I have been dealing with dinoflagellates so I stopped dosing vodka and after a few months I started dosing neo nitro to raise nitrates to 8ppm. Less then 4 cap fulls added to my 240gallon tank. After 2 months all of a sudden my tank tested at 67 nitrates so I sent a test to triton and it came back at 101 nitrates! Phosphates up to .68! I still have dinoflagellates (Amphibinum) and crystophytes. One thing I did do was swap out my sump. In the process I pulled all my old sand (2lbs) and mineral mud (6lbs) from my old sump and replaced it with 10lbs of new live sand. I'm debating weather to start carbon dosing again to lower the nitrates. My thought process is nitrates this high is worse than Amphibinum. Any insight or ideas are welcome
