Triangle shaped algae/Dino’s? (Micro scope photos)

[a.t.t.r]

Any ideas on what the triangle shaped ones are? They just appeared today. I am hoping some type of diatom.
Additionally now that I have a better scope any idea on the actual species of Dino?

the diatom is probably licmophora and the other cell I am guessing is prorocentrum dino.

Yep. Right on both accounts it looks like. So glad I am finally getting diatoms been dosing Po4 and silicate for a bit now. Stupid vibrant wiped out bio diversity in my tank and been fighting this junk ever since

Looks like a diatom. Here is a great facebook group to help with dinos and diatoms. https://www.facebook.com/groups/259474048655429

I beat dinos just dosing silicate and a bit of po4 even though i never got nitrates to be detectable on tests, the dinos just went away in a couple of days with the help of my strombus too lol. Now i found this thread because all of a sudden i got this pizza looking diatoms all over the tank. Not sure what to do about it.

Found any solution?
