fuel™ is a comprehensive carbohydrate, vitamin, amino acid, polyunsaturated fatty acid, and trace element supplement developed to address nutritional requirements commonly associated with corals. fuel™ contains ascorbic acid in a base of chlorella, which contains a rich assortment of amino acids and vitamins. The health benefits of chlorella are widely known and while spirulina, a similar algae, has been regularly used in the industry, aquavitro is the first to utilize the vastly superior chlorella. fuel™ is formulated to provide nutrients available from natural tropical reef waters. Chlorella is a unique algae that grows in fresh water. It is extremely high in enzymes, vitamins and minerals, including the full vitamin-B Complex.
