    NT Labs Malachite 250ml

    Anti-Fungal Treatment for Koi  

    Treats: Fungus caused by Saprolegnia

    When to use:

    • When fish have white growths on the body, head or fins, which may contain some green or brown discolouration.
    • Malachite can be used in conjunction with Koi Care Formaldehyde to treat fungal infections more effectively.
    • Suitable for koi only.


    • Test your water quality using Pondlab Test Kits.
    • Mix the appropriate dosage in a clean bucket of pond water, pour evenly over the surface of the pond and leave for 7 days. Switch off UV filtration until treatment has been completed. Aerate the pond well during treatment.
    • If you feel a repeat dose is necessary, check your diagnosis carefully using the Diagnosis Tool on our website; a different medication may be more suitable. Allow 7 days and perform a partial water change before re-treating or treating with a different medication.
    • Always treat when you have time to observe fish and take appropriate action in the unlikely event of a bad reaction.
    • If required, mix with Koi Care Formaldehyde prior to adding to the pond, following the instructions above.


    • Do not use with orfe, rudd, tench or sturgeon/sterlet.
    • Do not use if the water temperature is above 30°C.
    • Do not use in hot, humid, thundery conditions.
    • Do not mix medications, other than combining with Koi Care Formaldehyde.
