Notes: The most popular nutrient "scrubber" in marine refugiums. The mass of thick filaments captures nitrates and phosphates very efficiently. It is harvested by removing portions of the mass. There is no risk of sporulation. Amphipods and copepods reproduce among its filaments, providing a source of live food for the main aquarium.
