Thanks Brian. This was helpful.So in new model there is no checkbox for "water limits" as its written in minteq database:
"Visual Minteq does not include H2(g), thus the config->options->"water limits" checkbox for GWB programs Act2 and Tact needs to be unchecked when using this dataset"
I have another question related to GtPlot.
In Eh-ph diagram plots some of the species overwrite each other. I have attached one of such plots. Is there a way to separate them?
Thanks again.
