So I just lost several corals to RTN... I tried fragging few that started, and none of them survived. basically any corals that touched died. all the corals that were separated lived. Makes me believe it is something moving through the corals, but not the water or rock work. It's been several weeks now since this happened. Now for the weird. i had a healthy coral that had broke off and was living/growing on the sand. I decided to move it to the section where the previous coral had RTN'd (been dead for a while).. started to green/brown from algae... i glued the healthy coral to that area (on top of an old dead coral stump). 2 days later it starts to RTN and is now completely dead. all other corals are fine. there is definitely something there triggering this.
