yes! 100% to do copper you will have to take the fish out and put them in a small QT tank. Copper should not be used with corals or inverts. I wouldent even trust it with my LR or LS. You can get a cheap 10G tank from wallmart with the filter and heater. You will have to cycle that tank with some or your water and some fresh water. that is the best way to do it. |
