## Overview

Kusuri Fluke M 65g is a potent 50mg/g Flubendazole dry powder treatment designed to eradicate gill and body flukes in cold and tropical freshwater fish.

## Description

Product Description Kusuri Fluke-M is a 50mg/g Flubendazole based medication used to eradicate Gill and Body Flukes. This treatment is safe to use without destroying the bacteria in the filter and can be used at any temperature. While dosing with Fluke M you can continue to feed. If the mucus layer is excessive, we advise dosing with Chloramine T at 15g per 1000 gallons, 12 hours before using Fluke M, this will assist in reducing the mucus membrane where body flukes can sometimes get trapped. Kusuri Fluke-M is not an invasive, toxic medication like Kusuri Malachite Green and Kusuri Formalin 30%. The Flubendazole is absorbed by the flukes and dissolves their digestive tract that subsequently starves the parasite. Fluke M may require a second dose after 7 days in heavy infestations. Kusuri recommend a mucus scrape and microscope identification prior to a second application. For use with all cold water ornamental fish and can be used safely with all tropical freshwater fish. Kusuri Fluke-M has a four year shelf life from date of manufacture and should be used within three months of opening. Fluke-M can also be used for the eradication of pond snails and Intestinal Helminths Worms. For best results use above 15°C. At 10°C a second dose may be required. Please ensure that you read, understand and follow, all Health and Safety guidelines on the packet. Indications Gill and Body Flukes Ingredients Flubendazole Directions Dosage: 11.8g per 1000 gallons (4546 Litres) of pond water. For best results use above 15°C. Kusuri Fluke M stays active in the water for a total of 7 days. Shake contents of the sachet well. Measure out the correct dose for pond and dissolve in a container with boiling water. Stir and allow the mixture to cool before adding slowly to the return of the pond over a 1 hour period. It is recommended that you turn off the UV. Fluke M is safe to use with salt. This product is designed as a one off treatment, but may require a second dose after 7 days in heavy infestation. Alternatively you can use Kusuri Fluke P or Kusuri Fluke S after 7 days. Box Contains Contains: 1 x Kusuri Fluke-M 65g

Review: Recommended - Excellent, non-aggressive medication that removes a range of parasites without damaging the bio component of your filter. Certainly should be considered a first port of call before resorting to potassium permanganate.
Review: It took 3 doses but worked - My fish were really sick and not improved after 5 days. I spoke to Kusuri the guy was good I did a skin scrape to be sure and yes it was flukes. He said it was warm and I may need to do 3 applications and about 4 days after the 2nd one they were better but not fully recovered so I did the third. They have a good technical department you can call I would buy their stuff again
