Kusuri Formalin and Malachite Premix

Sale price£30.00

Kusuri Formalin and Malachite Premix is a ready to use full strength formulation, popular as a pond-wide anti-parasite treatment. It is particularly good for white spot, skin flukes, chilodonella, oodinium and most protozoan parasites.


10ml per 100 gallons of pond water.


Treat up to 3 times 5-7 days apart maximum.

Slowly apply to the pond over a 1 hour period, this will prevent shocking the pond with a highly concentrated dose.

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.

Do not use below 12.5°C.
