Help Identify Unknown slime growing

[Ken Ken]

I have had this stuff growing only on my live rock for over 3 months now...at one point it got so bad I removed some of the live rock and scrubbed it away. Looked like it did the trick at first but started to come back after 2 weeks. Any idea what this stuff is? Only thing I'm doing is dosing 2 part calcium and alkalinity to maintain levels. Testing weekly to make sure levels are stable. Any help would be greatly appreciated

Looks like brown jelly/slime disease, it's a bacteria if memory serves. Manual removal (scrubbing) and a FW dip or some Lugol's usually does the trick.

What causes this ? are there any over the counter treatments?

I don't think an exact cause has been determined. I believe it's a bacteria that is present in most tanks but doesn't take hold unless conditions allow. Damaged corals are susceptible to it but I've also seen neglected tanks that don't get regular water changes develop brown jelly.

Dipping is recommended vs treating the entire tank, fresh water or Lugols after a good scrubbing.

The thing you want to do here is check the rocks and corals in question. If it's only on the rocks, it's more an annoyance, but if it's on the corals it can really be serious, and should be treated as as soon as possible.

That stuff looks pretty familiar to me!

I don't think water change is the issue as I'm doing water changes every 2 weeks....corals are all doing well...however I do notice it trying to grow on my green star polyps. It is getting very annoying. I want to beable to do something that will completly eliminate it. I have had several nano reef tanks over the years and have never experienced this stuff.

The tank is pretty stocked.....I lost a couple hard corals. Not sure if it was from the bacteria but they were new addition s that did not survive after 3 days of recieving.
