Why? Out of the blue...

[myakkareef]

I had a rock that had about 30 mushrooms on it, it had been in the tank for over 2 years. This reef has been up for over 10 years now and has been what I call very stable for the last 7 years. No livestock of any kind has been added in the last year atleast.
Out of the blue this one large mushroom rock developed from everything I have seen "Brown Jelly" disease. Atleast 20 or more mushrooms just went to snot..I pulled the rock out and flushed real well. Did a WC and started a large amount of carbon in a reactor. The rock had about 10 remaining mushrooms on it, and it looked clean and the remaining shrooms looked healthy. I put it back in the tank and overnight those remaining went to snot as well.
At this point no other inhabitants where inflicted. Now on day 3 most of my leahters pulled up tight and are sloughing tissue.
These are all 10 year old plus leathers, I pulled them all out and did a lugols dip. Some of them look alttle better, except for a large yellow figi. But it is still solid and not disentigrating at this point.
All other inhabitants seem fine clams, anenomes, fish, lps, neptheas, anthelia, zoas, colts...
So does anyone have any clue what might have caused this initial mushroom rock to turn so quickly.
As far as water parameters, this is what I have.
Alk 2.5, ph 8.3, sg 1.025, temp 78-80 (heater and chiller), drip kalk 24/7 and have for many years.
I really can not give any other data since these are the only things I have tested for in years as well.
Sorry for the long post, just looking for an answer. 12 years and I have never seen any thing like this mushroom rock going to Brown Jelly...Almost in a blink of an eye...

Sorry to hear whats going on, I just had a similar thing happen, I had a beautiful pocillopora for a year and a half it grew, survived a dinoflagellate outbreak which destroyed most of my hard corals. Saturday it looked great, Sunday afternoon like this.

I removed it from the tank removed as much of the infected coral as possible, treated with Seachem reef dip, and put it back. By the time I got home from work Monday it was completely gone. No changes to the tank aside from starting GAC use a couple days prior. Parameters had just been checked and were fine. Fortuanately I have some previous frags of it growing so it wasnt a total loss.

I posted with Eric Borneman on Sunday looking for help, and followed his advice, but still it wasnt salvageable. He told me that the reasons for the sudden appearance of brown jelly arent fully understood.

I only have 1 small sps, and it is a pocillopora I believe but the one that grows flatter potatoe chip like. It was not efected at all. The actually only thing that the Jelly just wiped out in a matter of hours is the mushroom rock. I believe the leathers just took friendly fire.....
The leathers do look better this morning after the Lugols dip. But untill the lights come on and I get home this evening I won't know for sure..

We import pathogens on a regular basis when we feed the tank. It's likely a vibrio bacteria. Do you feed the tank clams, mussels or scallops? They're almost guaranteed to carry it.

The mushrooms may have released their toxins and affected the leathers, or it could be the same reaction to the vibrio.

I have not for quite awhile, but I did make a batch of home made food and had fed it for quite awhile untill about 6 months ago and it ran out. Since then it has been pellets, dried cyclopeez, and mysis...
This came on so fast, I wish I had daily photos to see when it really started. I do look at my tank daily, but must not have picked up on this, till it was to late...

It does happen very fast, my pocillopora which is larger than a fist was completely gone in less than 48 hours.

Graveyard, I'd bet money that the frogspawn right there killed that birdsnest.
