No! Don't use garlic. Have you read Steven Pro's article on Garlic? Garlic has never been proven to cure ich and cause more problems when fixes them. I learned my lesson because my kole tang after given garlic was starting to have skin erosion. The only 100% effective way to cure ich is to qt all new fish into the main tank! Everyone who has a tank should have a qt tank.
