The dino clump up id method was described in this thread very early on by myself.
Since then my dinos do not behave that way any more so it's not a good method if you need to be certain.
I've also gone the Kalkwasser route with all the evaporated water replaced as Kalkwasser and it does not work for Ostreopsis.
Microscope is the way to go and there is a high chance of identifying the type of dinoflagellates at the same time.
Dinos and Cyano look very different in a microscope and are also easy with a little practice with the naked eye.
