plz look at my STN

[willember]

Below is a picture of a coral I have that began to STN when my Alk got to 19 DKH and I was jacking around with flow and had some temperature instability. It took about 15 days to get to this point. That was more than a month ago. Since then it has not gotten worse and may be a tiny bit better. I got my Alk back in some semblance of order DKH 12 and Ammoinia - 0, Nitrite - 0, Nitrate < 5. Calcium still a little low at 350. It is probably 10 inches below and to the left of a 250W 10K Kelvin SE MH. The effected area is essentially the shaded region of the coral.

I am a little worried it may be acro FW since they are essentially invisable.

Any advise? Just keep trying to maintain proper conditions? or actively do something different?

TIA,
Willem

Is it possible to move it in a lower light area for a couple of days to give it a chance to recover?

There is a new dip out by TM (pro coral cure I think) that has been reported to remove AEF's, you could try dipping it in that and see if any come off, but I don't see any eggs, so I would tend to think it just got really stressed by the alk incident.

HTH,
