Kusuri Fluke M

Targeted pond fish treatment for controlled, label-led use

Kusuri Fluke M is a powerful 50mg/g Flubendazole-based pond treatment designed to eradicate gill flukes and body flukes in koi and ornamental fish. It works by being absorbed into the parasite, disrupting its digestive system and causing starvation. It is safe for fish when used correctly and does not harm biological filter bacteria, making it a reliable treatment for parasite infestations.

Fluke M can also be used for internal worms and certain external parasites when required.

Kusuri fish health treatments should be used as part of a controlled diagnosis process rather than as a casual pond additive. Before using Kusuri Fluke M, check ammonia, nitrite, pH and KH, observe the fish closely, remove as much uncertainty as possible and calculate the true pond volume. Many fish health problems are made worse by poor water quality, low oxygen or incorrect dosing, so the product label and manufacturer instructions should always come before general website guidance.

Kusuri medicine guidance emphasises accurate pond volume calculation, premixing treatments in pond water and maintaining strong aeration during medication. Their FAQ gives exact treatment intervals and dosage for several key medicines, so the manufacturer label should always be treated as the authority.

Diagnosis and treatment guidance

Use Kusuri Fluke M only when the symptoms, fish behaviour and water test results support the treatment choice. If fish are flashing, clamped, lethargic, gasping or showing visible sores, first check water quality and oxygen levels because ammonia, nitrite or pH instability can cause similar signs. Where a parasite or infection is suspected, scrape and microscope confirmation is always preferable before treating valuable koi.

How to use safely

The product label should always take priority over general guidance. The points below are included to help customers use Kusuri Fluke M in a more careful and informed way.

Test ammonia, nitrite, pH and KH before treating; poor water quality can mimic disease symptoms.
Calculate pond volume carefully, allowing for shelves and irregular shapes.
Increase aeration before and during treatment because many medicines reduce oxygen levels.
Do not mix medications or overlap treatments unless the manufacturer specifically confirms it is safe.
Remove carbon, zeolite or purifier media if the label instructs you to do so.
Observe fish during treatment and stop if they show severe distress.
Follow the label for repeat doses, treatment gaps and water change guidance.
