You can eradicate ich or you can manage it. You promote managing it. I promote not having it. And you are correct that more fish suppliers are having more issues, but these are issues with their systems, not issues with the wild fish from the ocean. If suppliers would properly maintain their systems, we would not see so many sick fish. And I am a biologist/scientist. Two degrees and 34 years experience. But it doesn't take a rocket scientist to understand the life cycle of ich and how to eradicate it. And the fact that we are having more sick fish is exactly why I state you should QT fish. We will have to agree to disagree, but I will never put a fish that has been in your tank in mine. Peace.
