Unidentified coral pest

[Thanzor]

Can someone help me with this pest? I have been blowing it off the coral twice a day, but it very quickly comes back. It has only been really affecting this coral. How can I solve this so my Coral doesn't die? Thanks everyone.

The picture is not clear, try getting a better one (under white light).
What coral is this?

I think it's a Duncan. I will get a better picture tonight. It is covered in a white or grayish slime that can be blown away.

Please do. Also, what are your parameters lilke? Any drastic changes in the tank recently? How long have you had this coral?

 

[Thanzor]

Parameters have been constant, only issue is nitrate is probably too high around 20ppm. Have had it for about a month.

Sounds and looks like bacterial infection which prob means the Duncan is toast.

dang. Should I remove it from the tank to prevent spread to other corals?

 

[JGT]

Yes, it appears to have brown jelly disease which can spread to others. Turn off all power heads and slowly remove from the tank so you don’t disturb the jelly.

Bacterial infection either way is my opinion. Pic looks like bjd.
