Spirulina Nutrient Calculators

Our online spirulina nutrient calculators were designed to quickly estimate the amount and ratio of the nutrients used in a number of popular spirulina culturing formulas. They address both the initial inoculation stage and the ongoing maintenance of the culture, particularly after harvesting.

Select your preferred nutrient composition from a number of popular formulas and get precise recipes for your culturing media based on the volume of tank and the amount of spirulina biomass you harvest.
