brown jelly infection

Question
What do you recommend for dealing with brown jelly infection.  It's on my bubble coral now.  It was on a torch coral and killed about 80% of that one.

We had to split the torch and have now split the bubble.  We dipped the bubble in Reef Dip 3x but the jelly keeps coming back in one spot.

This also seems to happen  at only 1 endof the tank.  I thought with all the water movement the cause of the infection would be equally dispersed.


Here's the setup

150 gallon tank with 300 gallon wet/dry sump+ skimmer
150+ punds live rock, live sand bottom

Residents

1 yellow tang
1 lavendar tang
2 clowns
2 yellow-tailed damsels
6 green chromis
1 purple firefish

2 peppermint shrimp
1 hermit crab

1 torch coral - single branch now
1 bubble coral - newest resident, 10 days in tank
10 mushrooms
1 Xenia with 9 stalks - pulsing strong
14 total yellow polyps
2 groups of zoanthus
1 open brain


Water quality

Ammonia - 0
Nitrites - 0
Nitrate - 20
Phosphorus - .02
Calcium - 450-500
SG - 1.025
Temp - steady 78 degrees

Lights

2 VHO - 6:30 a.m. to 7:00 p.m.
2x175 metal halides - 1:00 p.m. to 6:00 p.m.
1x3/4 watt moonlight - 7:00 p.m. to 6:30 a.m.

Thanks for any help you can offer.

Answer

Tom,

The course of action that you have chosen I would have done 100%.  I am not sure why it keeps comimg back. I would place them in a separate enclosure and treat them as you are. I have only dealt with this type of infection once.  It took 2 weeks of treatment to eradicate this infection. Also check the temp,  I have read some articles regarding temp and inverts immunity system.  The article talked about lower temps can suppress the animals ability to fight off certain diseases.

Good Luck Todd
