Around what percent would mag/alk/Ca raise per point of salinity? Real world example, I tested my Mg last night, its at 1155, too low. I then tested salinity, and it is also too low at 1.024. Rather than add magnesium, I will let the salinity come up by a point or two. Im just wondering around what the Mg DKH and CA will raise up to when I raise the salinity to lets say 1.026. Is there a general rule of thumb, like 10% per point for example?
