sera Micron is the rearing food close to nature that even the smallest and most fastidious aquarium animals (fish and amphibian larvae, Artemia shrimps and others) in fresh and marine water like to eat. This finely powdered food optimally resembles natural plankton in its contents (50% Spirulina and 16% Krill, among others) and structure (dust fine particles float in the water) and supports healthy growth, disease resistance as well as optimal development and color formation. The water is not unnecessarily polluted due to its excellent digestibility.
