acro problem

[reefmut]

have had a tri color acro for about 2 months. it is a pretty large colony. Well noticed last pm that it is sloughing its "flesh". I had this happen to another large colony I had about 3 mo ago. I owned it about 6 mo. all of my other sps seems fine. I am running 2x 250 watt 1000k corallife and 2x110 uri actinics over a 55 gal + 30 gal refugium with calupera. this time i attempted to fgar the healthy lookig potion and am now dipping in lugols. any comments on what might be causing this or comments on if any of the frags might survive or are my efforts in vein?? all parmeters are actually right on exept salinity was 1.026, which I run it a lil high 24-25

Sounds like a bacterial infection. Lugol's may remove it from the host but it will remain in the main tank. You may experience this problem any time your parameters go out of whack. I'm not sure what you could dose on a stocked aquarium to rid it of that bacterium without effecting the animals you house within it.

Good Luck

All other smaller colonies appear fine this has only happened to the 2 large colonies...

Sounds like it could be RTN. Other than a lugols dip, there's not a whole bunch you can do to stop/prevent this from happening. Other chemicals may work also (like chloramphenicol) but good luck aquiring them.

Try a lugols dip, it may just do the trick.

How is the the flow through your tank? I have noticed that larger colonies (fresh from the ocean) require more current. My personally belief is that RTN is caused by deposits (coral excretion, fish excretion, etc.) settling on the coral itself which the allowed bacterial to grow and then attack the coral.

In lieu (or in addition) to a lugols dip, place it in the tank where it will get good random current.

I'd suggest fragging off any branches that are untouched and keeping them seperate from one another by at least a couple of inches. Keep in mind as well that if sloughed flesh hits another coral, it could readily spread if its an infection. If you see whole sections sloughing, I would pull it from the tank. Frag frag and frag again... if the infection dies off, you can readily glue all of the frags near one another and have a colony again in no time.

The hallmark of RTN is FAST. The whole colony will be gone in a few hours. If this not the case, it is not RTN. You just got tissue die off from what ever cause. Stress, injury, bacterial infection, bad condition, poor flow and others. If the die off progress, I just frag the colony. If it have stop, then just general care is what it need. In the meantime, check and correct any problem you have with the water. A water change can't hurt.
