Anti-Parasite and Fungus Mixture of Malachite Green and Formalin formulated for treating sick Koi with a parasite or fungus infection.

• Ready-mixed Formalin & Malachite

• Powerful single shot dose

• Easy to use

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. 



This is the market-leading anti-parasite and fungus treatment for Koi. There is nothing else on the market as effective as FMG to fight unwanted parasites... A Koi keeper's secret weapon!


Directions: Use when fish show symptoms of parasitic or fungal infection. Switch off UV until all the colour has gone from the water. Test your water quality first using Pondlab test kits. Aerate your pond well during medication. Wait 7 days before treating with a different medication. If you feel that a repeat dose is necessary, check your diagnosis carefully using the diagnosis tool on our website, a different medication may be more suitable. Always treat when you have time to observe fish and take appropriate action if they react badly. Do not use with Orfe, Rudd, Tench or Sterlet/Sturgeon. Do not use at water temperatures above 30oC or in hot, humid, thundery weather. Do not mix medications. Can be used in Ponds with low level salt ( 1 to 1.5 oz / gallon salt ) with no detrimental side effects.

Dosage: 250 ml treats 9000 litres (2000 gallons)
