I have been battling Dino’s for couple months now. I have used a microscope and identified them as Amphidinium. I have tried everything to get rid of them. Daily sand vacuuming and manual removal. I have dosed beneficial bacteria (microbacter 7). I have tried multiple black out periods and still no luck. I have lost a couple corals to this. 0.08 phos 19.1 nitrate was parameters last time I checked. What else can I do to get rid of this??
