Potentially (probably) Dinos?

[jsanchez]

Any help with identifying this crud? Pretty sure it's dinos but I also have some red and purple cyano going on. This is on my gyre. It's all over the sand and back wall as well. The snails will eat it and the fish do pick at it. The stuff loves to grow on my chaeto.

Pics from the organisms on my gyre.


These pics are from what I believe is cyano on the sand bed.



And this is from the stuff growing on the gyre.



Was hard to get a good zoomed in pic, the most common organism I see is shaped like a seed and rotates like a plane doing a barrel roll.

Any help would be appreciated. Pretty sure it's ostreopsis dinoflagellates but it doesn't seem to go away at night.

seed rotating is dino. ostreoposis is usually like a tether ball rotation

Yes, I see dinos there in the last pic. Looks like ostreopsis to me.

Raise your nitrate and phosphate quick!
