ICP test results

[Wolters_88]

Just got my results back and it’s not looking good. Copper is at 3.59 and I have no clue why. Aluminum is 16.21. Zinc is 45x higher than it says it should be…. Should I do a huge water change?

Copper at 3.6 ppb is not likely an issue, assuming it is accurate. Mine was above 10 ppb when I measured it myself.
Overall the icp looks fine to me.

Ok, some of those saying it should be zero and then having measurements was worry some. Thanks.
