A concentrated blend of marine zooplankton designed to provide the essential fatty acids, proteins, vitamins, amino acids with biological carotenoids for coral growth. Particle size ranges from 12.5 - 500µm to feed a broad range of marine aquarium inhabitants. Contains a natural source of carotenoids which provides essential proteins as well as a more bioavailable source of pigmentation when compared to other natural sources and synthetic pigments. Carotenoids provide the extra benefit of antioxident activity. In addition, it is enhanced to increase the bioavailability of important nutrients such as proteins, lipids, B vitamins, and other organic pigments, thus, corals expend less energy to derive the nutritional benefit from this food. Blended to contain the proper ratio of fatty acids, carbohydrates, and proteins. Blending phytoplankton has also been shown to yield better nutritional value.
