Use this quality food grade Sodium Bicarbonate in normal baking, food making or as a component in your own Spirulina medium. In most standard Spirulina growth mediums in between 5 to 20 gram per liter of Sodium Bicarbonate is used. The scientific standard medium ”Zarrouk’s medium” uses 16. 8 gram per liter. With using the highest concentration these 500 grams will be enough for 45 L Spirulina medium.

During growth, the Sodium Bicarbonate contributes most of the carbon, beyond what comes from the CO2 in the air, used by the Spirulina. More Sodium Bicarbonate can, therefore, be added to the culture in intervals to give more carbon and enable more growth. However, more Sodium will at one point slow down growth and at around 60 gram Sodium per liter a normal culture stops growing. There is 27.4 % Sodium in Sodium Bicarbonate. At these concentrations of Sodium Bicarbonate, a pH of around 8.6 to 8.8 depending on water source is reached. As the Spirulina grow and the culture become denser the pH will rise and finally end up at around pH 11 – 12. At this point, the culture will stop growing. Spirulina grows fastest at a pH in between 9.5 and 10.5 at a temperature of 35 to 38°C.
