ID on these guys?

I’ve been fighting ostreopsis and today I started to see some strings in the cyano that’s started to take hold. Thoughts?

I would possibly think they are Dinos of some sort... not entirely sure!

Hope some others chime in and help out!

Those aren't ostreopsis dinos moving around so quickly in the video... they look like small cell amphidinium dinos to me by the movements.

I can't really see the "threads" clearly in the video. Best to post pics that can be blown up and looked at without movement... the video is over before anything can be focused in on.

I agree on Amphi . Prepare by starting with a water change and blow this stuff loose with a turkey baster and siphon up loose particles.
Turn lights off (at least white and run blue at 10-15%) for 5 days and at night dose 1ml of hydrogen peroxide per 10 gallons for all 5 nights. If you dont have light dependent coral- turn all lights off.
During the day dose 1ml of liquid bacteria (such as bacter 7) per 10 gallons.
Clean filters daily and DO NOT FEED CORAL FOODS OR ADD NOPOX as it is food for dinos.
Day 5,, you can start with blue lights - ramping up and work your white lights up slowly
