Copper is an essential trace element for all forms of life that we know of. NSW contains approximately 0.25 to 0.75 ppb of copper your copper is high relative to that but I suspect that the source of copper is your salt mix. Check your RODI and then your saltwater mix. The commercial salt we use to culture our nitrifying bacteria has ~100 ppb of copper in it. Our biggest problem is getting enough active copper in the culture media so we add 1.0 ppm of it to the media. Not suggesting that you do or don’t have a problem but if it is in your salt mix and your tank is doing well, then I would not worry about it.
