Can someone check this scope video out for ID?

I have some brownish stringy algae on the sand bed. Here’s some scope pictures with a link to the video. One person said diatoms already but I’d like to get that confirmed. Thanks!

Hard to tell from the blurriness. Does it look like this?

Here's a good source for common items under microscope.

Thanks for the link. It does most closely resemble that but not exactly. Here’s another pic of the only two guys that we’re moving around. I believe they’re the same type of thing, one is just brown and the other is clear.
