Help IDing what I think are Dinos, not sure

[CoreyT355]

I posted the other day about my declining tank, with a couple pics here, https://www.reef2reef.com/threads/tank-in-a-downward-spiral-need-some-help.865588/#post-9466039

I got a cheap microscope today, and did my best to look at several algae samples from the tank. I'm not 100% sure if this is dinos or not, and if so which ones they may be. Hoping someone here can confirm if they are or are not dinos at least. Which ones would be even cooler, so I can battle them better.

Looks amphidium dino
Siphon up and net loose particles
Clean filters and skimmer and reduce or turn off white lights
I’m about to board company jet and will be in air almost 3 hours but will send recipe for Dino when I get home
