Recently, after running vibrant for two months to knock out a bunch of bubble algae, some green slime has found its way onto my sandbed.
I assumed it was the beginnings of cyano, but my understanding is that cyano is typical for low nutrient systems. My PO4 is typically 0.08 - 0.1, and my NO3 is typically 15-20ppm. I have been nopox dosing to bring these numbers down.
Note that I have also been dosing phyto daily, and under the microscope, this looks suspiciously like the phyto I have been adding.
Am I farming phyto in my DT?
