Not to rain on your parade, but i currently have ich in my tank, i fed garlic for 2 weeks almost, and symptoms got worse, tonight i set up my 30 gallon for qt tank. Believe me i did not want to do this,because i tore my tank down all the way to catch my fish, (200-250lbs.) it sucked, so on that note. good luck.. maybe you will be one of the lucky ones.....
