What is nutrient dosing?
In some marine macro algae dominated systems, there are simply not enough nutrients to sustain growth (nitrogen, phosphate, iron, etc.) This is true of seagrass planted aquariums which need large amounts of nutrients to thrive. The addition of Nitrates or phosphates should only be administered in a closed planted system and is not recommended for refugiums. There are several freshwater supplements available, as well as our own lab quality mix. It is believed that adding iron also aids in the growth of macro algae and marine plants. This can safely be added weekly to any system lacking this nutrient.
