Hi folks,

Hoping for some advice today!

I have started buying our first SPS frags from a reputable local shop. I purchased a small piece of what I believe is Digitata (Fluo green with grayish polyps). It is about an inch long and mounted to the typical disk.

I mounted the disk to a piece of LR near the top of the tank in the middle of the current from the return line. There is quite a bit of current going all the time (No Wavemaker). the first two weeks the polyps were out all the time, so much so that the frag looked like it was covered in fur. A few days ago the polyps started to not come out, and the entire piece looked a little gray. Yesterday my wife while cleaning, turkey basted the gray away, I am now left with a very white looking coral skeleton with maybe a little bit of green on the base.

I imagine the little guy is gone but I sure would like to know what is going on. All other corals and one Derasa clam seem to be doing quite well, although this is my first foray into SPS.

Parameters are as follows:

Tank: 60 gal Uniquarium (Sump built into back of tank)
Circ: Mag 9.5, and two small powerheads for extra aggitation
Lights: 2x250w 10k MH's and 2x96w Acitinic PC's
Skimmer: Prism Pro Deluxe (I know)
CA: 420
NA: 10ppm
Alk: 8.0
Spec: 1.025
Temp: 78

I will try to post a pic tomorrow and unfortunately I have not tested PH in a long time so I will try to do that as well. In general though I do not add any supplements to the system other than some phyto and coral vite a couple of times per week. I maintain all parameters through water changes and have not had any problems which is why I guess that I've neglected to check for PH!

Any thoughts would be greatly appreciated.

Best,

Rob
