good to know. Thank you

this happens to even stable tanks, I've had it happen a few times. a lot of times they only partially RTN they end up coming back. however I have had a couple rtn completely overnight. it has always happened to me the day I get the frags though. so it's weird you have had it for a month and it's now happening.

Don't get your nitrates to zero, you need them in your tank. What's your lighting, and how did you acclimate it?

 

[Cfabia1]

I have three radions at 70% 10 inches off the water. I did just change from 20 k to 10 k a week ago. Drip acclimated for 30 minutes then a dip in coral rx.

IMHO it mightbthe the radions. Some sps just dont like that light and some do.
What light was it under before you got it?
Dip the coral before you throw it away to check for pests.
Sometimes it does take a while before the sps will not deal with a certain type of light before they just up and rtn.
I bet it was under mh or t5 before it came to you.

Try dropping the white value have to remember leds are more highly focused light source than halide or t5 so light has a tendency to be stronger in the focused area

He said the restbof his acros are fine so I wouldnt touch anything. Moving the coral around mabe is something he could try but if its gone its gone and if there are pests on I wouldnt bother putting it back in unless its a crazy expensive frag of corse but even then I may not risk my system for one frag.

I am sure you are right about it being under metal halide before, the frag was from live aquaria and I believe they use 20 k metal halide. I will try a longer light acclimation on the next frag I get. Thanks for all the replies

[Cfabia1]

Frag has been removed from the system

 

[nycreef]

Good safe move. I would have dipped it before throwing it out just for curiosity. If nothing came off then your good and sleep better. If you saw anything bad then the nightmare starts.

 

[Cfabia1]

Thats a good tip. Never thought of doing that
