Sharks and rays with copper

[kws82590]

I want to start off by saying i currently do NOT have any shark or Stingrays in my system but i was wondering is even small traces of copper deadly to sharks and rays? I’m currently getting a reading of 30ppb or .03ppm of copper in my system.

It depends on what form the copper is in. If this is residual copper from a treatment with an amine-based copper medication (coppersafe or copper power) that would be completely safe. If it is from ionic copper, there could be an issue in that the upper limit I like to see with that is 0.05 ppm.

Don't forget - your 0.03 reading (on a Hanna test?) could be at the lower limit of the testing range, and you also need to factor in the accuracy of the device.

Copper power was used and i was using the Hanna low range tester witch reads in PPB i tested three times in a row and all three test were between 30-35ppb
