Bicarbonate?

[supahotfire]

Hi,

I just got the water report from my town but bicarbonate was missing.

So I opened up brewfather and filled in what i could and noticed that i did not get a alkalinity value.

The alkalinity in my water is 60 and to get that number i played around with the bicarbonate value until i reached 60 alkalinity in brewfather.

Is that a method that works or am i totally wrong?

I don't use Brewfather, but the answer to your question would depend on whether the software's calculated "Alkalinity" is "as HCO3" or "as CaCO3." If you are sure that the software's calculated "Alkalinity" is in the same units as your water report's, then yes, your method of backing into the Bicarbonate value should work. If it's not, you'll need to do a conversion.

If the software Alkalinity is expressed "as HCO3" but your report's alkalinity value is "as CaCO3," multiply your report value by 1.22. The result will be the "Alkalinity" value to hit when tweaking the unknown Bicarbonate number.

If the software Alkalinity is expressed "as CaCO3" but your report's alkalinity value is "as HCO3," divide your report value by 1.22. The result will be the "Alkalinity" value to hit when tweaking the unknown Bicarbonate number.

Looking at your screen captures, it looks like Brewfather's computed Alkalinity is "as CaCO3."
