Collection: Macroalgae

Live macroalgae for refugiums, planted marine displays, and reef tanks. Macroalgae competes with nuisance algae by pulling nitrate and phosphate out of the water, gives copepods and amphipods a place to breed, and adds natural color and movement to a display.

Our lineup ranges from hardy, fast-growing green macros that are ideal for nutrient export to showy reds and iridescent species grown for display. Some varieties are also available attached to live rock or in bulk for larger systems.

Macroalgae ships out Mondays & Tuesdays, with insulation and temperature packs as needed.
