The 32 elements that they test for on the ICP are also tested on NSW samples, I don't understand why you think they don't? Yes maybe the make up of the water in the reefs off Australia may be different to the waters of Florida but to take a mean figure from the many 1000's of samples they have collected over the years has got to be a good enough place to start. I mean not many reefers keep one specific biotope, many corals from all over the world living in the same water conditions. The set points as far as I am aware have come from the research that they did and are doing, if they decide that to replicate certain water conditions in enclosed tank is not favourable or easily achievable then who knows they change the number a bit? ..
I am surprised that you think that the set points might actually be real NSW results. You think that all 13 trace metals might just coincidentally have come out to 0.1 ppb?
There's just no possible way. The set points are even below the stated Triton detect limits for some elements, like Mercury, for example: the Triton Limit of detection for mercury is claimed to be about 0.7 ppb, and the set point is 0.1 ppb, and the NSW value is about 0.001 ppb. How could they possibly measure that and report it?
So the set point necessarily is something else.
