How long do you leave fish in the treatment tank?

[Dusky]

Hi!

I wonder how long you leave the fish in a treatment tank after they were sick, when can I put them back into a medicine free tank?
I know I should leave the DT fish free for atleast 6 weeks (I'm treating velvet or Brook).
But how long do I leave my fish in copper? On Facebook someone said only 1 week, but only after removing 20% of the copper in the tank (by doing a water change) the spots came back and I had to start treating again!
They're in copper for 2 weeks now ( 3 weeks of you count the first failed attempt)
How long should they stay in the copper? Couldn't really find something online about this.
Many thanks!

I would leave them in copper for 30 days and then observe them for at least another 30 days after meds are removed.

I don't use cooper as I think it is dangerous, but that's another topic. I do TTM/Prazi-Pro for 15 days, then into the QT for 7-8 weeks with a preventative treatment 21 days of CP.

I used 'trimarin' which has this as ingredient list:cuprum 2+ 9.2mg , ethacridini lactas 5.0mg and proflavinae 0.7mg in a 20ml bottle.
I'll have a look into prazi pro, hope I can find it in my local shop (I live in Belgium )

Cheers
