SPS browned out

[swnoob]

I have several frags that have browned out a few days after receiving from an online vendor.

STN from the base. i have 3 dozen other frags that are doing great. Some came with very little color and are coloring up just fine. The exact opposite of the browned out frags. All acclimated the same way.

Is there anything i can do to save it? Should i move to the sand bed or will that cause it to stress more? I did notice what i believe is called mesentrial filaments when lights out. No polyp extension.

Water parameters as follows per Red Sea test kit

Ca 400
Alk 8
Phosphates .08-.16
Nitrate 8
Mg 1560
Temp 77-79

ATI Powermodule 8x54w
10:00am-9:00pm
16" above the water line
frags are 12" below the water line

What are the white dots all over that frag?

It's the mesentrial filaments. They were much longer but retracted.

No red bugs or AEFW in the tank.

here is another picture showing what I think is the mesentrial filaments.

You can try dipping them in Bayer or any other dip you have available. There may be some kind of pest causing them to recede from the base; there may not. That would be a good starting point.

Any reason you are running your mag that high?

I chose not to dip because these corals came from the same vendor I used a few weeks prior. No issues with the first batch of frags.

Any reason you are running your mag that high?

I do not dose Mg. Not sure why it's so high. Maybe its the media in my calcium reactor? I do run the reactor wide open but with a slightly higher Ph so I don't melt as much media. Keeps the reactor from clogging and a very stable Alk at 8

what is your salinity? do you measure it?

what is your pH?

what is your pH?

Salinity is 1.026

Ph swings from 8.00-8.45

Are you using carbon?

Are you using carbon?

Running a couple of cups of premium carbon in a TLF150 reactor. Reactor output goes to the filter sock. I have always run the carbon.

Tank is a 120 gallon with a 40 gallon sump.
