I would like to enter multiple transition metals and trace-elements and SO4-, Eh, and pH into GWB, and have it work out which metal sulphide will precipitate first due to decreasing Eh at various pH's. Is this possible with Act2? My only progress so far are mosaic diagrams but they really just overlay two diagrams and so leave out many other possibilities.

Probably to best way to do what you describe is to trace a sliding Eh path with React, and then use Gtplot to diagram the results.
