3.4 oz Tetra. Starter Culture

Give your reef the nutritional boost it deserves with our 3.4 oz Tetraselmis Starter Culture, grown fresh in-house and inspected under a laboratory-grade microscope to ensure quality, density, and purity. Known for its rich lipid content and natural swimming motion, Tetraselmis is a favorite for pod growers, coral keepers, and home phyto culturing.

Why Our Tetraselmis?
