I suppose a possible result of any c-dosing is a dinoflagellate bloom, and I am starting to see them. Skinny strands of reddish / brown that grow straight up and trap bubbles. I see just a strand here and there, and do my best to baster them out when I can.I have been feeding (too) heavily as of late, so will likely cut back as much as possible on that, continue to suck it out, and make up some water for a change this weekend.
From an article re: dinoflagellates - ReefKeeping Magazine:
“Dinoflagellates are widespread in nature, and vary considerably in their habits. Some are free floating, photosynthetic organisms and are classic phytoplankton. Others can become symbiotic photosynthetic organisms living inside corals, clams and other marine organisms (i.e., zooxanthallae). Some dinoflagellates are parasites on fish; still others are predators. These are often larger than typical dinoflagellates (up to 2 mm long), and they move through the water consuming smaller organisms. Some dinoflagellates are bioluminescent, and others release toxins (e.g., red tide toxins) that can travel all the way up the food chain to humans. “
