Tried posting this yesterday but never saw it....

Hi Jeff,
Previous post you mention;

MgCl2-6H2O 0.2 g/L (Magnesium Chloride or road de-icer)
NaHCO3 0.25 g/L (Sodium Bicarbonate baking soda)
KHCO3 0.125 g/L (Potassium Bicarbonate)
CaSO4-2H2O 0.035 g/L (Calcium Sulfate Gypsum)

This adds 8 mg/L Ca++, 69 mg/L Na+, 24 mg/L Mg++, 34 mg/L K+, 258 mg/L
HCO3-, 70 mg/L Cl-, & 20 mg/L SO4-.

Can you recheck "K" ? I did the math and get 48 using your recipe.
Here is how I did it;

0.125g/L of KHCO3 = 125ppm
Molecular weight of K is 39.01
Formula weight for KHCO3 is 100.1

125 x 39/100.1 = 48ppm of K or 48mg/L, not 34mg/L.
Can you please recheck. All other numbers I checked OK.

I imagine the extra bit of K you get from your recipe 48,
as opposed to the ideal for tanganyika 34.2 is also no big deal.

The HC03 at 257 seems a little below ideal of 344.
Can you comment?
