UltraPlanktos Z CWM is a concentrated suspension of five different types of marine zooplankton, and four types of marine-derived food particulates, all ranging in size from 50µm - 2 mm and having an extremely diverse nutritional profile, rich in a number of fatty acids including the omega-3 fatty acids EPA, ARA, and DHA, as well as in carotenoid pigments, vitamins, minerals, and several important amino acids. Omega-3 fatty acids and pigments have been shown to provide tremendous benefit to the overall health and coloration, respectively, of planktivorous organisms. Additionally, the particulates are infused with a blend of free-form amino acids that encourages feeding response in fish, and improves coloration in Cnidarians. UltraPlanktos Z CWM is a complete food complex for planktivorous fishes and motile suspension-feeding invertebrates inhabiting temperate (“cold water”) marine aquaria. For feeding of temperate marine sessile invertebrates, UltraPlanktos P CWM provides a suitable size range of phytoplankton and marine-derived particulates to ensure that nutritional requirements of those organisms are satisfactorily addressed. Does not require refrigeration. Maintained free of contaminants and stored in a cool location, has maximum effectiveness within four (4) years of the date of production. Not impacted by temporary freezing.
