API Melafix All-Natural Antibacterial

API Melafix All-Natural Antibacterial is used to treat bacterial infections in fish, such as open wounds, tail rot, eye cloud, and mouth fungus, while promoting regrowth of damaged fins and tissue.

API® MELAFIX fish remedy is an all-natural antibacterial treatment that works to treat infections in fish. Common bacterial infections are open wounds and abrasions, tail rot, eye cloud, and mouth fungus. MELAFIX fish remedy also promotes regrowth of damaged fins and tissue. Product may be used when adding fish to an aquarium – particularly to smooth the transition from store to home – and if an infection is suspected, but not yet diagnosed. Some fish bought in pet stores are already carrying diseases at the time of purchase, which may be difficult to detect in its early stages. API MELAFIX fish remedy will not adversely affect the biological filter, alter the pH, or discolor water.

Instructions
Add 5 ml. for each 10 gallons of aquarium water. For disease or wound treatment, dose daily for 7 days. After 7 days, make a 25% water change. Continue treatment, if necessary. For adding new fish, dose daily for 3 days.

Dosing
Add 5 ml. per 10 gallons

FAQ

Is API MELAFIX™ fish remedy recommended for freshwater tanks?
API MELAFIX fish remedy 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 fish remedy.

How do I diagnose disease in my fish?
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 fish remedies, which include treatments specific to Ich disease, Betta fish, and various common symptoms (hole-in-the-head, eye cloud, fin & tail rot, etc.).

Does API MELAFIX™ fish remedy work for fin rot and Ich if my fish is fighting both?
API MELAFIX fish remedy heals bacterial infections such as fin & tail rot, eye cloud, popeye, body slime, and mouth fungus. As a general note, all API fish remedies 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 fish remedies at a time unless you are certain of the diagnosis of multiple ailments, so that you can tell which fish remedies are working or not working while troubleshooting a stubborn symptom or disease.

After treating my aquarium for several days with MELAFIX™ fish remedy, my water turned very foamy, and hasn’t gotten any less foamy over the past three days. Is this normal?

Yes, it is normal to see some foaming when using API MELAFIX fish remedy, 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™ filtration media in order to eliminate any remaining fish remedy. 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 fish remedy residues until they clear from the system.

What does API MELAFIX™ fish remedy do?
API MELAFIX fish remedy is a treatment for external bacterial infections in fish, such as fin rot or open wounds.

Is API MELAFIX™ fish remedy safe with invertebrates such as snails and shrimps? Will it harm the biological filter or aquarium plants?

API MELAFIX fish remedy is completely safe with invertebrates such as snails and shrimps, and will not harm the biological filter or aquarium plants.

Can I use API MELAFIX™ fish remedy and API PIMAFIX™ fish remedy together?

Yes, this combination is in fact recommended if treating stubborn infections. Use each fish remedy at the recommended dose. There is no need to reduce the dose when using both of them.

Can I use API MELAFIX™ fish remedy with any other API fish remedies or products?

API MELAFIX fish remedy can be used safely with all other API fish remedies and products.

Transformative for Dry, Cracked Heels!
Color: Original Grey
I recently purchased Dr. Frederick's Original Moisturizing Heel Socks, and they have truly transformed the condition of my feet! I can’t recommend them highly enough. Effective Moisturization: These socks are infused with moisturizing agents that work wonders. After just a few uses, I noticed a significant reduction in dryness and cracking on my heels. My feet feel softer and smoother, and I love that I can wake up to beautifully moisturized skin. Comfortable Fit: The socks are incredibly comfortable to wear, with a snug yet gentle fit. I appreciate that they don’t feel restrictive, allowing me to walk around my home while wearing them without any discomfort. They are also lightweight, making them easy to slip on before bed. User-Friendly: They are super easy to use—just wear them overnight, and let the socks do their magic. I love the simplicity of incorporating them into my nighttime routine. Durable Quality: The quality of the socks is impressive. They wash well and have maintained their shape and effectiveness after multiple uses. I feel confident that they will last a long time. Final Thoughts: If you're struggling with dry, cracked heels, I highly recommend Dr. Frederick's Original Moisturizing Heel Socks. They are a fantastic investment in foot care and have made a noticeable difference in the health of my skin. These socks have become a must-have in my self-care routine!

These worked for me!
Color: Original Grey
They worked great. I bought these for cracked sore heels. It took 2-3 weeks but my heels no longer hurt and the cracks have closed and look more like an indention than a crack now. They feel so much better, but I'll probably wear them another week just to be sure they stay healed. They look and feel like regular socks from the outside but only cover the heel with the toe open. Not think but not thick, again like regular socks. They would probably be slippery on a smooth surface the same as socks. The inside feels like rubber or something smooth at the heel. I have washed them once each pair and accidentally dried one pair in the dryer. They still seem to feel the same so I think they're fine. They're pretty inexpensive and had different colors and sizes.

Truly Helped My Cracked Heels
Color: Original Grey
I didn't include a photo cause they look exactly like their advertisement photo. I so liked the silicon-type heel lining as it kept the heel-repair cream on my heel and did not get soaked up by the sock. But, it is so, so slippery when walking around in them! Take care to be mindful when you set each foot down as the lotion can slide your heel across the sock quite a bit. If these socks were for an elderly person, I would have them only sit while using the sock - no walking around for fear of falling. I have larger ankles and found that having both the top and the bottom hems/elastic, etc. the same size to be quite troublesome and was not a nice feeling or fit on my upper hem that hit my ankle. Don't get me wrong, I am so glad that I got them and I continue to use them and they are helping my horribly-cracked heels greatly, but I find that I have to keep moving the top hem up and down so that it doesn't stay in one position as it cuts in to my ankle. My feedback and advice might be to please make the upper hem somewhat larger than the one that is on the bottom and goes over my actual foot. They really should not be the same circumference...or else make different sizes - S, M, L, etc. That's really my only complaint or "con" to ordering these. I think they are a great concept and I like the fact that I can throw them in the washer and dryer.
