15 Mistakes all Koi & fish pond owners should avoid

My 15 key mistakes that koi keepers (and indeed fish pond owners in general) should avoid making. Based on experience over 25+ years keeping koi, and observations across the koi hobby, I rank the 15 mistakes I see made most often and offer tips on how to avoid making them yourself.

Some are very obvious, some will be more surprising. Most are further expanded on in more detailed videos on this channel.

Thanks for watching. If you have any suggestions for koi keeping mistakes that I've missed please share them here 🫶🍻🍻🫶

Number 16. Forgetting to add water in the pond before you put the koi in. Apparently, they need the water in the pond for some reason.

I bought my house with a koi pond last December. My newborn was 2 weeks old at the time and this is my first house, baby and honestly my job is quite a lot. Living in Ohio, it was frozen for quite awhile but an aerator was set up so we didn’t have any losses come spring. Unfortunately, the pond wasn’t as well cared for leading up to that winter as the owner had passed away. I worked well in the spring to clean it up with frequent filter changes. However, I haven’t maintained that level as life has just been insanely busy. I feel bad, but I have kept them all alive and well. I appreciate this video as I’m making myself be better when it comes to these extra responsibilities and hobbies I have. I love watching these fish and I want it to be as ideal as possible. Thanks!

Good afternoon, sorry I didn’t catch you name. I must complement you on your knowledge and also the delivery of your instructions. I have watched and listen to many videos on koi care and this is the best to date. I have been keeping koi for 25 years and I love ❤️ my hobby and my koi.
I have been struggling to keep my nitrate level between 50 to 100 parts per million which have led to parasite 🦠 and infected koi and loosing 3 smaller koi this year. Since purchasing bakki shower and a digital vary speed pump combination 🚿 I have noticed a considerable difference in the all the readings
especially ammonia and nitrite. I have been using a nexus 210 for 5 years and added a 2 tier 80cm bakki shower ack in march to help control the nitrate. My pond volume is 7800 litres and 10 koi most over 60cm.
After watching your video I can see that a need to feed less and maybe give away a couple but not my big ghost 👻 koi Kevin 30 years old.
Thanks 🙏🏿 again and sorry for the long comments.
Regards Errol.
