Seachem Nourish – Vitamin, Amino Acid & Trace Element Supplement

Everyday nutrition support for fish in closed systems.

Aquarium fish live in closed systems that can't fully replace the vitamins, amino acids, and trace elements they'd get in the wild — gaps that show up as dull color and lower vitality.

Seachem Nourish is a comprehensive supplement of vitamins, amino acids, and trace elements in a heavy base of spirulina and chlorella, with potassium iodide for healthy thyroid function. Designed for freshwater ornamental fish, and usable on marine.

Nourish reflects the science-driven approach Seachem has taken since it was founded in 1979 in Madison, Georgia. As a chemistry-led company whose products are developed and manufactured in-house by chemists and backed by research, Seachem formulated Nourish as a concentrated, balanced blend of vitamins, amino acids, and trace elements built to fill the everyday nutritional gaps of a closed aquarium.
