    treating Gill/skin flukes

    Hi guys , just need a bit of advice on best treatment for flukes ?

    have just fount my 22" koi dead and his gills partially eaten away
    he was gasping at the surface from last night having previously spent most of his time in pond pond since i took him in from a pond closure sitting at the bottom doing nothing.

    im looking at fluke solve for 3000 gallon pond at approx 11.5 c 2x treatments

    i was treating the pond for tric as i had found this under a microscope koi seemed to respond well ulcers healing scales not sticking out , eating well , but my largest koi would still sit at the bottom most of the time.

    i havent in the past found flukes

    thanks
    mark

    I used chlormine T for 2 days.
    For mucus. Then did a 20% water change
    Then used fluke M. That was this year. But a hell of a lot warmer.But now it is colder I have used fluke P in winter. Once before about 2 years ago. I dosed once. Then scraped. Then dosed again one week after first dose.
    Both worked ok.
    Good luck with it mark. And sorry to hear of the loss of your fish.
    Don t forget to rescrape a week or 2 after the treatment. As you may get a follow up parasite.
    Like I did. White spot. And a few others did.
    With other parasites. Such as costia. As immune system is down.

    Hi Fred, can I just clarify something, when you say you use chloramine T for two days is it you dose once and leave for two days or dose two times over two days?
    How long does c/T stay in the water?
    Not planning to use it but just wondered.
    John

    CT degrades within 24 hours John. Faster if UV is left on.

    Dosed 2 times. One dose one day. Then dosed again next day.
    As RS says it goes away pretty quickly.
    In my case for this reason I left UVs off.
    But did a 20% water change. At end of chlormine T.
    As I was being cautious that it had gassed off so to speak lol. And did nt want to mix treatments.

    I believe mine got them john. flukes. because I shut top pond down last winter. and used a bypass into pond. when I put covers on for the first time.
    to keep the wind chill down. well because of it. I am going to experiment this year with cover on. and keep the top pond running as well as the bypass line.
    and watch the tempretures in the pond to see if there is a difference. by keeping the top pond running.

    it was heart breaking to find him dead, at first I wasnt sure due to him floating up rite presume he had just died within last few hours
    he and a load of other koi I took in from a pond closure withn days of them being in my pond I noticed flashing, not eating
    I ended up overloading my filters with buying so many large koi and a 4ft sturgeon It was a huge mistake on my part that I now heavily regret but I was lured in with give away prices

    as I had fount more serious short term illnesses like TRIC I didnt at the time find skin fluke and on a visual examination of another koi's gill I didnt find anything to be concerned about I presume if I looked at the koi that sadly died I would of seen visual evidence of gill flukes and needed to scrape .
    ive spent some time this morning doing scrapes on all my koi and most of my new koi from pond closure are infected heavily , 4 of my existing fish now have skin flukes and early stages of gill flukes

    last night I ordered 110g of fluke solve enough for 2 treatments , from advice I received I need to wait 3 weeks before treating again and no need to add anything prior its possibly the most costly treatment at £66 in total.

    when I was getting my refund sorted via Darren at absolute koi flukes was mentioned by him as likely to be infecting my fish, and mentioned that fluke solve is an approved veterinary product with proven results across a wide range of treatments.
    I looked at Kusuri products but also read from others saying it didnt work for them but ive also heard that from those that used fluke solve maybe people aint using the product correctly, its hard to say without trying myself.

    Apologies Mark,sorry to hear you lost a large koi but we are all learning.

    We have the same size pond and that is an expensive treatment £66,but I have heard good results with it though I havnt used it myself.
    Are you going to c/t them first ?

    Wish you luck and let us know how you get on Mark.

    Good idea to keep the top pond going mate only needs a small flow.

    Learning curve mark. We learn new things every day mate. Don t beat yourself up mate.
    We have all done things at the time. And then find we have made mistakes. That's how you gain the experience.
    I have made a few.
    Now is what matters mate. To get the fish well again. And over all this illness.
    Remember the fish eggs mate. So treat the 2nd time about 12 to 14 days after.
    Fluke solve is good stuff. Tempreture 3c it can be used.
    It is also known to kill tric as well.
    So that sounds good.
    Good luck with it all.
    Fred

    For me Fluke Solve didn't work first time round. Took 3 treatments of it last year to nail flukes.

    This year the flukes were back. Temps were sub 10C, used Fluke Solve again but didn't clear them. Then I used the CT method followed by 2 doses of Lernex and it cleared them (Temps were over 12/13C by now).

    Only used the Lernex instead of fluke solve because I had some with a short expiry, otherwise I'd have used the FS.

    is your pond exposed to elements and other forms of life that can reintroduce flukes to the pond .

    if this doesn't work for me I will have to try Lernex and CT

    what else can I use to strip back the slime layer ? ive got PP, formalhyde , malachite

    See my post with PP doses to strip slime coat which is in the thread I linked to earlier along with explanation about using it compared to CT.

    My pond, whilst outdoors, is raised and covered with no wildlife.

    Couldn't honestly say whether the flukes were an overhang from the previous year, or whether I introduced them with 2 Koi I purchased from a private pond between the 2 outbreaks. Didn't find any flukes when I scraped those 2, but that's not to say they didn't introduce them.

    You can buy CT with next day delivery cheaply off eBay - Just make sure you trust the seller and that it is the right purity etc.

    1 dose of PP at 1.5g per 220 gallons to remove slime coat, followed 24 hours later by a proprietary fluke treatment.

    The other said they wouldn't use PP as it was harsh and preferred Chloramine T at a dose of 10 grams per 1000 gallons re-dosed every day for 3 days to remove slime coat, followed on the 4th day with a proprietary fluke treatment. For this method and dosage the PH must be at least 7.5

    ive got loads of crystal PP it is harsh agree ive used it a few times with excellent results on both times .
    20.45grams required for me, how long does this need to be applied for? normally its 4 hours keep it pink/purple then neutralise with HP

    thanks

    I've never used PP so can't really say, hence why I'd only quoted the advice I was given by those 2 dealers.

    Seen some PP horror stories but also heard of success stories. I'll be nervous when the day comes that I need to use it.

    CT on the other hand, used that a few times and the koi showed no reaction to it whatsoever, totally unphased.

    can understand why your put off , ive used it 5 times even with sturgeon in the water and can start to get concerned after around 3 hours due to the oxygen almost being completely removed from the water, i off set the effects by turning air pump fully on to pond airdome , and both water pumps on full 30,000l to increase oxygen and water movement as much as possible.
    fish will come up gasping , if any fish begin to roll over then you need to reverse the treatment asap with hydrogen peroxide 6%
    for very poorly fish it may well push them over the edge and they simply suffocate to death
    anyone with serious gill flukes id advise against this product for obvious reasons.

    but its the most effective treatment ive ever used on a wide range of ailments , very cheap off ebay in crystal form 400g for less than £7 I paid and take just 4 hours rather than days for other treatments
