Diatoms or dinoflagellates?

[Vertigo916]

Been having a diatom bloom for well over a month and now I'm thinking I might have dinos, not diatoms. So I bought a microscope and attached a video. Are these dinoflagellates? If so what kind? I googled images and videos, but i don't trust my eyesight. Tank is almost 3 months old. Nitrates are 5ppm, 0 ammonia, 0 Nitrite. I don't have a phosphate test yet. Thanks for any info.

The ones that look like rice grains are diatoms. The others look like dino. Post pics/ videos on macks dinoflagellates page on Facebook. Best resource for identifying and treatment
