FMG Mixture from NT Labs. A mixture of Malachite green and Formaldehyde are the best combination to treat common external parasitic infections or Koi fungus infections.

This combined treatment cuts out the need for separate medications, just one dose for five days builds up the level of treatment for best effect. It kills all swimming and developing ectoparasites, reducing the risk of infection in Koi and other pond fish.

Due to the strength of the treatment it only needs to be applied once. However this means it is dangerous to use in ponds containing sensitive fish such as Sterlet, Tench, Rudd or Orfe.

For these species use NT Labs Anti-Parasite and Fungus, which is a weaker treatment, and must be applied on alternate days for 5 days.

  • 10ml Treats 364ltr
  • Switch off UV untill all the colour of the treatment has gone from your pond.
