I kind of rushed this tank and dont really know a lot about what you said exept for quarantine tank and copper. I dont have an extra tank lying around or rodi water so it will take until morning but until then my lfs will prob open and they have a lot of quarantine tanks so i can put the clown there. Will test also
Are they actual QT tanks and not connected with eachother? If they are connected, every time a fish enters the system, the clock restarts for QT
