Dinos? chrysophytes? ciliates? ID possible?

[pookie]

ive posted this in a few areas now and nobody can idtentify them and now im here hoping someone can identify them. They move very fast under the scope and have taken over my sandbed. This sample was taken at 250x i can re take samples if need be. It seems after 5-10 minutes all of these "cells" die off and seem to "split open" more photos below of what im talking about and what they look like in the tank. Ryan Thompson told me to post on here to hopefully get an ID. I really just need to know if its toxic and the right way to get rid of them if need be....

g someone can tell me what these are?

Can confirm after 1 hour and 15 minutes they disappear off the sand bed... seems like dinos more to me but this isnt the common type i dont think...

The video definitely looks like some kind of dinoflagellates moving around. The other attached images look like something else. Have you taken a look at this thread yet? https://www.reef2reef.com/threads/dinoflagellate-identification-guide.671466/
I'm not the best at identifying what kind of dino but if you get some good magnified images maybe someone else can help.

I can’t see the video and I’m sure many people as well. Can you post it on YouTube and link it here ?

I can’t see the video. The scope pictures don’t look like dinos to me but the sand bed might be dinos. Your description sounds like dinos.

If your corals and other inhabitants are doing well I’d try to not worry about it and do normal maintenance. If that’s not the case, I’d read up on a UV sand sweeper and think about trying that.

And, if others can see the video, then maybe you’ll get more clarity.

Here you guys go. Im pretty active in a fino identifying group and none of them are what this is.

It’s not magnified enough. Can you do 400x ?

In my experience, Dinos do not rapidly move around. If the image looks like a swarm of flies, I'm going to assume not Dinos. Ive got both LCA and Ostreopiss Dinos at the moment and none of them behave like that. However, the sand bed looks like Dinos lol

Those 3 videos are at 1000x

That’s pretty cool. I have no idea what they are. But at their metabolic rate, I don’t see them being around very long.
