Just to throw my 2 cents in. I’ve used API’s super ich cure for years and have lost almost no fish with it. Ich-X I tried a few times at the advice of the guys at Aquarium Co-op, but I just didn’t see the results I was looking for, and typically still had sick fish after the recommended dosage. One run of the API stuff and it was gone. Of course, as I got deeper into the hobby and finally set up a quarantine tank the need for a lot of this stuff went away, but not everyone has the room to do that and if you’re only keeping one tank and only buying fish every few months it’s a waste.

I also like Melafix a lot as well. A lot of people online will tell you that it doesn’t do anything, but I’ve used it almost like a Neosporin for fish with damaged fins and had great success.
