The Seachem Nourish Supplement for Fish is a multivitamin, Amino Acid, and trace element supplement designed to meet the nutritional needs of freshwater ornamental fish kept in closed systems for an extended period of time. Nourish contains Potassium iodide in a Spirulina and Chlorella base. Iodine is required for the biosynthesis of Thyroid hormones; Thyroxine and Triiodothyronine. Spirulina and Chlorella both have a high concentration of amino acids and vitamins. Nourish can be used on marine ornamental fish, but it is primarily intended for freshwater fish.
