Is it Cyao?

I think I have cyano but I wanted to see if I could get a confirmation. At first I thought it was diatoms (2 mo old tank) but some spots are stringy and have a couple bubbles attached at the tip. I got a microscope off amazon but it want much help. I do have a conch who seems to be enjoying himself on the sandbed and since it's not a massive outbreak he seems to be doing fine with it. It is constant throughout night hours. Phosphate is 0 which I assume is because the algea is taking it all up, I had to order more nitrate stuff for my checker off amazon (didn't realize I was out), ph is 8, salinity is 1.025.

While the microscope photo is not clear, the color and the existence of individual cells point to diatoms or dinoflagellates.
