[edit] Overview

A green, hairlike marine alga, Chaetomorpha linum forms dense masses of tangled strands that provide haven for myriad small invertebrates.

Aquarists have discovered its usefulness, placing it in well-lit sumps or refugia, where it grows prolifically, extracting dissolved organic wastes from the water and acting as a spawning ground for desirable crustaceans such as amphipods.

It is replacing Caulerpa spp. macroalgae for such uses, being more productive and banned in states such as California, where Caulerpa is feared as a potential invasive species in coastal areas.
