What am I looking at? (Dinos?)

[jvjWonka]

Hello all! First post and first serious tank. My tank is 4 months old, I’m seeing what I believe to be Dino’s. I have had very low nitrates and phosphates so increased feeding to help raise them. Bought a microscope to help identify what kind. But I have no idea what I’m looking at lol. Any help or guidance would be greatly appreciated!!

Tank info:
Red Sea Nano Peninsula
HOB Refugium
ATO
Dosing tropic Merin all for reef
Added galaxy pods, Tiger pods, dos live phyto daily

If you can post some still photos of the microscope field there are some folks on here who can help id the stuff.

Video is not working for me.

The cells in the video are diatoms (triangular/pointy) Also that large hungry beastie is a ciliate. they eat bacteria and tiny algae cells.
