Chaetomorpha Algae, also known as Spaghetti Algae or Green Hair Algae, is an excellent macro algae for refugiums. Each cell grows from end to end creating long, stiff strands. It grows in filamentous clumps, resembling a ball of fishing line. Cheatomorpha is a fast growing, hardy algae that is normally grown in a refugium where it absorbs nitrate and phosphate from the water as it grows. In addition, this algae is a great habitat for microfauna such as copepods and amphipods to reside and populate.
Chaetomorpha Algae removes both phosphates and nitrates from the water. To increase the amount of nutrients these algae export, use moderate to high lighting and keep it in an area with high water flow. Ideally, tumble in an algae filter.
