Need help with ID nuisance algae cyano or Dino?

[brandon2950]

Last two weeks my take has been taken over by this ugly stuff and I’m not positive what it is and I do not want to take action if it is the wrong ID and course of action. If anyone could help me figure it out I would greatly appreciate it! Thanks in advance!

Difficult to be absolutely sure from those pictures, but it looks like Dinos.

Or Calothrix, can look similar to Dino’s.
