Lee,
Today is the last day of the 14 day cupramine treatment

and all is well! I have successfully kept the copper level in the acceptable range.
Tomorrow, the 15th day, I plan on performing a water change and adding a polyfilter to begin removing the copper.
I have not seen an ICH spot on any of the fish since about the 2nd or 3rd day of treatment. Yay! They will remain in the hospital tank until December 24th (another 5.5 weeks) to ensure my main display is fallow for a full 8 weeks.
As long as I do not see any signs of ICH within this 5.5 weeks, I will know that the treatment was successful, correct?
Also, I want to deworm them using prazipro and metronidazole sometime before 12/24.
Is it safe to use both medications at the same time? When is the best time to deworm them? After a week or two of rest from the copper treatment?
