## Overview

API MELAFIX is a 64-ounce natural antibacterial remedy formulated with botanical tea tree extract to treat bacterial infections, heal damaged fins, ulcers, and open wounds in freshwater fish.

## Description

API MELAFIX Freshwater Fish Bacterial Infection Remedy soothes the transition from store to home by reducing the risk of your fish developing a disease. The fish you bought may already carry a disease. Disease is often difficult to detect, particularly in its early stages. Treat bacterial infections in your fish and reduce the risk of spreading illness to other fish with API MELAFIX Freshwater Fish Bacterial Infection Remedy. Bacterial diseases are caused mostly by dirty aquarium conditions and the addition of infected fish. Fish that are injured and have open wounds are especially susceptible, even in seemingly clean tanks. Bacterial infections, like fin and tail rot, eye cloud, pop eye, body slime and mouth fungus destroy tissue and other organs, and if left untreated, can cause death. API MELAFIX Freshwater Fish Bacterial Infection Remedy is an all-natural antibacterial treatment that heals open wounds, treats bacterial infections and promotes re-growth of damaged fins and tissue, usually within a week. Just add 5 ml per 10 gallons of aquarium water. It will not adversely affect the biological filter, alter the pH or discolor the water. For effective treatment, dose infected fish daily for 7 days, and continue afterward if necessary. Dose new fish daily for 3 days. Remove activated carbon from filter before use, if possible. With API aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For almost 60 years API has developed premium solutions with proven and effective results for your family and ours. API offers a range of testing kits, water conditioners, and nutritionally superior food, because we’re dedicated to making a better underwater world. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. At API, we understand the rewards and relaxation of fishkeeping because we have a passion for fish too.

Review: Good value, plant safe. - The large size is a better value. This product is a good fish safe, I believe it is nontoxic, and works well in a planted aquarium.
Review: Smell is fine, kind of refreshing plus I new it was ... - This and Pimafix, combined with Medi Koi food at the end, saved my koi. I had fin rot on almost 50 fish, stressed out by unusually hot weather this spring. I never had issues with diseases all these years. My pond is dialed in. But thist came on quick and sudden. I have a 16,000 gal pond, so netting the fish is not an option. I used 64 oz of Melafix and 128oz of Pimafix every 3 or 4 days for a total of 4 treatments each. Water foamed slightly with waterfall and aerator but nothing major. Smell is fine, kind of refreshing plus I new it was there and working. I was able to catch a very sick, 16" fish. I treated him in a small 30 gallon holding tank for 10 minutes following the instructions on the bottle. He was near death but came back out of it and looks good today. I made sure to keep a gallon each on hand and I may add this to the pond every spring now that I'm paranoid.

## Questions & Answers

**Q: This site list melafix from two different venders, mars and pond care. big difference in priceing. are they the same?**
A: I've used several different brand types of melafix and found that they work just the same.

**Q: Is it safe to use post-expiration? In other words does it turn toxic to fish or simply starts to lose the effectiveness?**
A: I would think if this is not very much over date, like 6months or so, it would be fine. If it is still sealed, it will be like new or almost. If it is older, it probably, hate to say as this, but I would think it will be okay to use, and just be weaker or maybe not. If you are in doubt, I would buy a new one to be certain. In the past, they never put dates on anything, and now a days they do and the things were used and were okay. Best answers I can give you. Good luck with your issues.

**Q: I guess my butterfly goldfish has fin rot. How should I treat it? It is in a pond with other healthy fish.**
A: If the other fish are healthy. Then you should remove it in to a isolation tank. Be sure to use the pond water when you fill it. There are instructional videos on YouTube that will show you how.

**Q: How is this different from regular strength? They both have 5% concentration in a 64 oz bottle.**
A: My advice is to please ask a professional breeder for direction. Off the self purchases is "gambling" to me!
Best wishes to you and the Fish :)

### ⭐⭐⭐⭐⭐ Great medicne for all kinds of fish
*by M***Y on March 3, 2017*

This medicine really helps get rid of and even prevent ich for me. I have a goldfish tank and getting new ones can be hard because it's not uncommon for them to already have ich or have been exposed to it while in the store. Treating with this when adding new fish can help stop an out brake. Recently I have had both my freshwater and my goldfish tank get ich from new fish after a doing a full daily treatment for 2-3 days I noticed the ich reduced if not disappear all together, then I do a small water change and treat with a little lower dose for several more days. You do have to be careful not to overdose as this can cause fish to die by putting the tank to much out of balance or just from plain over medicating them. It's also not a bad idea to add a little stress coat when treating for ich as ich causes damage to the fish's protective coating. This medicine also helps heal torn and tatered fins and tails.
