Dinoflagellates or Diatoms?

I’ve been battling what I believed was dinoflagellates and thought I had them under control. I recently acquired an old microscope from a family member who is a retired science/physics teacher. I am by no means qualified to be even handling a microscope let alone attempt to identify what I’m looking at. I was hoping that someone here could assist me in identifying what I am seeing. After researching some photos on the internet I believe what I am seeing is Diatoms.
I recently killed what I thought was Dinos with Fauna Marin DinoX which worked wonders and made the tank look pristine initially. Two weeks after the DinoX treatment was finished, I started to get some red and green hair algae (mostly red) which is a first for me. Did my water changes and added fresh GFO and even continued with H2O2 dosing and the hair algae’s have been slowly dying off.
This weekend I started seeing some of the brown dust starting to cover the sand bed and glass and started to freak out. If it is Dino’s it is not full blown yet and if it’s just diatom’s a few more water changes and some more GFO should solve the problem.
Tank is 1 year old, RODI filters just changed less than a month ago (0 TDS). I use RS Coral Pro salt
Salinity – 1.026 (refractometer)
Nitrite – 0
Nitrate - 0
Calcium – 440 (red sea)
Mag – 1300 (red sea)
Alk – 9 DKH (red sea)

Thank you Docstach! I saw the same link which led me to believe I was looking at Diatoms.
