Marine Macro Algae - Aquacultured

Marine macro algae refers to several species of macroscopic, multicellular, marine algae.  The term includes some types of red, brown and green macroalgae.  Two specific environmental requirements dominate macro algae ecology.  These are the presence of marine or seawater and the presence of light sufficient to driver photosynthesis.  The strong photosynthesis of algae creates a large affinity for nutrients; this allows the seaweed to be used purposely to remove undesired nutrients from water. Nutrients such as ammonia, ammonium nitrate, nitrite, phosphate, iron, copper, as well as CO2 are rapidly consumed by growing seaweed. Reefs and lakes are naturally filtered this way (the seaweed being consumed by fish and invertebrates), and this filtering process is duplicated in artificial seaweed filters.
