Trachyphylia dying, corals

[Zakaria_1999]

I have a 260 gallon tank reef aquarium which i added for new corals to.
NO3: 7.5
Amonia: <0.01
Salinity: 1026.5
KH: 9 dKH
PO4: 0.03
Temperature: 25 °C (77 °F)
Calcium: 410 ca/l
Reef tank age: 9 months


One of the corals which is identified as trachyphylia is not well i think. Its a white coral but one side it is turning black as well as there is a large black spot on it. I bought it 2 days ago the coral and it was all fine in the pet shop.

Here is some photos

Thanks in advance for helping

This coral looks bleached to me
Can you post a pic with more white and less blue?

You could try the kfc dip for a bit but its probably not bacterial and more of a different issue large meaty lps tend to love some spot feeding. Also could you get a picture of the hole on the trachy a lil better and what fish are in the tank.

What lighting was it under at the store and now in your tank. PAR if you have it. Is your SG the same as the store? I would move it down to sand at 100 PAR or less

I keep my trachy in the sand bed, medium flow, 100-130 par
