Gotta admitt lernex never worked for me but watching your video im questioning if i added enough of it . Pond and fish are stunning and good luck erradicating the little buggers 👍👍
Thanks, 😀 They are really stubborn little blighters these days with increasing tolerance to all fluke treatments, they were an easy fix back in the 1990's... FMG or masoten killed everything lol...😂 I last had them in 2020 and that took over 6 weeks of treatment too. I was fine for the last 2 years, because I haven't added any new koi until recently when I added 6 more. Lernex being measured in millilitres and not grammes is an easy one to miss, they are not the same. i think it might be because the powder can adsorb water after opening the jar making it heavier, or the production weight changes depending on how much moisture is in it.
Hi Chrissy, 🙂 it's something called a 'maxijet mod kit', that converted a 1200 lph maxijet aquarium powerhead into a stream style pump, it pushes around 5,000 lph iirc... It's something I had left over from an old reef tank, probably nearly 20 years old now lol... but any reasonably powerful reef wave style pump should do. Just something powerful enough to stop the granules from settling on the bottom so they can dissolve.
@@chrissysteel3866 looks a nice pump, but I wouldn't necessarily buy it just to mix up lernex pro. I just used whatever spare aquarium pump I had kicking around. 🙂
Hi Dave, i am following your advice on this video as i have struggled with skin flukes on one large koi in partcular, for month,s after first dose of lerne pro i still find skin flukes on this particular koi., i am about to re treat , my question is can i use evolution aqua resolve for blanket weed at the same time as using lerne pro. Thanks
Hi merczuki, It's not advise, it's just sharing the way I chose to treat with Lernex pro last year.🙂 If it didn't work I would suggest using a different fluke chemical, as Lernex pro didn't work for me this year with gill flukes, Knocked them back a bit but didn't kill them all. As for dosing resolve at the same time, i'm not a fan of mixing medications. Unless you know the outcome.... Even if it's just a phosphate binder, and the instruction on the aquasource resolve say so, that would be your choice. As any chemical binding agent may possibly reduce the effectiveness of the treatment. Plus resolve takes a long time to work, about 6 weeks in total and two doses for me this year. It's a bit late in the season for blanket weed treatments, they work better in the late spring before it gets out of hand... if you have a lot and kill it all off, it will make a big mess as it breaks down....
Hi mate, i don't have a drum, Just 2 moving bed filters and a shower, do you think turn all those off, and just leave the air on to the pond for 20 mins, then turn it all back on ? Im about to do this on saturday after 2 failed treatments of FX1.
I just turned the filter pumps of long enough for the learnex to dissolve in the pond. There are a lot of people having problems killing off flukes this year, with different medications working for different people. For me after many flukesolve treatments for skin flukes, I didn't see the numbers of flukes per scrape declining at all. And most other fluke treatments cloud the water and are easily removed by a drum, so I went with lernex pro and it made a big difference within a week. It did find it quite a harsh treatment for one of my fish that didn't take too well to it, though the others were all fine... But I suspect it may have ingested some of the few flakes that didn't dissolve, as it tends to root about on the bottom of the pond a lot. And as a result ingested an overdose of the treatment and became quite inflamed and ill.
@@DavesKoiPond ahh jeez, yes i have had Trichodina and treated with PP twice, and treated for flukes twice also all within the space of a month, and they are flicking like mad out there tonight, i know its flukes we scraped the other day, but i just have to wait till the end of the week to let the previous fx1 burn off, im doing water changes to help it and stuck the uv back on, hopefully sat i can hit it with the lernex pro i bought. poor buggers been flicking and jumping for about 2 months, Did your ill fish recover ? your pond about the same as mine, 2500 gallons ?
@@BlingKingMarvellous yes the fish has lost a few mm off the tail, but is much better now. If I could reccomend one thing it's buying Duncans book and reading the whole thing cover to cover. It's more than just a 'what chemical to use book'... It will help guide you in when and how to treat, how to support the fish through treatments, or even how space out treating too often. As over medication can be as damaging or worse, especially with oxidising treatments like PP and CT. Also finding a good experienced dealer that will help with advise, especially when things seem to go wrong one thing after another...
Once only for the first treatment, yes mate. 🙂 As long as you have experience using it. 👍 Just to help thin the mucus to allow the treatment to reach the flukes. I don't do it more than is absolutely neccessary. I'm not a massive fan of PP. As I think to do it properly for parasites like Tric you really need a good quality calibrated OPR monitor, or experience from watching others do it. Anything less is a useless treatment that harms the fish more than parasites. Anything more will kill all the fish. 🙂
@@DavesKoiPond thanks for the reply Dave I didn’t pp first as I don’t like using it but I’ve done 2 fluke solve & 1 fluke solve plus treatments so far and it just isn’t shifting them. Had a delivery today of fluke m and learnex pro. 🤞
@@somersetkoi8309 after 2 x fluke M, 2 x flukesolve, and 2 x flukesolve plus treatments, made absolutely no difference to the skin flukes I treated earlier this year, they just got worse going from 1 fluke per 3 slides, to 3 flukes on every slide! I nearly lost fish because those treatments were so worthless and ineffective. After nearly 2 months of those treatments the fish were crawling with skinflukes and smashing themselves to pieces. It was only after finally trying lernex pro it killed them all in one treatment, two days after I couldn't find a single one alive. I leave my filters off for 8 hours if treating now, just to maximise the effectiveness so the biological filters don't break it down.
@@DavesKoiPond it’s horrible to see them deteriorate when we’re doing what we should be. My favourite sanke at the moment isn’t doing too well, do you know if learnex pro can be used with salt? I’ve checked the instructions and the internet and can’t find any mention of it? I’m at 0.2 at the moment
Yes mate, 🙂 It was already off from when I'd done the previous failed fluke treatments with flukesolve plus ect.... I briefly mentioned it at 8:15 but is easily missed 😁
My 2nd dose for possible gill flukes, and to make sure I got all the skin flukes, I did after 7 days at 20C. But at colder temperatures gill fluke hatch rate is slower so gap can be bigger. Also a 25% watch change is reccommended between doses iirc, and is needed as I find lernex pro much tougher on the fish than praziquantel based treatments. 🙂
sorry forgot to add i sell about 400 to 600 bottles per year and if you have persistent flukes then as long as you repeat the doses at the correct times according to the temperature i have had a 100% success rate
@@japankoiimport Yes, it worked very well for skin flukes last year for me too, 👍 I haven't had a single skin fluke since. I'm currently dosing for gill flukes that must have slipped past last year, they are proving more difficult to 100% eradicate...
@@DavesKoiPond if you ever get stuck speak to fiona who makes flukesolve plus you can go alot higher than i did you cpuld over dose by 3 or 4 times ( not recommended ) but she states they have done it but obviously some fish hardier than others ( ever wondered why some peoples doses are different in fmg evo aquas is far stronger than ntlabs yet nt labs 7 days evo aqua 4th day , evo aqua killed costia in 1 hit without day 4s treatment ,20 plus years ago the main treatment was FMG for everything 🙂
@@leeoliver4063 Thanks, 😀 I understand you can quite often dose much higher with praziquantel, That's become popular since Jos Derkin's comments on Koi Talk #007. The manufacturers seem to put the minimum dose required in the instructions on some medications. I did a full dose of flukesolve plus two half doses on the following days, but didn't work. ...and it's not cheap medication to triple dose.... My local dealer used to swear by flukesolve as did I, but now only uses lernex pro...
Cheers Dave👍😊. Thank you for sharing as I’ve not used Lernex pro before 👍😊
No worries 😀
I wish i'd known it dissolves completely with a little bit of help.
So unlike flukesolve and fluke m, the drum didn't need bypassing...
Thank you Dave. Keep sharing the knowledge.😀
Thanks, 😀
I just wish i'd had that info before I spent a small fortune on expensive fluke treatments that are ineffective with my ponds filtration. 😂
🙂
Neat potion and way to dissolve it. Glad it worked for you. Happy fish.
Thanks, 👍
The medication certainly hasn't impacted thier appetite lol 😀
