Caulerpa

Caulerpa prolifera

algaesaltwater

Fast-growing macroalgae with flat, oval blades on creeping runners. Excellent nutrient export and refugium algae. Can go 'sexual' under stress — turning milky white and releasing gametes, causing a tank crash. Keep under 24h light or harvest regularly to prevent this. Widely available and very effective.

Chaetomorpha linum

algaesaltwater

The most popular refugium algae in the reef hobby — tumbling masses of stiff, wire-like bright green strands. Grows rapidly, exporting nitrates and phosphates as it's harvested. Provides a habitat for copepods and amphipods that migrate into the display tank as live food. Extremely hardy.
