The best way to go, in my books, is the heat and salt method. I have used this every time I've had an outbreak and it ALWAYS works. I found with meds that it's harder on the fish, sometimes you have to do more than one round and it can be expensive. Salt is much easier and natural. I always use about one handful per 5 gal of water and have never had to re-treat after it's gone. The salt then slowly goes down with water changes after the ich outbreak is over and salt is always helpful when your fish are stressed or under the weather. :thumb: (just make sure that any water changes during the treatment are followed by "topping up the salt")
