Nov 2021 - couldn’t find my filter after the move. Regardless the colors and PE were looking amazing. Extremely happy with growth and color

Dec 15 2021 - I noticed colors weren’t as vibrant, PE was minimal.

Dec 30 2021 The frag has been STNing for a couple weeks now. I cut into three pieces around the 16th to try a couple different measures. All pieces showed some STN initially and have been holding with no further tissue loss in last three days since 12/31

I have about 50 sps frags ranging in difficultly. Some of the acros that I have had the longest showed basal recession in late November. I chalked up to being related to moving process they went through in October. Those basal recessions ceased by the end of Nov.

Phosphates were recorded at 0 on 12/18 and bottomed out subsequently again on 12/28

I am linking these recessions to 0 Po4 anecdotally. I have not been able to determine other possible causes at this time. Recession “seemed” to halt once phosphates were restored to non 0. They fluctuate daily between 4-20ppb phosphorus. The largest decline happens between 7am and 7pm where the typical decline is 8ppb. Overnight is about 5ppb consumption. Below chart is PO4 converted from the phosphorus ppb reading.

I got a gallon of my tank water for you if you want to bring your phosphates up! I'll even fill up during a feeding for the extra phosphate rich water.

PO4 fluctuations within 24 hours roughly +/- .03-.04.

Coral skeleton is starting to cover in brown slime. No further tissue loss since last update.

Did you add GFO? Many of my corals bleached (also lost a WD frag) due to GFO (with only half dosage) so I now dose bacteria, carbon, po4, and no3 manually instead,

No GFO. When I do use it, I use tablespoons at a time and slowly increase over a week.

No other acro tenius are having issues currently. The Walt Disney infront is displaying great PE, so I am hoping that the necrosis episode is over and the frag starts to recover (i highly doubt it will).

Very interesting situation.
 
This particular coral has been STN’ing about 65 days now. It’s over 2 years old and was one of the tester SPS I put into the reefer 250 along with a stylo back in 2019.

The STN doesn’t look like anything I’m familiar with. You can see in the second picture where it appears the outer layer of the skin has peeled away exposing a lower layer. I’m not saying there are multiple layers, just explaining what it looks like to me.

I took the frag and shaken it up in water to see if any flatworms fall off, but no avail.

I’ve also never seen STN take this long with only a golf ball size frag.

There are two other frags that are almost completely dead. They are at about 30 days now and they are 1/4 the size of this one.

The 50ish other frags are not showing any signs of irritant. I can’t find any pests like flatworms or red bugs and the STN is progressing so slowly.

If anyone has any ideas or sees anything in particular worth looking at I’d love to hear it as I doubt once these three frags are done that they will be the last.

Here is the dip after two frags. Curious if anyone sees anything cause all I noticed was copepods and specs of detritus.
