Are these diatoms?

[Aquajan]

Hi,

Two weeks ago I have set up a coral quarantine tank with water and some rock from my main display.
Now the bottom is covered with a brown film and I would say they are diatoms what would make sence as it is probably going through a mini cycle..

But I recently bought a microscope to id the red stuff I'm my main tank (was cyano) so now I have used it too to see what the brown film is.
I'm not experienced with a microscope but i would say it are diatoms with bacretia feeding on them.

What do you guys think?

New tank diatoms. Lightly siphon bedding as needed

Ah nice thanks.

Are they all diatoms? Or are the guys with the long needle shape diatoms and the rectangle shaped guys bacteria?

I think all we see there is only diatoms. You know they build up something (slime) to keep attached. I think that's what the rest is on the video.
What's the zoom on your Microscope ?

Ok cool, I thought it was an algae or something.
It is 400x zoom, any more than that and the vield of view gets so narrow it is almost impossible to see something.
