ICP ANALYSIS Arsenic?

[sp1187]

I just got my test results back.
Doesn't the highlighted results mean something needs to be fixed?
If so, what do I do about the arsenic?

Arsenic is sometimes detected in some salt mixes in trace amounts. From what I remember it’s not a necessary element for corals. To humans it is highly toxic and deadly in larger amounts, but hardly detectable in sea salt. Not enough to harm anything.

What I don’t get is why the reading shows it red when ICP recommends it be 0.
