STN and being unable to identify the cause!
Bryopsis sucks too!
You know, I've had a bit of this lately...I somehow thing it's related to the sudden reduction of zooxanthellae, leaving a coral basically starving...and slowly deteriorating. I found the ones I lost were ones that had the most brown to begin with, the ones that had more colour have done just fine. I'm still trying to figure out what the hell I did.... I wonder if it was a large water change with cool water (wasn't using a heater on the water tub), or if it was some contaminant...or if it was lighting. You recently upgraded your lights, no?

Yes, I upgraded my lights several months ago now. I just noticed the stn on a couple mini colonies. My millies arent having the PE they usually do either. My colours are decent, my params and salinity are good, regular water changes, low nitrate and phosphate...???

???
Going to add some amino acids for a few weeks and see if there is any noticable difference,

Keep me updated, I never had stn before, but I changed a number of things at the same time (stupid stupid stupid) so it's hard to pin down what I did wrong like I normally can. I get all "this setup is bulletproof" but it's not. To be honest I haven't lost anything I like, and it was good to clear out a few that were just brown masses. LPS seemed to take off with the new lighting upgrade, as did coralline, so I really think the UV was lacking in my old setup. Frags I got recently are fine, ones I had forever were the ones that bleached, so I'm really thinking they were just totally acclimated to the old lights. What AA are you going with?
