Hey guys, sick of ick so i'm setting up two 20L QT tanks to copper treat my remaining fish. I am using seachem's cupramine, it says to dose based on 2 weeks but I was under the impression I need to treat the fish for 6 weeks and leave my display tank fallow for 8 weeks. Any advice on the process would be greatly appreciated. I have PVC hiding spots for both tanks along with air pumps/powerheads for oxygen, along with heaters. Any input is greatly appreciated it has been surprisingly difficult to find information on the process online.
