## 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 over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your fish and aquarium. API Aquarium Treatment Supplies are designed to work in conjunction with each other to provide best results to control algae, promote healthy bacterial growth and help control and cure fish diseases and conditions such as ich and fin rot. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. With API, you can spend more time admiring your fish, and less time scrubbing your tank. Make sure to use all products as directed in order to ensure the best results.

Review: I did notice that he loved to puck on corners and squeeze behind the sponge ... - This product really worked as described! I am a newbie fish owner, so I have very little experience taking care of my goldfish. However, I noticed that he had some scales fallen out after having him for less than 1 month. I didn't know how he had a few of his scales fallen out since he was in a 30 gallon tank. I have few ornaments in the tank, and there weren't any sharp objects as well. I did notice that he loved to puck on corners and squeeze behind the sponge a lot, so I assumed it may have been from that. So, I went online and started reading up on how to take care of my goldfish and how to help him grow back his scales or prevent more from falling. At this time, I also wasn't sure if he had other diseases as well since this was my first time taking care of a fish. So, I saw and read several reviews on this product where previous customers and experienced fish owners wrote about it helping their fish, as well as, preventing diseases and other ailments. I thought I gave this item a try. It was one of the best products I've bought for my fish. It really helped him healed his scales. I noticed the area where his scales were missing darkened and turned fleshy again. In about 1 week or so, I noticed the area started growing scales already. I am very happy with this item. However, this product is very strong. I have a small, young goldfish in a 30 gallon freshwater tank, with a 50 gallon Aquaclear water filter system, and following the dosages for this product for a 30 gallon tank, I noticed my goldfish acted very agitated to this product. His eyes also started bulging out more. After observing this, I did 25% water change and used half the given dosage. I think this amount was more tolerable to my baby goldfish. I also noticed that my fish scales and fins became silkier after a week of usage. I'm really happy I tried this product out. I would recommend a lower dosage if you have smaller fish. I also recommend to do at least 2 days 25% water change every time you use the product.
Review: Saved my Black Moor Goldfish! - My black moor goldfish accidentally got stuck in the siphon when my son was cleaning the tank and it damaged his eye. I put him in a nursing tank and added the Melafix and within 4 days his eye was completely healed. Amazing product!! The water did turn cloudy and murky with the medicine in it but I just monitored the water with test strips and as long as it was good then I continued the treatment.

## Questions & Answers

**Q: could you use this when quarantining fish?**
A: API suggests to use Melafix AND Pimafix together for Flukes and Parasitic Worms OR use General Cure for 7 days - what ever you treat with also add heat to 85-86 degrees to kill ICH along with Flukes and Parasites. That covers them all :) That’s what I do BUT YOU MUST add a few air stones because heat and meds take up a lot of oxygen. The air stones will keep the oxygen in and circulate the water. use a few Gallons in a container or tank and change the full water everyday to match the temp, redose just the right amount for the same water you change. Changing the full water daily gets rid of dead parasites, bacteria and fungus. I have used both ways but like General Cure and heat for QT better. If after General Cure treatment and the fish still have some sort of fungus or bacteria skin problem.... then QT 7days again with just Melafix and Pimafix so they can heal completely before putting them in display tank. Also when ready to move the QT fish(s) to Display tank... raise the heat in your display tank to 85-86 for a week just to be safe ALL fish in the tank are clear of ICK so no one will have an outbreak from stress while the new fish is adjusting. This works 100% of the time for me and everyone stays healthily while adjusting.

**Q: Why the bootle of 8oz said melaleuca 1%  and when i select the bootle of 16oz said pimenta ..why??**
A: pimenta is stronger. they probably assume you have a big tank and big fish, but it works well with smaller fish

**Q: How does this affect the chemistry of the water? Does it increase Nitirite? Thank you.**
A: It shouldn't affect your water chemistry at all.

**Q: can i use this with ich-x????**
A: No, it will kill your fish. Don't use this product at all. It is basically melaluca oil and it will clog your fish's gills and they suffocate to a slow death. This should not be sold as a fish remedy, but as a fish euthanizer. API should be ashamed of themselves. My poor goldfish. :(

### ⭐⭐⭐⭐⭐ This Really works!
*by P***E on November 3, 2014*

Have you ever witnessed the ping-pong ball drop into the fish bowl and your son or daughters eyes light up like vegas slot machine? 3 years ago those lights were beaming from my kids eyes as mine were rolling back. "Mr. Bubbles we'll call him Dad" as I smiled through gritting teeth while thoughts of accidentally dropping the bowl in the parking lot danced in my head. While on the ride home I was reminiscing on all of the bad luck pets have had under our care and came up with a brilliant idea to tell my kid. "Honey, I know you love Mr Bubbles, but just know that these little fish only live a couple weeks" (I was hoping I could keep it alive at least that long) Three years and $200 later after 2 tank upgrades, pumps, filters, gravel, plants, log and all of the water conditioning chemicals Mr. Bubbles has survived. (After 3 months my kid changed the name to Miracle as it had far surpassed the life span I had given it. ) About a month ago, Miracle was hanging out on the bottom of the tank, not moving to much. After a few days of him being lethargic, we noticed some white gunk on his gills and his fins were not looking good. I googled and thought I found the answer in "Ick" after that did not work and Miracle's condition worsened, I researched some more and found fin rot as the culprit. By this time, Miracle was just laying on the bottom of the tank mostly on his side, eyes clouded over…. not good. Day one after putting the Melafix in the tank, he started swimming again, By day two he looked to be swimming even better, within a week, He is like a new fish again! No more cloudy eyes, strong swimming and appetite is back. This stuff really works! Highly recommend it!
