So, here is my full "spirulina" equipment:
- a 0,7x0,6x0,25 full butcher's tray almost to the brim,
- a small solar "stirrer" made from an old disassembled hi-fi system and powered by a small solar panel taken from a Chinese HS fence energizer (photos available on request).
- a large pass,
- a marble slab for drying
- a pitcher
- a thermometer,
- Sunflower paper for pH
- white wintering fabric to shade if necessary.
- and of course, the eyes, nose and fingers.
That's it that's all !
Illuminated tank exposure but without direct sun, culture pH between 10 and 11,5 in brackish water.
We give "food" according to what we take (harvest approximately every three days on average in good season).
The "eat" is urine or nettle manure, iron salts (rather citrates if possible) and wood ash.
It is also necessary to have baking soda which is used to balance the pH and to provide dissolved CO2, which "boosts" the growth of algae.
The whole art consists in finding a sampling / feeding rhythm adapted to the conditions of the moment (lighting, temperature, etc.).
With a little experience, it is done very well "by feeling".
Here ! I hope it will give ideas!
