    In my top pond PP every year after winter.
    No fish in there just plants. Lilly's. Iris. Dutch rushes. And another plant. Don t know name. But they are always ok after a 24 hour soak in PP

    There will be a higher organic content because of the plants, that will neutralise the PP quicker.

    If you put enough in. Your right though.
    If I have to treat full pond a lot more gets added.

    Was going to do initial dose at 1.5 gram per 220 gal (ton). If it gets spent within 15 mins ( brown water) would dose again at 50 % of above. Will have sodium Thiosulphate in case fish start gulping for air or look distressed.
    Maybe rť-dose next day if i cant maintain purple water after 10 % water change

    Hope you don't mind my question on your thread, but as the experts are around, I'm scared of buying plants in case they bring diseases.

    Is it ok to heavily PP plants like Lillies/Iris etc for 24 hours to kill anything off before adding to the pond?

    Or is there a better way?

    You can indeed treat plants with PP before putting them in the pond for biosecurity reasons. They seem to be tolerant of higher levels of PP than fish are, so I wouldn't be worried about using therapeutic fish doses in a planted pond.

    People dipping new plants in the stuff seem to use higher concentrations. 20 mins in a dark pink solution will do the job, then rinse off well with tap water. it doesn't seem to harm the plants surprisingly.

    That's great info Feline, thank you.

    Been 20 odd years since I added a plant to a tank or pond as I experienced problems before, that view was firmed up when the wife added a plant to her mature tropical tank (without telling me) that had been running faultlessly with no new additions for over 3 years, and all the fish were dead within a fortnight.

    I shall PP them an increased dose. Would rather risk killing the plants than introduce a pathogen.

    Didn’t harm plants whatsoever, when I spoke to a reputable Koi dealer he suggested that it was essential that I treated with the plants still in the pond as he thought that tricadina would be in the roots of the plants as well.
    Hope this helps
