    Overdosing - NT Labs Anti-Parasite & Fungus

    Hi All,

    Need some urgent advice.

    I've misunderstood the instructions on how to use Anti-Parasite & Fungus (https://www.nt-labs.com/browse-produ...ponds/eradick/).

    Instead of adding a enough for a 6,000 litre pond for one day, I've added 5 doses in one go!!!

    So I'm stressed out what the best plan of action should be now?

    I've been monitoring the Koi and they are moving around a bit slower than normal.

    I've never used any of these products before, so I don't know what to expect.

    Thanks,

    Mohs

    If you are sure that you've massively overdosed, then the best course of action would be to dilute with a water change, ensuring that the fresh water is free from chlorine/chloramine etc.

    Also perhaps contact NT Labs for advice.

    Yes, I agree with that.

    Fortunately, that treatment is only Formalin and Malachite Green which is well diluted so, if the fish aren't behaving as if they're suffering, I'd suggest an immediate 20% water change by draining and refilling with a hose (and dechlorinator) because refilling with a hose is the quickest way to top up and dilute the treatment. Follow that with 10% daily changes for a week.

    If the fish look as if they are suffering badly, I'd do at least a 50% change because, although such a change isn't normally advisable, it would remove the risk of them dying while waiting for a slower rate of changes.

    Let us know how you get on.

    Thanks - I did a water change last night as a precaution, about 30%ish. All the fish seem active this morning and no losses. Iíll probably lay off feeding them until tomorrow.

    Iíll keep you updated.

    Whilst on this topic, my setup is filter to a Bakki Shower with BHM, I heard these treatments recommend avoiding the use of Carbon filters. So Iím guessing for the next 10 days it will be better to bypass the Bakki?

    The reason to bypass carbon filters when treating a pond is to prevent them filtering out the treatment. A Bakki Shower won't filter out treatments so I would leave it on.

    Was going to suggest water changes when I saw the title of this thread.

    Well, if OP's Koi have survived all well and good after a 5x overdose, I highly suspect any parasites would easily survive at the correct dosage!

    OP is fortunate that the mistake was made using a product that appears to have a concentration of active ingredients weak enough to allow for this kind of error.


    I'd be interested to know what exactly the treatment was for?

    Looking at the Manufacturers website the breakdown is:

    Malachite Green 500 mg/100ml, Formaldehyde 4890 mg/100ml

    I think for Formaldehyde that means about 5%, which is pretty weak as Iíve seen 30% which is 30000mg/100ml.

    I essentially gave them a shot of 25%

    So I think I overreacted, when I look at the data.

    The worse thing is a did about 50% water change (3000 litres) and my house is on water meter!!!

    And the Malachite is half the concentration of other brands such as Kusuri.

    As for your water meter costs..... it could be worse, just for general maintenance I'm averaging 1500 litres a week and on a meter, often get through more in the height of summer as daily top-ups alone often hit 150 litres on top of the weekly 10% water change.
