Porphyridium is an easier to grow red algae, seems fairly hardy and has a bright pink red hue. Higher airflow is critical for this culture, lower airflow causes the cells to clump and the culture to crash. Known for its fatty acids, lipids and polysaccharides for color enhancing properties. Has a high concentration of phycoerythrin, zeaxanthin (carotenoids), phycoerythrin (accessory pigment to the main chlorophyll, color enhancing cells), ALA fats (Alpha-linolenic acid), EPA fats (Eicosapentaenoic acid). Unique properties of this phytoplankton is the polysaccharides are sulphated. Porphyridium is commonly used in the aquaculture community to bring red colors into other filter feeders, like marine rotifers & copepods. Porphyridium also has a high concentration of antioxidants. 

This strain is grown at 1.023 salinity and Fritz F/2 fertilizer currently. We use 2ml of each part per culture volume. This red phytoplankton does well on UPS 2 day shipping.
