1.88ug/l copper in rodi

[Nano10]

I recently sent in a ATI ICP test due to tank issues with no apparent cause and the only thing that stood out was 1.88ug/l copper in my rodi sample. Yet my display no detectable copper.

I know the rodi icp test in and of itself doesn't necessary mean anything as far as effects on your display, but I was wondering if I should be concerned or not?

Bump...id be concerned.

Iirc copper forms complexes with organics and might be skimmed out by skimming. However how long that takes might be enough to cause issues.
