FAQ
API MELAFIX will treat your fish’s symptoms in freshwater and saltwater aquariums. If you are treating fish in a marine or saltwater aquarium, dose with API MARINE MELAFIX.
Many disease symptoms will be clearly visible, such as white streaks, lesions, protruding eyes, and other unusual marks or spots on your fish. If you suspect your fish has a disease, it will fall under the categories of fungal, parasitic, or bacterial. One way to diagnose is by matching fish symptoms to the description of a wide range of API medications, which include treatments specific to Ich disease, Betta fish, and various common symptoms (hole-in-the-head, eye cloud, fin & tail rot, etc.)
API MELAFIX is safe for delicate fish species, all marine fish, and reef aquariums, while Bettafix is specifically formulated for Betta fish.
API MELAFIX heals bacterial infections such as fin & tail rot, eye cloud, popeye, body slime, and mouth fungus. As a general note, all API medications can be used in conjunction with each other safely, as long as you are able to follow the directions for both during treatment. We would not recommend using more than two medications at a time unless you are certain of the diagnosis of multiple ailments, so that you can tell which medications are working or not working while troubleshooting a stubborn symptom or disease.
It is normal to see some foaming when using API MELAFIX, and it is not harmful as long as the proper doses were given. In terms of duration, the foaming of this product can last a variable amount of time depending on what is dissolved in the water. Water that contains a lot of dissolved organics or proteins can experience more foaming that lasts for long periods of time, but in general, if foaming lasts more than a week after discontinuing the treatment, we would recommend more frequent water changes and the addition of Activated Carbon or Bio-Chem Zorb in order to eliminate any remaining medication. Make sure that skimmers are turned off during treatment, as this would contribute to excessive foaming. It may be prudent to turn the skimmer pump flow down when it is restarted after treatment, to account for medication residues until they clear from the system.

I bought this for my two gigantic comet goldfish. One has cloudy eyes and can’t see its food. The other some skin irritations. I’ve been using this for 2 weeks and no sign that it’s working.I’ve tried many medications and thought, by reviews, that this would be the cure all. I’m not very optimistic that it will do the trick.

One of my large Koi developed two red "bruises" one on each side of its body. First round of treatment completely cleared one of the red bruises and lessened the size of the other. However the remaining "bruise" has a small scrape in it. I began a 2nd round of treatment and the healing is nearly complete. So happy with this product and the price on chewy.com - it's saved my expensive Koi as well as my bank account!
