Live Chaetomorpha Chaeto Macroalgae Reef Tank Refugiums

Looking for live Chaeto macroalgae for your saltwater aquarium or reef tank refugium? Our healthy green Chaetomorpha macroalgae is an easy, natural way to help manage excess nutrients while adding biological diversity to your aquarium system.

Chaeto grows by consuming nutrients such as nitrate and phosphate from the aquarium water. As the macroalgae grows, portions can be harvested and removed from the refugium, physically exporting those captured nutrients from your reef tank.

Each order includes a generous large portion approximately the size of a softball, giving you an established amount of Chaetomorpha to start or replenish a refugium.

Why Use Chaeto in a Reef Tank?

• Helps naturally consume nitrates and phosphates
• Excellent for reef tank refugiums and sump systems
• Provides additional habitat for copepods and other microfauna
• Fast-growing macroalgae that can be periodically harvested
• Helps compete with unwanted algae for available nutrients
• Easy to maintain with appropriate water flow and refugium lighting
• Large approximately softball-sized portion

Chaetomorpha is one of the most popular macroalgae choices for reef aquarium refugiums because it grows as a dense, tangled mass rather than attaching itself to your rockwork.

How to Use Chaetomorpha Macroalgae

Place the Chaeto in a dedicated refugium, sump chamber, or macroalgae reactor with moderate water movement and an appropriate refugium light.

Allow water from your aquarium system to continuously move through or around the Chaetomorpha. As it grows, periodically remove a portion of the algae to export the nutrients it has absorbed.

For healthy growth, Chaeto needs:

• Appropriate refugium lighting
• Regular water movement
• Available nitrate and phosphate
• Adequate trace elements and nutrients

Growth rates will vary depending on your aquarium's nutrient levels, lighting, flow and water chemistry.
