Through advanced research and innovation, Cobalt created a premium fish food that takes fish nutrition into the 21st century. These Spirulina Flakes promote health, color and digestion in fish. It features naturally occurring probiotics bacterial strains Bacillus subtillis and Bacillus licheniformis in a concentration of 1000000 CFU/g in every flake. This helps reduce the amount of waste produced, and prevent clouding of the water. Special enhanced blue flakes provide a combination of triple-vitamin boost and natural immunostimulants that strengthen a fish's biological resistance to disease.
