The Delhi Mix, also known as the RM6 formula, is a modified version of the commonly used Zarrouck formula, specifically designed to lower the production costs of commercial spirulina cultivation units.

Why we created this manual?

Spirulina can be quite sensitive to changes in the climate, quality of air, and nutrient compositions present in the water. While different cultivation methods are available, most documentation on growing spirulina is written with scientific terminology that most people aren’t familiar with.

Our online calculators simplify the research process by focusing on what matters most: the numbers.

Whether you’re growing spirulina in a raceway pond, a photobioreactor, or just an aquarium, knowing the exact nutrient proportions needed in YOUR facility makes it easy to experiment with different growing methods and choose the one (or more) that suits you best.
