    Opened the by pass valves on the drum so it didnt take any out for 24hrs,within 3hrs of the first treatment koi improved and within 3 days no flashing so maybe it works for some as it seems to have for me.
    Hey John thanks for the feed back. Interesting that you had success where others have failed.

    Didnt seem to bother them at all as it is a week solution,but if it does the job Adam its ok for me as the solve is very expensive but probably a lot better.

    Whilst on this subject, I understand temperature has an effect on the speed at which gill fluke eggs hatch. Fluke Solve suggests a second dose in three weeks. Should this be sooner at 15C, 20C etc?

    Thanks.
    Ian.

    Cant answer that one,i believe re-treat after 6-7 days for eggs so that is what i have done.

    Bear with me whilst I spout out my own findings from extensive, but often contradictory, reading.

    Fluke-Solve is claimed to stay active for 3 weeks.

    However, I read a scientific study where the active ingredient, praziquantel, used in a *marine environment was still present after 7 days but substantially reduced at 14 days, then untraceable after 21 days.

    The 2nd dose was was only present for 3 days before substantially reducing and becoming untraceable after 7 days.

    When tested in a clinical test marine environment that contained no living organisms or bacteria, the full dose was still present after 3 weeks.

    They concluded that in an environment containing fish there is a microbial breakdown of the praziquantel and this breakdown gets faster on each subsequent dose.

    Fluke eggs hatch after 4 - 6 days in summer temps (mid 20's) which should be captured by that first dose of treatment. In cooler waters it takes longer, even Months in very cold water. Lets assume in current temps of around 16C it would take approx. 7 to 14 days for eggs to hatch.

    I read (on this forum I think) that hatching flukes take approx. 10 days before maturing enough to lay eggs themselves.

    Based on all that (which may or may not be factual), eggs that are laid in the days leading up to the first treatment, in current temps, could hatch anywhere from 7 to 14+ days later, right at the point where the praziquantel is rapidly breaking down. But, it would still take the larvae another 10 days before they themselves have the ability to reproduce.

    So fluke eggs hatching after 7 - 8 days may survive the first treatment, and can then lay their own eggs from around day 17.

    My conclusion from all that would be to do the second dose before day 17, but bearing in mind that the 2nd dose may start breaking down as quickly as 3 days after putting in your pond, I'd be inclined to re-treat last thing at night on day 15 or first thing in the morning on day 16.


    * Note the study (which I can try and find a link to if anyone interested) was carried out in a marine environment and may or may not apply to freshwater.

    Don't take any of the above as gospel..... I researched it simply because I keep reading about treatments failing and I wanted to understand more about the flukes life-cycle to try and understand if treating on the wrong days is causing the failures.

    Well I've been to AK today and bought x3 packets of fluke solve that costs £135. I asked the very same question as you have on a different forum Ian about when to retreat. The advice I was given for treating at 21C was 3 to 4 days. In the case of persistent out break it's recommended a 3rd dose with a different type of fluke treatment.

    But why would you retreat after 3 to 4 days when the first dose is supposedly still very much active?

    I agree about the potential need for a third dose especially in cooler temps...

    It's not easy to gain any certainty, especially when different treatment manufacturers selling the same active ingredient recommend different timescales to each other, let alone what you read on forums from people's real life experiences of treatment which often also differ.

    I’ve had a few people recommend me Kusuri S. I’m about to try it as I’ve had very stubborn flukes all spring & summer

    I once treeted my quaranteen pond with Fluke M - seemed very good at killing flukes - diddnt save the fish though, that died of an underlying condition. I now don't treat for flukes - keep the water good and symptoms pass in a few days - I have never lost a fish to flukes.
    6000g unheated in ground koi pond
