Brown bubbly snot - possible Dinos

[Soppe]

Morning crew

Nutrients bottomed out and I'm getting those guys back up.

In the meantime looks like Dinos have taken up residence. I took a look at the guide and I'm not entirely sure what specific kind they are. Could you take a look at the attached pictures and give me a hand?

In the afternoon/evening they're stringy snot looking guys, with bubbles, and they do disappear at lights out.

Thank you

Hey! I am unsure the name right now but being these are the ones that disappear at night, they are easy to remove. Correct, bump the nutrients up, add some beneficial bacteria as well. I've had this happen once or twice a long time ago and for me i killed the "whites" on the light (just ran blue), kicked up the flow a bit, opened the skimmer but reduced it to on for 17 hours, giving 4 hours for the bacteria to work. Also UV will help but not necessary. That's what worked for me, others probably have different methods. Good Luck.

I suck at IDing stuff but they look like Prorocentrum to me. How (and how much) are they moving under the scope?

I've had Ostreopsis, but those are more "pointy" and spin on their own axis...so pretty easy to tell based on the movement.

Thank you. I'll take a look at a slide tomorrow and look for movement.
