I haven't seen dinoflagellates before... I need to find out more about that.Awesome things are starting to look up for you! Lacking colors may likely be due to your 0 nitrate reading. Be carful with the super low nutrients. I just went through and still going through issues due to that. You don’t want any dinoflagellates popping up.. It’s a nightmare! I have to dose Nitrates and occasional phosphates it keep readable levels.
