About this item
Natural Rock Chaetomorpha Refugium Macroalgae (Chaeto)
Natural Rock Chaetomorpha (Chaetomorpha sp.) is a unique form of chaeto macroalgae that grows directly attached to porous reef rock, forming a dense, anchored green turf. Unlike traditional floating chaeto, this structure creates a stable and contained nutrient export colony within the aquarium.
This growth form is especially effective in refugiums and nutrient management systems, where the anchored structure prevents tumbling and drifting while continuing to efficiently absorb excess nutrients from the water column. It provides a clean, organized alternative to loose chaeto masses while still delivering strong filtration benefits.
Available Options
Small Rock Colony
- Small rock with Chaetomorpha growth attached (~1–2")
- Ideal for establishing Chaeto in refugiums or macroalgae zones
- Allows the colony to expand naturally from the rock surface
Large Rock Colony
- Larger rock supporting a dense Chaeto colony (~3–4")
- Immediate nutrient export capacity
- Suitable for established refugium systems

Special Considerations
🌱 Propagation
Chaetomorpha spreads through fragmentation and filament expansion:
- Loose strands may grow into new clusters in high light and flow
- Colonies expand outward across rock surfaces
- Harvesting portions promotes continued growth and nutrient uptake
