I used a tank to quarantine fish with copper before.I soaked the tank in vinegar and the only thing I’m reusing is the sand. I ran a cuprisorb for a week. I tested with Hannah checker and it’s .11ppm.
I have a live rock with coralline that I purchased but I want to know when it’s safe to add my first coral/invert. Tank is fully cycled, but with trace copper.
I’m using the hannah HR copper checker and it can register 0.02ppm in a fresh tank with copper never added.
