As you know , Randy, I have to disagree. I will give you that a properly designed two part system can very closely approximate the ionic balance achieved by the Balling Method. But I strongly disagree, and feel it is a very misleading statement to say, that the well designed two part system accomplishes "exactly what the Balling Method does in terms of ionic balance"! The ONLY way it could do that is if it contained ALL 70 (let's not argue about that number, I'm rounding off) of the trace elements found in natural sea water. And I don't know if ANY two part system that does that.
