OK, unless anyone disagrees, I’m about to make up the following:
- 0.56 g/L NH4HCO3 1 -
Entirely Ingredients - 1.05 g/L NaHCO3 -
Dr Oetker - 2.3 g/L KH2PO4 -
APC Pure - 2.9 g/L Na2HPO4 -
APC Pure - 0.5 g/L MgSO4⋅7 H2O -
Health Leads Epsom Salts - 0.01 g/L CaCl2 -
Intralabs - 1 pill/L Vegan Multivitamins & Minerals with High B12, D3 & K2 -
Vegan Vitality 2 - Make up to 1L with raw water 3
The next big question is then whether I should start the culture with 100% culture media rather than adding it gradually to a sample of pure raw water that we electrolyse. I'm thinking the former otherwise the ionic strength may be too low for successful electrolysis.

1 to give the same mass of NH4 as 0.47 g/L (NH4)2SO4 - please check my maths
2 see https://forum.amybo.org/d/25-trace-element-solution/3 for further discussion of trace minerals
3 rather than risk washing out the bugs should the chemostat flow be too high, I'm thinking of making up the initial culture media with the raw water that we're enriching.
