Chaetomorpha Macroalgae

Chaetomorpha Macroalgae, often referred to as “chaeto,” is a highly beneficial, fast-growing algae prized for its role in nutrient export and overall system stability. Its dense, wiry green strands form a loose, tangled mass that provides excellent habitat for copepods and other microfauna. Under strong lighting, chaeto grows steadily by absorbing excess nitrates and phosphates, helping to naturally reduce unwanted algae in the display. It thrives in moderate to high flow, which keeps it gently tumbling and prevents detritus buildup. While simple in appearance, a healthy ball of chaeto is one of the most effective and low-maintenance tools for maintaining a clean, balanced reef system.
