How to Use Kusuri Formalin and Malachite Premix
Switch off UV steriliser until course of treatment is complete. Tighten cap and mix well. Use cup supplied to measure the correct dose. Add water to a clean watering can, then add Formalin/Malachite Premix. Gradually sprinkle across the surface area of the pond over a 1 hour period. Do not use below 12.5°C.
Do not use Malachite and Formalin Premix in conjunction with salt.
Stop feeding during the course of treatment because Malachite and Formalin will reduce the bacteria in the filter, continuing to feed will cause an ammonia spike.
Once the course of treatment is complete monitor your water parameters regularly and add good bacteria to restart your filters, such as the Kusuri Filter Starter Booster
