i just finished treating my sick tank with cupramine for ich - had lost two fish so pretty serious, i was doing 50% water changes (not with my tank water, that was infected) 2-3x per week and was dosing the new water and my top up water with cupramine to recommended levels - i did this by working back the ratios to the volume being used from the recommended amounts on the bottle and checked with a seachem copper test kit, i treated for the recommended time then kept the fish out of the display for 8 weeks total , no ich has returned two months later
thats what worked for me.
