Bryopsis
Bryopsis sp.
Family: Bryopsidaceae
📍 Worldwide in tropical and subtropical seas
Feathery, fern-like dark green algae that is notoriously difficult to eliminate — one of the most persistent reef tank nuisances. Resistant to most herbivores. Best controlled by raising magnesium to 1500–1800 ppm for 2–4 weeks (magnesium treatment). Sea hares will consume it but are not a permanent solution.
