Hello
I'm quartining a couple of fish and am treating them with cobrasal for copper treatment (I'm in the UK and copper power is not easily available, have some on order but will take a month to get here and need something right now). Then thing is what level of copper should I run with this should it be 2ppm or lower. I see another thread has different levels for different types of copper so not sure if it should be this high or lower at 0.25 ppm.
