flanque, check out this article.
I too think you are suffering for a Dinoflagellates (which, like cyano
, isn't a true algae) rather than cyanobacteria. The article reccomends a few solutions that have worked for the pros and researchers, as well as a deeper description as to what it is.
I would most definitley consider the addition of snails to your clean up crew, perhaps an urchin as well. I'm hesitant to suggest and Algae Blenny, mainly because they are hard to care for. But boy they control algae well.
My advice is to remove all that you can physically first, either suction or scrubbing it off. Remember if you scrub it off to still try and remove all you can, then do a water change. (Dying algae can just just as bad for the tank as dying fish). Black the tank out for a few days, and try running some activated carbon or phosphate sponge. I agree with melosu that the reason your tests are showing up 0 for both nitrate and phosphate is likely because the algae is consuming it so quickly.
and dinoflagalletes are the only O2
producing "algae" that I know of. Usually cyano
forms in thicker sheets with less bubbles. Dino usually forms in somewhat thinner sheets, much more bubbles. Usually.
