From what I read about the life cycle of ich, they usually fall off the fish in 3 days but can be 7 days as well in some cases. And 4 days for velvet.
Assuming worst case 7 days scenario and if we are transferring fish to a sterile environment afterwards, why do we need to treat fish with copper for 14 days. Wouldn't 7-8 days be enough?
