So I tested water today and here are the results -- actually here is the last time I tested which was April 20th and today's. The tests for Ca and Alk are Elos, the rest are Salifert. My Refractometer is calibrated with RHF's recipe.
Salinity 1.025/1.025
Ca 450/450
Alk 7/9
PO4 0/0
Mg 1260/1230
Ph 8.2/8.2
So as you said Chuck, unless it is something that I cannot test for, I am not sure water params are the issue. The only other thing I can think of is if I am getting silicates -- if my DI cartridge needs changing. But nothing else is reacting.
The coral looks the same. I know you said several weeks but I was hoping for a bit more response by now. Although I still have a mushroom in the sump -- it is leaving on Monday. So if there are still some toxins in the water the coral may just stay static until they are completely gone.

| I would not expect a single corallimorph located in a sump to be an issue and only worry about such things if they are right next to and downstream of another coral. I have a few myself but keep them fairly isolated while running carbon at all times. Your parameters are spot on and can't see an issue there. If it were my system I would as Eric says, "have all guns blazing" with a skimmer in use and carbon (or new carbon) in use just as a precaution for a few weeks. Not being familiar with caribbean species or trying to avoid saying "a coral is a coral", I also wonder if this coming and going is a normal event for these types of corals. I only say that because I see some species here that also seem to have periods of recession and then regain themselves, and do so with such frequency that they build up quite the calcium carbonate base. Why that is, is still a mystery to me. Chuck

do you use carbon?

I don't have room at the moment to do anything but throw a bag of carbon in the sump. I was using the Seagel but thought it might be the cause so I stopped. I do have some other carbon that I bought so I can throw that in. I am in the middle of planning a basement sump and fuge and will put a carbon reactor in -- was thinking of using an old Fluval that I have.
Chuck -- I have had this coral for just short of two years. It goes through times where it will withdraw in sections for a couple of days and it does that at regular intervals -- like every two months. I was so excited with that first picture because I thought -- finally -- this guy is rocking! But that did not last long unfortunately. I will add carbon today.
My sump is weird too -- there is hair algae growing in there, which has never happened before, and there is a strong ocean smell. There are diatoms on the sand (I have a small fuge section) too so I am actually going to empty the sump and clean it out. I am not sure what has led to this as my parameters seem fine. It could be a flow issue in the sump as I use a filter sock because of serious microbubbles. But this is recent and I have been using a sock for the life of this tank.
So I will clean the sump including all pumps, skimmer, etc. And I will add carbon, get a new DI filter and keep my fingers crossed.

Good advice thus far, but do you have a magnifying lens or a scope? Look carefully at the interface between the skeleton and live tissue....really closely...and see if you see any tiny tiny flat black specks or tiny brown cylinders moving in and out of the skeleton.

Hi Eric --
I can't see anything. I got the last hairy mushroom out yesterday, cleaned the sump/fuge up, put in carbon and it is looking a little better. I have to get on an airplane but this weekend I will post some pictures and I will try and get a close up picture too. I am cautiously optimistic.
