there is no proof that garlic prevents ich. it is more of a "he said-she said" type of thing. worth a shot though, and does provide vitamins.
it doesnt as i stated in my extremely long paragraph that no one probably read....it only boosts immune systems of the fish like garlic does in humans.
the commercial UV are no good thats true but there are other ones like the one i use that offer triple exposure to uv radiation and effectively kill the protozoans and other parasites.
but a natural method is always a good choice. u can always try one if the other fails.
