A highly-concentrated suspension of Nannochloropsis, Tahitian Isochrysis, and Tetralselmis, contains over 12 billion cells per ml (~1.2 billion cells per drop). Rich in EPA, DHA, and amino acids for maximum benefit to marine invertebrates. Size range of phytoplankton (2-15 µm collectively) is optimal for feeding a wide range of filter-feeders. Properly preserved, contains no alcohol; Requires no refrigeration or freezing! Directions: Add 1 drop (0.10 ml) per 50-gallons to an 8-oz. container of aquarium water, stir, and add this to the aquarium every other day.
