Question

I have a water ionizer to make alkaline water - do I need to put minerals in the tank?

Community Answer

It would be a good idea. Spirulina, like other living organisms, requires a variety of minerals to sustain life. A water ionizer alone will not provide all these.

There are many formulas that you can use to enhance the growth of your spirulina culture. Different minerals and ratios would produce a different end product. Do a google search for "grow organic spirulina" and click on the first link. That website has many different recipes you can choose from.

Question

Can I start a colony with dried tablets of spirulina?

Ditsa Keren

Community Answer

Unfortunately, no. Because spirulina is a live cyanobacteriu, you need a live mother culture that can grow and multiply as single-celled organisms do. The drying process, whether done naturally under the sun or using an industrial spray dryer, kills any living bacteria, including the algae itself. To find a live spirulina culture from a supplier near you, visit grow-organic-spirulina.com.
