nitrates are 0 because they are being processed by the cyano, you could have dinoflagellates which eats nitrates as well and is more characteristic of the bubbles all over the place.
dino is more photosynthetic, it is less noticable at first light and gets worse as the lights are on and almost disappears at night, dino is more toxic than cyano and usually requires a lights out period of 3 to 5 days, reduced flow, no water changes and heavy skimming to erraticate.
ID is difficult as it is often mistaken as cyano.
