    Treating koi fluke in colder water.

    So i've gone all year without (to my knowledge) any problems with fluke or any other parasites in my pond. Came home today to find 2 fish rubbing against the bottom drain a few times. A check under the microscope and I'm finding a few fluke on the slides after scraping 5 fish in total.
    Last year I used Lernex Pro to shift them but that was at the end of spring with water up to 14-15c. My water is not 6-8c depending where taking the reading from. I noticed that Lernex Pro should be used above 10c so feel like it will be a waste using it now if it's not going to help.
    The pond is not heated so turning the water temp up is out of the question. What do other do, wait until the spring and deal with then?

    To be honest from what I have read it is not worth treating flukes under 18 degrees and they are not ingesting enough for them to die from the medication.

    i'd agree with that, plus you're less likely to be having much trouble with flukes at those temperatures they should be nearly dormant....
    it's when temps go up in spring they start multiplying like mad.
    you can use flukesolve/plus at low temperatures (not my go to treatment anymore but it claims to work at low temps), but as sam said it may not work very well.

    if you haven't had a problem with flukes all summer, could they have still been there...?
    are you sure there is not another reason for the flashing?
    parameters or chlorine?
    Chlorine levels go up in winter due to cold waters slowed reaction in the distribution network.
    and activated carbon reactions are slowed making it harder to remove in winter than summer...

    if they are not resistant skin flukes, or gill flukes i'd probably do a flukesolve/plus treatment as it's pretty mild anyway.
    it may knock them back enough to get by until it's warmer...

    Parameters are as followed,

    Ammonia - 0.2
    Nitrite - 0.25
    PH - 8.5
    KH - 13
    GH - 16

    Chlorine tested this morning from top and bottom drain to sieve and showed nothing on the DPD tests.

    My Ammonia and Nitrite always seem to go up for a few days after cleaning the filters and has never been an issue before.

    One out the two doing it yesterday has stopped but the other seems to have a 30 second madness off flashing then is completely fine for a while. I've not feed since Sunday just in-case this could be causing more issues.

    So found Trichodina today after scraping all the fish in the pond. Never had this before so unsure on how to treat, any advise would be more than welcome.

    PP is the treatment for tric, but min temperature is 10C
    and in inexperienced hands can just as easily kill every fish in the pond

    i'd advise getting someone who is experienced to do it.
    while you watch and learn what precautions to take, and how to dose and maintain the correct level for an effective treatment.

    Thank you. Never used PP before so will take your advise and try and find someone with experience to handle the product and complete the treatment.

    Without sounding stupid, is this treatment now going to have to wait until warmer weather?

    there are other treatments for tric like alparex, and kusuri acriflavin and malachite green,
    but i have no experience with these treatments, or how effective/dangerous they are. though alparex has been known to wipe out ponds without enough KH...
    and i also can't see a minimum temperature on the websites...?

    Don’t use Alparex or Kusuri Malachite/Acriflavine immediately ( up to 3 weeks ) after treating for Flukes - it can react very very badly

    PP for the tric, which will also strip a bit of mucus, and then treat the flukes with Lernex Pro - but you’re going to struggle at below 12c to be fully effective
