Microscope video of unknown creatures/dino/diatoms

So after beating amphidinium via silica dosing and more nutrients as well as phosphate, some months later i find myself battling ostreopsis, much worse looking but since i'm running carbon i haven't seen any toxic effect whatsoever.

The thing is, a couple of days after dosing, my glass is now flooded with diatoms. It's incredible how fast they reproduce. I could only find a single ostreopsis in this sample.

But on top of diatoms i'm seeing some really tiny fast swimming things that i couldn't identify and look nothing like the amphidinium i had before but swimming almost like them

Here is an ostreopsis for size comparison 400x

Small cell amph maybe?

I did have small cell, and could swear they looked different, they had something that resembled a mouth.

While these look a bit different no mouth shape whatsoever but an irregular tip

Is the biofilm on the glass green or brown? That looks like an organism I've seen frequently that seems to be some type of green algae and not a pest.

I never seemed to find much ostreopsis on the glass when I had it, mainly on the rocks/sand/powerheads. If you don't see any gross evidence of it, I wouldn't be concerned about 1 cell on a slide. I would be willing to bet if we sampled every healthy looking tank we would find an occasionl dino/ostreopsis.

Yes the ostreopsis were mostly on the rocks. Although it has subsided by now due to my aggressive silica and nutrient dosing.

But i was curious about the other creatures, it was a brownish stuff on the glass
