Black and White Particles Floating in my tank…?

[Biggest Little Reef]

Before the lights turned on in my 10 gallon euphyllia tank yesterday and today, I noticed about 20-30 of these black and white particles floating around in my tank. It’s really hard to get a picture of video of them, but they are black with a white tip and cone shaped. I turned off the return pump (no power head) and some seemed to float to the top, some just stayed suspended, and some sunk in a spiral motion.

My tank is 100% euphyllia with a clownfish pair, a yellowtail damsel, and a handful of snails including astrea, trochus, cerith, and nassarius.

What could these particles be? And should I be concerned?

Maybe buds from one of your euphyllia. Any of them look damaged or unhappy?

I'm using chrome on my mac. Maybe that's why it's working for me? I don't know. I barely know how to keep a reef tank, forget about computer stuff

I uploaded these videos from my phone. They seem to be working fine for me in the Edge browser. Anyone else able to see the videos? Have any thoughts?
