Help with microscope ID of algae

[Reef AquaCult]

LINK TO VIDEO

Appreciate any help. I had a turf algae issue after going fallow x 76 days. Then I added fish back in and feeding schedule changed. How it looks like I have cyano vs dinos on top the turf algae. I took a 100x video with light microscope.



Parameters
Temp 79F
SG 1.026
Alk 8.2
Nitrates 0 at the beginning now keeping 1-3 ppm
Phosphate 0.00 - 0.10 depending on day (Hanna)
Bare bottom setup x 9 months old tank
Running lights 12 hour schedule

It looks like in the video there are mobile unicellular organisms that I believe are dinos. I’m not sure if the long strands are cyano or turf algae. Species help with dinos would be appreciated. Thank you!

The 3 large circles look like Coolia dinoflagellates.
The strands look like cyano possibly.
The tiny, numerous spots could be chrysophytes, or some other type of planktonic stuff.

Coolia dinoflagellates and cyano for sure.
