I have been fighting a battle with a wild colony of A. Subulata that I acquired roughly 2 months ago. The entire colony began to decline very rapidly a few days after being introduced into my system. Long story short, I fragged the snot out of the colony and after a ton of die off throughout the collection of fragments I got a few pieces that, although browned out majorly, were very promising.
These pieces have been mounted for roughly 2.5 weeks now and have begun to color up BEAUTIFULLY and there is a good amount of PE at night, limited during the day (can probably attribute this to my flame angel, he is on thin ice with me).
Well, I just noticed some STN on one of the frags. This same one had had a very slight bit of STN when it was mounted, but it recovered and began to encrust. My question is, can it make it back this time around with STN that has crept about 15% of the way up the stem of the coral? While I think I may have answered my own question, I just want some affirmation lol.
Now as to what may be causing the STN on a coral that has otherwise been on the road to being a very healthy piece. I am thinking that it could be a rapid decrease in nitrate and phosphate in my tank. Thursday I did a water change, cleaned the skimmer (and moved the cup down further as it was not pulling very much skimmate), and put some new GFO in my AC70. Life has also been very busy since Thursday and I have not been able to keep up with my daily frozen feedings on the tank. Could these factors cause a coral to STN?
And, one last thing, I also have a purple rimmed montipora danae from LA/DD. It was doing wonderfully until I mounted it on my rock and has since browned out. I cannot tell whether or not it is a goner. Does anyone have any experience with this subspecies of monti?
Thank you all for any input to this worrying SPS noob!
