Depending if I set the check box “Specify acid by target mash PH” to check. Or if I set the amount to the same number calculated I get a different result in the HCO value. Checked I get a HCO value of 264. When I specify the acid to the same amount calculated by the calculator I get a HCO value of 123. Nothing else is changed in the calculator. This can’t be right? If specify acid is selected, I get recommended to use 14.93 ml lactic acid Result: But if I set the amount of acid to 15 ml, nothing else changed I get a different result in the HCO value?
