We get the numbers that are considered "NSW".
e.g.
Alk 7.7
Ca 420
Mg 1270
Those are my basic understanding of what is generally considered "NSW".
As to the original question where do these numbers come from? Are they an aggregate or average? Are they from a specific area of the ocean like say the fore reef?
Curious as to where these numbers come from because my ocean water collection is showing something dramatically different. I am trying to see if there are other factors involved. Perhaps seasonality or tides.
One interesting thought though is that the Alk is dead on each time that I test at 7.7dKH. This is confirming my growing understanding that the Alk should not change ... not even a little bit.
Thanks in advance for any help.
