Well, that's is pretty lucky for you, Fishkiller. The water changes were more likely what did the trick, not the bottled garlic. Have you done routine checks of your fish with a mag. glass? Sometimes ich can stay in check on healthy fish (but the fish still will harbor a few parasites at a time that go unnoticed). If I see that the water change out method is at least moderately reliable, I could start to suggest that here more often (particularly with hobbyists who have reef tanks).
