Use in aquarium keeping Marine fish, corals, and a variety of invertebrates acquire vitamins directly from the surrounding seawater, as well as from ingested food, so addition of BioViv M directly to the aquarium is beneficial to both. When feeding marine fishes, consider adding BioViv HUFA along with this product to supply essential Omega-3 fatty acids, EPA and DHA as well. Vitamin deficiencies can be responsible or a contributing cause for diseases in marine animals, just as in humans. It is prudent for the hobbyist to pay close attention to the variety, and quality of foods for both fishes and invertebrates, and the addition of BioViv M will help make sure that your animals get the vitamins that they need without overloading the aquarium with unwanted ingredients.
