Simple solution, add more nitrate! AND possibly more organic carbon. obviously if your nitrate limited you need to add nitrate to remove your leftover phosphate levels, but, if the level of phosphate is too high, then just like to remove phosphate you have to add more nitrate because you are nitrate limited, you may have to add more organic carbon simultaneously as by increasing the ratio of nitrate to phosphate, you may have also decreased the ratio of organic carbon to nitrate, and therefore may have (to a certain extent) become organic carbon limited again.

I've been nitrate dosing for a few weeks now, no gfo, 0.3mg/l nitrate, daily.
Cyano started all over within 3-4 days, it lasted just over a week and receded rather quickly.
No3 now reading less than 0.02, Po4 0.01. Still feeding 3x daily heavy.
