Common Name:Caulerpa

Scientific Name: Caulerpa

Caulerpa is common in the aquarium hobby as a nitrate absorber because of its rapid growth. It is a green algae which sends out runners and will grow leaf like structures that will look more like long leaves. The ‘leaves’ can grow as long as 4 inches and up to an inch wide. Caulerpa is a great algae to grow in a sump or refugium for nutrient removal as it will quickly remove nitrates and phosphates from the water out competing many other forms of algae for these same nutrients.
