New Salt...I am happy for you and your tank that it appears that your problem with Ich is over. There are a few people who feel that garlic can eliminate Ich, but there are more that have tried it, found some relief, only to
find that the Ich recurs in the future. I hope that is not the case with you and your tank.
At some point in the future I hope that there will be scientific studies comparing many of the various products on the market that claim to kill, suppress or eliminate Ich. Until then, I will personally quarantine all new fish/inverts and treat any fish with Ich in a hospital tank with either hyposalinity or copper.
