Dino ID confirmation

[Richard Terrell]

Hi All!
I have what I'm pretty sure is a dino outbreak in a client's tank. I let the nitrates and phosphates get to 0 for too long and well...Anyway, I just wanted to see if I can get a consensus on the ID. Pretty sure they're Ostreopsis.
Thanks in advance!
Rich

Doesn't look like ostreopsis to me, maybe amphidinium? A video would help a bunch. If you could post it in the Nuisance Algae forum our resident expert taricha should be able to help with ID.

Thanks. I could post a video but they're not moving that I can see. The sample was taken Wed night and I just got to look at it today.
