I need help identifying Dino’s through my microscope

[malcb76]

Please help identifying the microscopic photos that I believe may be Dino’s. ( The Round shaped organisms). They seem to disappear overnight (or maybe not? so I’m suspecting Dino’s, but no strings or bubbles at all. I have lowered lighting for over a month now and the sand bed has gotten better, issue seems to be resolving. No UV installed yet. I run a skimmer , reef mat 1200, 2 MP 40s, 3 Radion XR 15s. Thanks for your attention !

525xl running over 8 mos
Nitrate 6.8
Phos .11
Cal 430
Mag 1350

The still image looks like bits of stuff with maybe one cell present.

That’s consistent with the other slides I looked at. Is the cell Dino?

It does not appear to be a dinoflagellate. Maybe just a random protozoa.
