Note: copper can NOT kill ich encysted stage (egg). That’s why we need to treat fish for copper for 30 days before we can lower the therapeutic copper dose because all the eggs would have hatched and been killed.
So why is fallow 76 days? If there is a strain of ich that can last that long, why isn’t it recommended to transfer the fish to a sterile tank after 30 days from a therapeutic dose copper?
Note:
We can be confident that all of the ich/velvet would have fallen off fish after 14 days. So transferring from 14 day full copper to sterile tank can shorten treatment to 14 days in lieu of 30 day copper…but for simplicity for discussion, let’s just use the standard 30 days because it’s the eggs that are going to hatch after 30 days when copper that’s sub therapeutic that I’m worried about.
