Copper Levels in QT!

[PapaShrimp]

Just in a moment of panic here, thought I knew what I was looking for with cupramine QT treatment but just dosed first dose and now not sure.

I am running a 90 litre QT tank. Just put 40 drops of cupramine in as it says 20 drops per 40 litres.

Used Hanna Copper HR checker and it came back at 0.30ppm.

now i read that I am aiming for 0.40 to 0.50ppm for cupramine but then just read somewhere that a reading of 0.38 would kill fish quick!

can anyone help and advise if I have an issue on hands and if I should quickly lower levels?

Thanks
PS

Pretty sure the effiective concentration of cupramine is .25ppm , but I could be wrong. I know its .5mg/l for a final concentration.

0.5 is the therapeutic dose for cupramine, perhaps a bit lower but should aim for 0.5. If it dropped for a shorter period of time it may not be an issue but observe your fish.

Thanks for the info mate. I thought that before dosing and then panicked due to it being the first time I have used copper in a QT I will aim to raise it to 0.5ppm in a couple of days time. Bottle says keep it like that for 14 days, would you recommend any longer than that as I see some run for 28 days with copper?

I would raise slowly to close to 0.5. If you are going to transfer fish to a clean tank, you can do that after 14 days (I normally do 3 weeks). If you want to keep your fish at the same tank, you can remove copper after 30 days ( I normally do it 6 weeks ).

Thanks for the advice. I take it the additional time if keeping in the same tank is incase any Ich virus etc that has detached and isn’t dead yet reattaches after copper levels drop?
