I've never had to deal with STN or RTN as a reefer, I've only been keeping SPS a little over a year, maybe I've been lucky... but I need some help.
It all started when I removed a giant birds nest colony. I got it as a frag just to test my tanks ablity to support SPS and a year later it was the size of a football! I took it out to make space for some more exotic SPS. Well when I removed it the milka stylo right next to it started to RTN the next day. By days end half of the stlyo was skeleton. I trimmed the dead part off and left it at that. Over the next week or so it started to recover and I can see polyps growing back.
Then out of the blue my little colony of pocilopora RTN'd. Same story within a day it was all skeleton aside from two branches. It's been about a week but since that day no more has died, I'm hoping it will bounce back.
Now this morning same thing is happening to my monti cap. And this one I really love! The center scroll has gone white and started peeling away!
I just don't get it, each time I've had an event I've tested my water and it's fine, listing below just in case...
Alk - 8.3dkH
Cal - 440ppm
Mag - 1330ppm
PO4 - 0.09ppm
NO3 - 10ppm
pH - 8.0 - 8.2
Sal - 35ppt
Tank has been up 3.5 years.
The only thing different is it has been a little hotter. The tank is set 77-78 but it's been hitting 80-81 lately.
The crazy thing is I've got other SPS, millis, acros, some digi, all the 'sensitive' stuff has got polyps out loving life! No issues with any LPS at all. And the RTN'ing corals are at all different spots of the tank, so it's not localized to one area.
From what I can find RTN/STN seems to be a total mystery no one know what causes it or how to prevent it. And with this monti cap, dipping isn't an option.
I feel so helpless, just watching years of growth go up in smoke! I don't know if there's anything I can do, but I felt like I should at least ask the question.
