im having the same issue in my 30g. i have tried everything to stop it with no luck. i ended up tossing out 3 birdnest colonies last night.
ive decided to convert my 30g to just lps and softies and move all my remaining sps's to my 125g. thank god i was able to make 5 frags of my birdsnest.
ive tried carbon,gfo,biopellets,waterchanges, higher (10)and lower(8) alk(at 9 now).calcium and mag have always been good. 400-450 and 1300-1400.
ive tried amino acids,plankton feeding . nothing seemed to help.
my phos stays around .02 and nitrates around 2.
good luck trying to figure it out. i hope u can.

Not really. STN seems to be slowed or stopped but still no PE at all on the torts and no tissue regrowth of course. PE on the garfs isn't bad, especially at night.
Side note: The first sign something was amiss was the torts lost all green coloration and went all blue. Not a bad looking color but it seems to have been a harbinger of bad things to come. Or so it seems.

Take a look at this. Here is another example that makes me more suspicious that carbon is somehow involved. Dust maybe?

I am following this thread with much interest. I am running into the same issues with 3-4 of my corals that I have had for almost a year, one of which is an ORA Red Planet, which I have always found very hardy and forgiving. My tank is very stable. It seems like STN cropped up once I changed my Carbon and GFO. I also have been using WM EcoBAk for 8 months. My system is ULNS, but I feed heavy and have a decent fish bioload. I am thinking dust from either the GFO or carbon may be the culprit. After reading this thread I may up the flow a bit more. I have also thought that due to my central air being on, and my PH struggling to break 8, that may also be causing the STN. Has anyone reversed the STN of their corals without chopping them?

I cover the stn (which always starts at the base) with epoxy and have found this sometimes works. Pieces that stn are always prone to it in the future even if they recover and have started to encrust the epoxy. This has always led me to believe that a bacteria may also play a part.

Dixiedog, your aquascape on the tank is really nice. Curious how the suncoral is doing? I know they like a lot of food matter in the water. I shut down my GAC reactor tonight because noticed two of my corals looking a little suspect. I will provide an update this weekend to see if they improve or get worse.

If the reactor stays off for any length of time I would replace the carbon in it or rinse it well before using it again. Nasty stuff will grow in it if it sits there.

Of course, I plan on throwing it away and washing out the reactor. Depending on my results is what my next move will be. I just think the ROX carbon is just too aggressive of a carbon. One interesting thing I found in common between the two sps that show signs at the bottom is a gap between the base of the sps and rock. The rest of the base where it is touching the rock is doing fine and spreading all over.

I have seen this also, and have wondered what is going on in that space between the coral and the rock and why the stn always starts there.

Interesting. May be on to something here. If nothing changes by this weekend, I'm going to superglue that space and see how the sps react.

It could very well cause some people problems sometimes (although so many people run carbon, I would have to think the incidence of problems would be very low). In my case, I wasn't running carbon until after the STN started.
I was running Phosguard, but not carbon. When the problem began, I pulled the Phosguard and put in carbon.
I have. Never knew what the issue was though.
The sun coral is doing great! I don't feed it nearly as often as people say I should (sometimes just 2-3 times a week) and there's virtually no food matter in my water ever. (Makes me wonder if low nutrient could be an STN factor?) I'm picking up a pink-bodied sun coral this weekend to give it some company.
