Very Frustrating - Chalice Issues

[Darren]

Hello everyone. Tank is a 60G cube with AISOL Blues and a 20G sump. Tank has been up and running for over a year. Only 2 fish Foxface and Mel Wrasse.
Parameters below:

Alk = 9 DKH
Calcium = 395
Mag = 1290
Ph = 8
Sal = 1.025

No significant phospates or Nitrates detected. I am working on Mag and cal to get them up a little.

A couple of my chalices (I have about 20) and 1 of my acan lords (have about 3) do not look well. The acan has been withdrawn for 9 days now and the chalices are losing flesh from the top down. There is a thin amount of flesh on the top but the skeleton is starting to show. I have not moved them, made any changes to the tank, etc. All other corals sps, zoas, palys, frogspawn, torch, etc. look excellent. Some of my other chalices look OK but they are not as "meaty" as they normally look if that makes sense. I have run carbon, done multiple water changes and no difference. They are not getting worse but not better either. Any suggestions? I do have access to interceptor but was not sure if this called for me to introduce it to the entire tank. Any help is appreciated.

You might need to feed more. LPS need some nitrates(10-20ppm)

could it be salt creep that fell on it? when you dose, do you put the stuff directly into the tank or sump? any other meaty LPS affected?

Might be brown jelly or some bacteria infection if there is no chemical trauma.

Mine chalice did the same thing when i put it in my sps tank, which has undetectable levels of phosphate and nitrates

No salt creep and I dose in the sump. I feed all of my LPS 1-2x per week. Lights and pumps off and gently place a combo of mysis, brine, Rod's coral food, and cyclopeeze on the lps (chalices and acans) with a turkey baster. Interesting note is that the 2 chalices that are showing the issue are on opposite ends of the tank (all are in the sand bed) with chalices in between that show no issues...

Watch the foxface. I have one, and for reasons unknown, it decided to go after a brand new OME chalice when I added it to his tank. All my other LPS have been OK with the foxface.

 

[jcdeng]

then you might want to move them to give them a little more light and flow.

 

[Darren]

Yes I think I will move them to another spot to see if it makes a difference. I did frag off a piece of one of the chalices as it was growing across the sand and was an easy target. The frag seems to be doing ok.

Update. The receding of the chalices seems to have stopped. I did a few water changes, put a media bag with carbon in my filter sock, and dimmed my LED's a bit for the last several days. My other chalices are looking "meaty" again also. Not sure what it was but it seems to have "left the building".... Thanks everyone!
