Interesting article from recent issue of Coral Magazine on feeding of cyano, that might help to understand better the persistence of cyano even in nutrition deprived environment.

In a continuing battle with cyano, I'm going to run larger quantity of GFO and see if that makes any measurable or visible difference. I'll also experiment with increasing the change frequency. From what I've read online, GFO has the capacity to absorb a lot of phosphate very quickly...but that might apply only to those with high phosphate levels to begin with.
My phosphate levels are always quite low, so it is likely the GFO lasts longer.
