hey guys, so im currently dosing my 10g QT with copper power and using an API test kit ive currently dosed 13ml which should be 2.2ppm of copper in the water but the API reading is only slowing about 1.0 ppm would anyone be willing to let me barrow their Hanna for a single test? or know if any fish stores new Bergen county can test for copper?
