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 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.

  • Great Product & Company
I have used this before and it really helps the fish repair their skin. We used it in the Golden Dojo Loaches aquarium, which have sensitive skin, not scale like. It is easy to use with good instructions. This was a replacement order since the first one came in a damaged box with a damaged lid and leaking product. The replacement came 2 days later and they used a packaging material to keep it from moving around. It was still in an amazon box too small so it was diagonal but there wasn’t any damage so, no complaints. ... show more

  • Excellent product
We always use this product whenever we have a sick fish in our tank. Within a couple of days, the fish are usually better.

  • My fish seem calmer
I have a couple of goldfish with broken tails and fins. I've been using this product for about a month, and I've already noticed new growth. It does make the water a little foamy at first, but this goes away after a couple of cycles through the filter.

  • Not good for Snails!!
I bought this to cure red spots on my fish. I followed the instructions as directed, and the red spots are now completely gone. Unfortunately, however, all of my snails died :(
