We culture over eight different species of phytoplankton (Tetraselmis, Nannochloropsis, Isochrysis, Thalassiosira weissflogii, Nannochloris, Chaetoceros, Chlorella, Dunaliella, Porphyridium and Pavlova) separately and then combine them after harvest to insure that aall eight species are present - if cultured together, one will eventually eliminate the others. This blend has green, brown, red, and gold with cell sizes from 1 micron to 14 microns. Some are motile, and some are not. They all have different nutritional profiles. In short, this blend should provide feed for all of the various phyto-consuming organisms in your tank.
