API Furan-2 Freshwater Aquarium Fish Medication
Oops! Something went wrong. Please try again.
Quickly and effectively treat a wide variety of bacterial diseases with API Furan-2 Powder for Bacterial Disease for Fish. Most bacterial diseases are caused by dirty aquarium conditions, but there are smaller groups of bacteria that can infect fish in otherwise good aquarium conditions. And they can be difficult to diagnose. Symptoms, like listlessness, weakened or abnormal swimming, dark blotches and loss of appetite, are similar across the spectrum. Left untreated, they can cause damage to internal organs and even death. API Furan-2 Powder for Bacterial Disease for Fish treats a broad spectrum of bacterial diseases, usually in 48 hours. It contains two furan compounds, effective antimicrobials that combat gill disease, mouth fungus, furunculosis, black molly disease, fin and tail rot and dropsy. Simply remove the carbon or filter cartridge and add manufacturer's recommended amount directly to the water.

For best results, remove activated carbon or filter cartridge from filter and continue aerations. For each 10 gallons (38 L) of water, empty one packet directly into aquarium. Repeat dose after 24 hours. Wait another 24 hours then change 25.0% of the aquarium water. Repeat this treatment for a second time, for a total of 4 doses. Then make a final 25.0% water change and add fresh activated carbon or replace filter cartridge. Treatment may be repeated if necessary.
When should I use API FURAN-2?
Use API FURAN-2 when you suspect your fish is sick with a bacterial infection, symptoms of which include weakened or abnormal swimming, dark blotches on the body, and loss of appetite. If these symptoms are left untreated, they can cause damage to internal organs and even result in fish loss, so it is important to act quickly if you believe your fish is infected. Dose accordingly with API FURAN-2 for highly effective results.
Can API FURAN-2 be used/combined with other treatments for faster results?
API FURAN-2 works quickly and effectively on its own; however, some great products to use in combination with it are API AQUARIUM SALT and API STRESS COAT, both of which promote healing and boost fish immune systems. If your fish appears to be suffering from more than a simple bacterial infection, you may use another medication in conjunction with it 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 disease issue.
Should I remove my filtration media before dosing with API FURAN-2?
Products that are designed to remove things from your aquarium, such as filter media, will also remove dosed medication from your tank. For best results from medication, remove your filtration media as you dose.

By britbabe on Apr 16, 2021
This stuff works well - You have to use two boxes to be effective according to the box- but it killed whatever was growing on my fish.

Product quality
By Linda on Jul 24, 2020
I haven’t used this product yet. I used the product for General Cure first, and that product didn’t seem to work for what my fish is ailing with. I am about to use this product to see if it will work.

Good when natural remedies didn't help
By Emily on Dec 10, 2017
I was recommended these through API after trying melafix and pimafix and still having red spots on my fishes gills. It took about 2 to 3 days to notice a difference but my gosh look happy and healthy again and are more active. The down side is it will turn your water a yellowish green color but once you add the filter cartridge back in it takes it right out. Differently recommend for sick fish when natural remedies don't help as fast.
