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, such as  Kusuri Filter Starter Boost  or  Kusuri Starter Pink.
