It appears to be Ostreopsis - due to the spinning. I fought these for 5 months and came out the other side. Take a look at this thread - it is kind of the Bible around here for fighting dinos. Good luck! https://www.reef2reef.com/threads/dinoflagellates-–-are-you-tired-of-battling-altogether.293318/
