Diatoms? Dino? (ID help)

[whyapollo]

This comes from a newly setup tank. I had the dry rock and water "cycling" in a container for about a month before add them to the tank. At that time I added the "live sand" (the kind purchased in bags). Few days later, added some fish, and fed heavily. Weeks later, added cheato and pods..
I think that's where I got this brown stuff from. I took a small sample and put it under a microscope and got this video.
Can anyone help ID them?

Unfortunately- I can't see the video/picture. If the OP could upload it with YouTube it would help

Image looks like diatoms.

How can you see the image - on my browser its just a gray square?

Did you stain those with something? Dinoflagellates are usually motile (unless dead) - Diatoms usually look more 'symmetric'. Can you show a picture of your tank? (i.e. where did you find them)

Mine too!

But the video posted works.

Yep, and I find it sometimes will work when it’s not YouTube but sometimes not…technology!

Here's some pics of what's on the sand. There's also one of a rock closer to the light.
I haven't stained them, I think its the microscope camera that made it so dark.

Looks like diatoms and what is called the “ugly stage”

Clumping together like that... I am saying Dinoflagellates. I just siphoned some off the sand in my classroom reef and showed the students this past Wednesday. FWIW

Diatoms are more golden in color, and have a silica covering called a frustule. With diatoms you would see a bunch of different shapes and sizes of frustule.

There are some diatoms mixed in
