YOu have a good point and the only way to be 100% sure is to put a cup of carbon runing in loop wit a small filter to make sure the water is really going through it, in a bucket with like a gallon or half a gallon of water for a day, then analyse that water. in my own test it reached .358 ppm which is 3 times the dosage to kill ich. with this test you can be 100% sur that if there is copper in the carbon the common test is going to tedect it easily.

If that come out negative, it was not copper in the carbon. If it does contain copper in large quantité like mine, then you have the culprit right there and a sample should be sent by mail to the company.
