It's been a little while, but if I recall correctly Cupramine treatment should last 3-4 weeks. The only time that the parasites are susceptible to the copper is when they are free swimming or attached to the fish. If they are in their cyst form laying in the substrate, the medication will have no impact on them. Again, this is why it is important to treat for the full 3-4 weeks.
