I have to say that I am believing the variety of dino in my tank is not especially toxic, at least from a chemical standpoint. I can see how they would smother corals though. I can't help but wonder if they have an extremely short lifespan? Every morning the sand seems way less covered by brown, only to have the "bloom" rush back bigger and badder than before. If on the other hand they simply launch themselves into the water column at night perhaps UV would help? It does seem like I killed off one of their limiting factors, specifically competition. The simple green algae like you might expect to scrape off the glass seemed to disappear when the dinos showed up.
