Cyanobacteria: Nitrate or Phospate limited?

[acropora1981]

Does anyone know if the red cyanobacteria that many hobbyists deal with is more nitrate limited, or more phosphate limited?

[MCsaxmaster]

It is limited by the limiting nutrient...

Having said that, many cyanobacteria can fix nitrogen, so it may be easier for them to be phosohorus limited than nitrogen limited, but this is not categorically the case.

Best,

Chris

"also, cyano=> NO3 limited system.
They do well at low NO3 inorganic levels."
