Phytoplan is a spray-dried blend of several strains of phytoplankton. The intact cells aren`t living, but when rehydrated, they are a microencapsulated source of color-enhancing beta-carotene and astaxanthin pigments, vitamins, amino acids, and essential fatty acids. A concentrated food, much more economical to use than live phytoplankton. High in DHA. Ideal for filter-feeding invertebrates like soft and stony corals, anemones, feather duster worms, clams, sponges, and tunicates. PhytoPlan simulates food webs in closed aquarium ecosystems and, with daily addition, promotes the development of zooplankton. Soak dried foods in PhytoPlan to boost nutrition value.
