Kusuri Formalin and Malachite Premix is an anti-parasite treatment which is ready to use. This special formula is a popular choice with pond keepers that is especially effective for treating white spot, skin flukes, chilodonella, oodinium and most protozoan parasites that can afflict your fish stock.
Directions: Administer in a dosage of 100ml per 4546 litres of pond water. Treat up to three times 5-7 days apart and only when water temperatures are above 12.5 °C. Slowly apply to the pond over a period of 1 hour as this will prevent the dose being too concentrated. Do not use this formula in conjunction with salt. Do not feed your fish during the course of treatment with Kusuri Formalin and Malachite Premix. This formula reduces the bacteria in the pond filter and so feeding will cause a spike in ammonia. When the course of treatment is complete continue to monitor your water's parameters and add good bacteria to your pond to kick-start the filters. You can use Kusuri Filter Starter Boost or Kusuri Starter Pink to do this.
