When you get your own sample tested your results are compared to this "perfect" datum.
They give you the results with a traffic light system highlighting what elements require action if any to bring them in line. Green being good, Amber and warning, and of course Red action required. The is a document called the error correction sheet which details the remedial actions.
If you receive if Red "high" alarm then the usual action is dilution via a WC with either Triton Pure Salt, or a known good salt brand. If you are using another salt brand however it should be noted that as a lot of brands run at elevated levels some of the other elements will be effected. This is why they came up with pure, because it is just that.... It contains nothing else. If however copper is detected then a product called Detox can be used which is basically a binding agent for copper which is then in turn removed via carbon.
If on the other hand you receive a red low then the action could be to do the individual element. In my personal tank the only addition element I dose is iodine.
I hope this goes some way to answering your question

I expect your iodine is not a useful additive, but that's just my opinion. You never dose calcium or alkalinity?
As to my questions, I was hoping for a more detailed answer.
Since Triton cannot measure down to NSW levels of many trace elements, I'm not sure how you can use natural levels as a guide, and the numbers they show as the target are often not the natural levels anyway. Iron, for example.
Do you expect me to believe that Triton measured trace elements all over the place, and got the exact same average of 0.1 ppb for 13 different metals on their list?
So, clearly the setpoint is not the NSW level of many of the trace elements. Hence, the "traffic light" is based on something else, and I've yet to clearly hear what that is.
This is why they came up with pure, because it is just that.... It contains nothing else.
Nonsense. If you look hard enough you'll always find every element in seawater or aquarium water, real or artificial. So the claim must be that this mix has equal to or lower than NSW levels of trace elements, or else it could not be used to lower things to NSW levels. With that as the requirement, I'd like to see the evidence of that, especially since Triton cannot detect down to NSW levels. So somehow they will have to use different tests to verify the "pure" than they use on aquarium samples. And if it turns out to be lower than NSW in everything, how could it be useful as it will lower everything, whether it is too low or too high? You use it, then add back everything that got lowered to far?
I'm familiar with copper binders. Not with tin. So my question is how you lower tin. Or cobalt. Or mercury. Without lowering the others. Water changes may work, I agree, but may need to be done on a regular basis.
