Help ID Dino please

[FrancoNot]

Good evening all, my tank is 14 months old and everything was doing fine.
Parameters are stable:
Alk 9.3
Cal 430-440
Nitrate 15-20
Phos 0.07
In the last 3 weeks i had a cyanobacteria and dino bloom.
The cyano are covering the sand and the dinos are on the top portion of my scape on the rocks.
Before addressing the cyano i need help ID what kind of dino i have so i can deal with them first.
Here are some pics and video under microscope. (sorry for the shaking but i do not have a phone holder)

Thank you all for your help.

That looks like Coolia to me. A "rare" one :D

You can see it swimming similar to Ostreopsis, but it's nearly spherical and has deep grooves.
