Agreed. The species in the North East is Alexandrium fundyense. It seems like what we deal with in aquariums is of the genus Ostreopsis. For the most part it seems like making the water "dirtier" helps to keep Ostreopsis at bay. I've been doing that (no water changes, no carbon, the gfo, etc.) then nuking with FM Ultra Algae X. 7th dose tonight, dinos about 90% gone, corals fine, fish fine. Algae growth on glass has come to a hault. Fingers crossed...
