Great info and probably wishful hoping it was FA. Some more questions
1) Will this Cyanobacteria die over the winter ?
2) once you have it is it likely to come back each year? Never had this previously.
3) would you recommend I stay away from the cutrine plus and go with the aquashade and good bacteria supplements and treat it as it shows up with options you described above?

Thanks again for the help. Very informative.
