Exactly Dave, Hence the reason for a balanced system chemically and not just adding chemicals without testing or shooting for max saturation without regard for the final outcome. In small system this can spell disaster very quickly. That was one of the reasons I talked about matching the Cal, Alk, and Mag for water change saltwater.
If you are keeping your system at lets say for example alk 10.5 dkh, Cal at 430 ppm and Mag at 1300 and you do a 20% water change and that new water is alk 8.6 dkh, Cal 380 ppm and mag 1200 ppm it could cause precipitation and also effect the corals in a negative way. IMO one of the reasons you may here people saying that after a water change my system looks worse than before I did the change. But I think we are getting off track.
I hope between the advise we gave we helped these guys get their systems back in line.
