I downloaded the new phreeqci graphical interface and ran a test example through. When compared to the results i got from running the same example through wateq4f and netpath, i came upon some unusual errors. Firstly the charge balance, or percent error, was off by more then 8%. As well, there seemed be some errors in carbonate speciation(about 10x smaller). This then affected the IAP's of the calulated phases (mostly related to carbonate). With wateq4f and netpath bicarbonate is entered, however using the interface it looks like you enter carbonate concentrations. What confuses me is that when the input appears C(4) notation is used, which I thought was for bicarbonate. Am i missing something? I entered by bicarbonate concentrations and got errors, should i be entering carbonate concentrations?
