By growing this macro algae in our systems, it out-competes other nuisance species like green hair algae and Cyano Bacteria (red slime) for the nutrients in the water. Thus this algae is great for keeping those unwanted destructive algae at bay or even non-existent in the tank over time. Keep in mind that the more light lumens it gets the faster and healthier it will grow. What we mean by absorbing nutrients in the tank is that by growing, it is using the nutrients in the tank for food or fuel as we sometimes refer to it. So the more it grows the more it can filter the water.


We prefer this saltwater algae for all of our filtering systems because it is the safest.  Most other algae can go into a sexual faze and start releasing gametes  and some inhibitory chemicals which all combined in an enclosed system, can really foul your water up almost overnight, before you know what happened.


This algae is unappealing as a food to many of the reef fish, so you can grow it in your main tank or in a refugium/sump type of setup.
