Kusuri Formalin
Kusuri Formalin is used normally, with Kusuri Malachite green, and this aids the eradication of White Spot, it strips off some to the protective mucus layer on the fish thus allowing the Malachite Green to work. Kusuri Malachite green and Kusuri Formalin are the best treatment for common external parasitic infections. We do not recommend the use of Kusuri Formalin with any salt in solution. Kusuri Formalin is for use above 12.5c. One more thing, please make sure you have plenty of Oxygen in your pond when using Kusuri Formalin and Kusuri Malachite.

Gradually sprinkle across the surface area of the pond over a 1 hour period. Do not use below 12.5°C. Never use KUSURI Formalin with salt in the pond, or if the liquid has gone cloudy, or has crystallised.
Stop feeding during the course of treatment because KUSURI Formalin will reduce the bacteria in the filter, continuing to feed will cause an ammonia spike.
