About the ORA Sea Lettuce Algae
Care Level: Easy
Reef Safe: Yes
Minimum Tank Size: 10 Gallons
Ulva lactuca is a thin flat green algae. For the refugium, sea lettuce makes an excellent fast-growing nutrient exporter, and doubles as food for herbivores and copepods. Lettuce can exist in a refugium without being tumbled in high circular flow, but does best when it spins and all areas of its biomass are constantly exposed to light and nutrients. This algae can tolerate both very low and very high light levels, and can live through hypo-and hypersalinity treatments in quarantine and hospital tanks.
