How often can I harvest my spirulina?

Depending on the density of your tank, you can harvest 2 – 3 times a week. We recommend you harvest at the beginning of the week and refrigerate your spirulina so that you can skip the harvesting and eat your spirulina right away. You can reach higher density if the spirulina’s environment is 95 – 98 F (35 – 37 C). For a reference, check out the images on our website.
