I have some in Anaheim if you want to grab it tomorrow. It’s at my office so wouldn’t be able to get it to you until I’m at the office tomorrow.
I wouldn’t worry much on that reading on the Hanna. At low levels the Hanna Cooper Test is not very accurate.
I was worried about a month ago about the same thing and Hanna was showing 0.36. Did an ICP before running Cuprisorb and it was not detectable on the ICP.
