Reef Genetics Phytoplankton – Tisochrysis lutea

Tisochrysis lutea is a golden-brown phytoplankton species prized for its high DHA content and small cell size, making it a staple in reef nutrition. Whether you’re gut-loading copepods, feeding filter-feeding corals, or maintaining a nutrient-balanced microfauna base, Tiso delivers highly bioavailable nutrition in a clean, aquacultured form.

Cultured in-house as part of our Reef Genetics program, it’s harvested fresh and bottled clean to deliver reliable performance across display tanks, refugiums, and home culturing systems.
