There are lots of posts associating GFO with RTN/STN episodes. Most commonly, a sudden alk shift is suggested as the cause.
Here is a recent study that associates nutrient imbalance with coral bleaching - in this case sufficient nitrogen and insufficient phosphate.
Dr Jörg Wiedenmann, Senior Lecturer of Biological Oceanography at the University of Southampton and Head of the Coral Reef Laboratory, who led the study, says: "Our findings suggest that the most severe impact on coral health might actually not arise from the over-enrichment with one group of nutrients, for example, nitrogen, but from the resulting relative depletion of other types such as phosphate that is caused by the increased demand of the growing zooxanthellae populations."

This kind of runs contrary to current practice, where we strive to eliminate phosphate but tend to ignore nitrate as long as its below 5ppm or so.
What do you all think?
