Is this dinoflagellates?

That's what my money's on, but these have been a nuisance for months, so I thought I'd confirm with some more experienced eyes. Thanks.


(also I don't keep my lights like this all the time, I just couldn't get a good picture with the blues on)

Looks to be cyano to me.

I think you might be right; thanks. I was thinking dinos cause of the stringing (hard to see but somewhat apparent in the second image) but it does look more cyano-y to me now that you mention it. I've had dinos before, so I suppose I just thought it was the same thing.
