Dino ID request and a confirmation on diatoms (?)

[JaxBeachBrian]

Hi everyone - I am currently in the middle of a battle - 7 days in - with Dinos which came after dealing w/GHA (via ReefFlux) & bottoming out on nitrate/phos. Wanted to see if someone could clarify or confirm what I'm seeing.

Here's some initial info:

The tank: IM 112 EXT w/37g sump
What I am doing currently:

• Running 24W Green Killing Machine UV 24x7
• Dosing nitrate with a target of ~10
• Dosing phos with a target of .10
• Dosing silicates (SpongeExcel) with the intention of inducing a diatom bloom

I think I can now see diatoms alongside dinos in the microscope - could someone confirm if the dinos are Ostreopsis and the smaller rice-shaped things are diatoms?

Good deal and thanks, appreciate it.

In the gif & attached video w/dinos, do you think the smaller things are diatoms?
