I was wondering that does anyone have the elements list that spirulina need?
For example when we have “ferrous sulphate”, does spirulina need sulfate also or only ferrous=iron?
And how about “sodium bicarbonate”: does spirulina really need sodium, we know it need carbonates so it wont need CO2 from the ambient air if I understood right.
CO2 has two oxygens: we dont need that. NaHCO3 has three oxygens, so is there a reason why we cannot crush wood charcoal and feed it to spirulina as source of carbon?
Someone please provide just the basic chemical elements that spirulina needs to grow like this:
We need to cook up simple soup in ordinary natural basic things, so everyone can grow spirulina even in Africa without hygienic problems with biowaste, manure etc.
I mean simply, that wood ash has many elements useful it also raises pH. And how about if we add clay to the culture, red clay in Africa has much iron especially.
Spirulina can float in the culture and adjust its position with gas vacuoles/vesicles. Clay and ash particles will fall to bottom when not mixed. So we dont need continous mixing of the culture. And when we mix it, it will release nutrients from the sediment of clay and ash.
So what else we need?
Using animal wastes is simple when you burn them to ash.
But when we dont have animals, how we can cultivate spirulina? There is always some wood and therefore ash: also soil of somekind.
Lets figure out, how we can cultivate spirulina the most simple yet effective.
If you are new to subject, here is something to start with:
Just first thought: do we really need chloride elements for spirulina? Or do they even, affect the growth in negative way?
What happens to chloride-element when we give the spirulina calcium chloride?

Chlorine in algae (and in fertilizer!)
This just does not add to me..
As also in here it is stated, that clorine is bad for algae but in the same text they say - calcium chloride should be used as fertilizer.
So I think, this is one main reason - yet no-one seems to talk about it, that in chemical fertilizers, we cannot ever have the maximum yield, since for example chlorine exists in such great amounts in fertilizer:
"We use tap water, filtered through activated carbon (such as a Brita) or through a ceramic filter (such as a Berkey). Algae are quite sensitive to chlorine (which is why it’s used in the first place!), so tap water is only usable if the chlorine has been removed—which can be done using products sold for fish aquariums.
The afore-mentioned filters, and de-chlorination, leave minerals in the water, which is generally a good thing; if you want to use de-mineralized water such as distilled or reverse osmosis water, or if your water is particularly soft, you may get better growth if you add some combination of 0.1 g/L magnesium sulfate, 0.5 g/L potassium sulfate, and/or 0.1 g/L calcium chloride (or lime or plaster). That said, we have yet to hear of anyone having trouble growing in non- or de-chlorinated drinking water of any kind."
Did any one ever find natural basic supplies of nutrients for spirulina? I am new to growing spirulina and am looking to do it naturally, however there is not much information out there on it! I would also love this possibility to a population in Africa and you had mentioned Africa. Did you bring it there?
