Join me as I set up two new tanks (a 30 and a 40 gallon) to grow Spirulina, including discussion of the recipe medium, which is the secret sauce of farming this superfood algae. See the complete medium recipe at !

In this, part two, we use green tea as a chelating agent to chelate iron from iron sulphate. I also tease a bit the idea of using a compost heater to maintain temperature in a Spirulina tank. It’d take a ton of tinkering, but beats using 2x150W heaters 24/7!

And see also Part One: for all medium ingredients and tank setup for farming Spirulina:

And Part Two: Chelating Iron for the medium:

The iron sulphate elixir, which I might not use again if I can find PURE iron sulphate without sugar and coloring in it, is here.

Finally, a peek at the tanks after one week, when it’s time to turn on the lights:
