I am two years out from a velvet wipeout. I removed all surviving fish for copper treatment, fallowed 76 days, and now nothing goes in my DT unless it can survive therapeutic copper and observation in QT for at least 30 days. And... my DT is a dream. Not a spot on any fish. I used to buy fish all the time. LOL, I think I am permanently out of the market now. I miss going to my LFS. But my fish are indestructible; I now focus on coral. I see so many posts of people adding garlic, or ruby reef, or peroxide, or metro, or kick ich, or other nonsense, and sure enough they post again, and again, and again, about parasite trouble. It is actually very simple. Parasites cannot spontaneously generate, and they cannot survive therapeutic levels of copper (or CP) for the prescribed time period (I would err on the side of max dosage). End of story. I never realized how much buying fish, again and again, and replacing them, again and again, used to be a part of my life. It was a nightmare. I may never buy another fish. Which is kind of sad. But I see these hobbyists stuck where I used to be, and there is SO MUCH resistance to the hard work. I know everyone has a different experience and opinion, but success stories not involving the above (fallow, copper, QT) are few and far between, but with so many success stories from that protocol. So I want to add my experience/story to the list. Fallow, copper and QT. Your life will change. I don't care if you "don't have space to house all the fish". But two Brute tubs. This isn't rocket science.
So, if you are stuck in ich/velvet hell: Please read up on the sticky posts from experts like Humblefish. This hobby is only hard when it comes to the corals. The fish are a breeze, but you have to follow the protocols. Eradicating parasites from fish is a walk in the park compared to the ten million factors that go into getting acropora to grow! Now for that, I am all ears...
