Caulerpa

Caulerpa prolifera

Also known as Flat Caulerpa, Blade Caulerpa

PlantaeChlorophytaUlvophyceaeBryopsidalesCaulerpaceae

📍 Mediterranean, Caribbean, Indo-Pacific

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.
