Sadly, as the result of some crazy alkalinity swings over a 5 day period when I improperly calibrated my dosing pumps, I had an outbreak of brown jelly disease ("BJD") that ended up killing four out of seven of my Euphyllia (2 torches, a frogspawn and a hammer). The BJD started on a torch and spread to the other torch - this happened about 4-5 days after I got the alkalinity stabilized. I tried my best to get the torches out once I knew it was BJD but I was probably too slow... and about 7 days after I removed the torches, my hammer coral, on the other side of the tank from the torches, succumbed to BJD as well. Finally, about 3 weeks later, one of my frogspawn that was in the vicinity of the hammer but touching, came down with BJD. It has now been 32 days since the last case of BJD on the frogspawn and my remaining Euphyllia are all doing well...

My questions are:
  1. Am I going to always be at risk for BJD to attack my Euphyllia even if my parameters are all stable and within the acceptable ranges?
  2. Hypothetically let us say that all of my Euphyllia end up perishing as a result of BJD - would I need to wait to add Euphyllia again? If so, how long?
  3. Do I need to be concerned with BJD spreading to other corals? I have zoas, acans, favia, monti's, etc.
Finally, for reference, my water parameters are as follows (and have been stable since the alkalinity swing disaster):

Salinity: 1.025
Temp. 78.5 to 78.8 Fahrenheit
Alk: 8.1
Calcium: 410
Mag: 1350
Nitrate: 3-5
Phos: 0.12

Thanks in advance for any help and please let me know if you need any more information about my tank.

Does anyone have some thoughts? Thanks!

I've lost 2 torches, 1 month apart with a dozen other euphyllia in the tank. In each case, there was stress, either from mechanical damage and/or my moving the coral. I think the root cause (bacteria?) Is always present, waiting for a weak, stressed coral to infect.

This can be very frustrating I've had the same tricolor frogspawn since the mid 90s and I will periodicly have brown jelly pop up. WHile it's usally associated with sudden temperature changes or alklinity swings like the OP it has shown up when there hasn't been any apparent stress event. This thread on Euphyllia and BJD might be of interest.

I’d recommend a cipro treatment and or a chemi clean dose to the tank. There seems to be some good success coming from those options. There is a good thread on here about it.

Some get lucky, and it just stops. Some dont.
I did every dip, treatment with furan, iodine, witch hazel, and still lost the majority of my collection back in october. One survived. Thats it. Just one. Of about 20 in a 50 gallon euphyllia tank.

I did find that after i installed a uv, it seemed to stop spreading, and it eventually stopped after consuming the last few hammers it got to.

There are dip write ups, they seem to help, but i have yet to see a difinitive solution.

Might also add. This one, was different than the bjd i saw first hand in the early 2ks. This one appeared more like polyp bailout from the outside. But decimated the insides all the same.

I had it nearly kill off a candy cane coral colony. What I did was frag off the little
bit of tissue that looked healthy still and gave it a good dip in iodine and threw out the rest of the coral which smelled Like death. It has recovered quite well over the last year or so and I haven’t seen it come back.

You pose the right questions and I don't have definitive answers. I have a belief that BJD is always around, kinda like dinos are always around. They just need the right conditions and a favorable host. While I cannot (today) see any BJD or dinos in my system, if I take a large scraping under a microscope I can find both. Dinos at 400X and BJD at 1000X.

So my advice would be to hold off on adding new (and therefor stressed, Euphyllia) until the population of BJD seems controlled.

And yes, BJD can feed on many other organisms if needed. Even coralline IME.

Thanks for all of the input, it has been very helpful! It makes sense that BJD is always around so my goal is to prevent the right conditions for a BJD attack from occurring.

My remaining Euphyllia are still doing well and my parameters have been stable so hopefully the BJD population is getting under control.

Can you give me a good description of brown jelly disease? I had some sort of brown looking slime that seemed to cover the rocks in sheets and seemed to smother the corals and the mushrooms. I suctioned it off as much as possible and started running a protein skimmer. I even took some of the rocks out and scrubbed the stuff off. I have not seen it return since I have been running the skimmer. I don't know what it was.

Definitively, at 1000X this is what it looks like below. Naked eye it looks like brown slime or jelly that consumes recently deceased LPS flesh most often. But I have seen it eating dead coralline algae on the rock also on some occasions.

It is my OPINION and experience that it is more often an after-effect than a cause. It is my experience that a given LPS head once infected is a goner and should be removed ASAP. Then try to figure out what is stressing the system. But there are different opinions on this.

Do you think there are benefits to turning your skimmer off for periods of time?
