Jim @ Unrulymck has posted some interesting photos showing VSV eradicating red cyano bacteria in a matter of hours. Cyano and carbon dosing is a very sensitive situation because cyano can utilize carbon sources like vodka and sugar. When dosing any carbon source in the presence of cyano there is a very fine line of encouraging rapid growth or quickly eradicating. The photos below are just a few, the full image set can be found here.

Highly unscientific, but in my experience when a mature nutrient reducing bacteria population is established it can quickly out compete cyano, as Jim shows in his blog post. To be completely honest, I’ve never personally had a real cyano issue (knock on wood). Point being, cyano can be eliminated and controlled by other methods. Carbon dosing should not be used as a means to eliminate cyano. Nor should oxidizing agents or antibiotics, in my opinion.
Be sure to check out Jim’s blog and read the details on the photos. If we’re lucky he may even post higher resolution images so we can better see the effect.
