NT Labs Koi Care – FMG Mixture


NT Labs Koi Care FMG Mixture is an anti-parasite and fungus treatment that is a mixture of Malachite Green and Formalin. FMG provides the same treatment levels as the two individual components used separately.

A ready mixed Koi treatment eliminating the need to mix separate treatments, the treatment levels are higher than other proprietary mixtures which means this product should not be used when sensitive fish such as Golden Orfe or Sturgeon are present. FMG can be used where Goldfish are present.

Use this when fish show symptoms of a parasitic or fungal infection, including white spots along the fins and body, flicking and rubbing, gasping at the surface, an opaque film over the body or fluffy, white growths.

Available Sizes:

250ml - treats 9000 litres (2000 gallons)

500ml - treats 18,000 litres (4000 gallons)

1 litre - treats 36,000 litres (8000 gallons)
