Source water could be quietly wrecking koi ponds, and this conversation with Joe and Dave Bradley from @dkoi-tv into the kind of real-world problem most keepers would rather ignore until it’s too late. If your fish look “off” for no obvious reason, especially bigger koi, this episode will hit home.Dave opens up about a brutal season where even an RO setup, advanced filtration, water testing, vet checks, and microscope work still haven’t explained what’s happening in his pond. Joe shares the same mystery in his own system, from deteriorating skin and stubborn sumi issues to fish that suddenly crash with no parasites, no bad bacteria, and no clear answer.For more detailed koi articles, breeder insights, pond advice and expert opinion, sign up to The Koi Perspective, my bi-monthly printed koi magazine: https://www.thekoiperspective.com/subscribe📱 Follow us for more koi content:Instagram: https://www.instagram.com/TheKoiPerspectiveFacebook: https://www.facebook.com/TheKoiPerspectiveTikTok: https://www.tiktok.com/@the.koi.perspective🛍️ Explore our printed magazine and merchandise:Magazine: https://www.thekoiperspective.comShop: https://www.thekoiperspective.com/store🎧 Find us on Spotify and other podcasting apps:https://pod.link/1787901550#KoiPond #KoiFiltration #KoiKeeping #PondFiltration #Koi #KoiPondFilter #GardenPond #KoiHealth #ClearPondWater #KoiMasterclass #PondLife #KoiKeeper #FishPond #KoiPondBuild #TheKoiPerspective
