I had an outbreak of ich or velvet in my display tank and lost several fish. I set up a QT to treat my remaining two fish (copperband and melanarus wrasse). Since the wrasse needs sand to sleep in, I added some from my display tank to a tupperware in the QT. I wasn't thinking about the fact that the sand will likely have the parasite and it would have been best to add new sand. Am I okay to leave the display tank sand in the QT since I will be running copper? In other words, will the copper kill any parasites in the sand anyway? Obviously I won't add the QT sand back to the display tank once the 76 days fallow is complete.
