Can I reuse Biological media that has been used in a QT tank with copper power?

[QuarantinedCorals]

Hi everyone, hope you're all doing well! I recently treated a couple fish with copper power in my quarantine tank, however, the quarantine tank used to be my main display so I left half of my biological media in that quarantine tank and added copper power to the system (copper levels register at 2.0 ppm). I really want to add that biological media that's in my quarantine tank to my new display because its about a year and a half old, well established. My question is, is it safe to use the biological media that's been exposed to copper? Does the biological media hold onto the copper power? how can I go about removing the copper from the bio media?
