first a big THANK YOU for developping PHREEQC, which has lead me to a lot of better understanding.
I'm calculating equilibriums in seawater and, as you say in the manual, this is a bit beyond the possibilities of PHREEQC. On the other side, there are examples provided with PHRREQC which include seawater. So, what do you think is the approximate error I have to expect ?
For example, if I compare calculated ion speciations to Millero's "Chemical oceanography", my results agree with Millero's for most ions (like Na, Mg, K, Ca). But for Cu++, I calculate 93.2 % Cu(OH)_2 and 5.5 % CuCO_3, while Millero says 73.8 % CuCO_3, 14.2 % Cu(CO_3)_2-- and 2.2 % Cu(OH)_2.
