Cyano feeds of the substrate just as much as the water column. It creates a mat to cover it's food source to keep it all to itself and it can feed on nutrients from freshly made saltwater. High flow isn't a cure it's more for preventing since it helps keep detritus in suspension to be mechanically removed because if it settles it's a perfect place for cyano to make its home. I have some live rock that has been dry for 10 years that I started re curing a few months ago. I have it on my porch where there's sunlight and it has cyano growing on it even though it wasn't introduced by frags or fish
