Full-spectrum vitamin supplement formulated to benefit marine fishes, corals and other invertebrates, and other marine aquarium inhabitants. Provides a full-complement of vitamins in the same ratios found in the tissues of filter-feeding marine invertebrates, organisms that extract plankton from the surrounding water and gain their nutritional benefit, and which are in turn consumed by many reef inhabitants. Requires no refrigeration. Composed of purified water and ultra-high purity materials. Formulated by a marine scientist.
