Size ranges from 1-20 µm to feed a broad range of tropical marine aquarium Filter feeders and invertebrates. Reef phytoplankton 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 antioxidant activity. In addition, reef phytoplankton 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. It is blended to contain the proper ratio of fatty acids, carbohydrates, and proteins. Blending phytoplankton has also been shown to yield better nutritional value. Ingredients Water, Sodium chloride, Thalassiosira weissflogii, Acetic Acid, Isochrysis sp, Ascorbic Acid, Citric Acid, Nannochloropsis, Astaxanthin Directions Shake well before using. Add 1 capful (5 mL) per 200 L (50 US gallons) of water twice weekly or as required to maintain coral growth.
