HELP! Sick, Hairy 'shrooms
 

Need some assistance here please. About 3 days ago one of my hairy mushrooms was withered and had brown gunk around it. The mouth was white and extended. The next day it had shriveled to nothing and detached from the rock...DEAD. This malaise is spreading to all my other hairies of the same variety on the same rock. I've lost 4 so far. Up until this time they were very healthy animals. They've been in the tank for about 6 months.

No other animals seem effected, rics, zoas, sps.

Tank parameters are stable:

NO2, 0
NO3, 0
NH3+4, 0
PH, 8.2-8.4
PO, 0
Temp, 82-84

Did a water change last Monday (15%) and threw in carbon when I noticed them not doing well, Saturday.

Corals are fed 3 times a week. Nothing in the tank has changed recently.

Any help would be greatly appreciated.

Any lighting changes?

No. I'm thinking it's Brown Jelly Disease. Just trying to figure out how to treat with Iodine and Lugol's before it spreads to the other corals.

Trying to send you a PM, but your box is full..

Thanks..

Just noticed it and emptied. pm'd you.
