I supposedly, as told my my local pool company, have 2PPM of Copper in my pool. I think they are drunk. But, it's the only pool company around that tests for copper. So, I want to know what test kit or strips others are using to determine Copper in pool water so I can test myself. I see the Taylor test kit that TFT has only tests to 1PPM. We don't seem to have any discoloration or staining or green hair or anything...but, I'd like to determine the levels and proceed accordingly. Thanks for the advice in advance!
