I agree, try something else to treat them other than giving them away to someone else to deal with. Disease and keeping your fish healthy are part of the hobby. Nothing will cure them instantly other than a good treatment and quiet time for the fish. I always had great success with Kent's Garlic Extreme. If I were you, I would also try to figure out what is causing the ich. Most of the time it is some kind of stress from their surroundings or water conditions. If you get new fish and do the same things or put them in the exact same environment they will most likely get ich as well.
