Copper in my DT help!!

[Randy Holmes-Farley Verified Community Expert]

could the lingering copper be leaching from my rocks?

It could be, but it might also now be test error. I’d try that kit on some new salt water.

Ok I will ask them to see if they can sample the new water. I am sending an out an ICP soon I just wanted to get a 0 reading on the hannah before I did

The reason that I asked is that the Hanna is known to read copper at levels like yours when none is present.

Hence, test it on new salt water that presumably has none.
