Building A Massive Backyard Koi Pond (pt 1)

Building a fish pond for koi in my garden! This is an aquatic project I’ve dreamed of since I was a young boy. Watch the full pond build series...
Part 2: • My Backyard Koi Pond I...

I would get several smaller fish, in a variety of colors so that each is unique and easily identifiable. Watching them grow and being an integral part of them living long healthy lives is one of my favorite aspects of keeping fish.

[@DerekDogsforSentience]

👏👍

[@_Shinasu]

Yeah don't most species grow comparable to their environment? I guess the only worry would be you wouldn't want them too small for the carp to eat them

[@bonsaibaby8257]

@@_Shinasu you get the carp as babies so that you get to watch them grow. It’s the best part!

[@MrAnderson321]

🎏An exciting upload Carl! Personally I’d of started with good quality smaller Koi that were a lot cheaper to buy, not the larger more expensive ones you were looking at. Your followers would of watched them grow over time and with a pool that large they’d of grown quite fast and we’d of got attached to them. You could maybe do a competition of the naming of the new fish? Keep them coming Carl, loving this. 👊

[@localhouseshitter7213]

I think Kireina would be good name! Means beautiful in Japanese

[@MrAnderson321]

@@localhouseshitter7213 That’s a good one! Let’s hope Carl goes with the idea of the naming of the fish competition. 🎏👍

[@stephenboyd4934]

Makes my 1000ltr tank / pond look tinny in comparison, I move last year where I had built a brick pond with a linner so needed a quick option. Someone gave me this 1000ltr plastic & ally framed Liquid container. Will build a newer pond soon hopefully around 5000ltr.

[@fishwithcarl]

Nice 5000L is an ideal size for koi!

[@paulbryan1094]

Carl, you NEED that orange fish. The black outline of the scales, amazing. If you don’t get it you’ll always be thinking about it. You know you will 😁

[@simdoughnut659]

I always recommended my clients start with a 4-6" Koi. Part of the joy of having and raising Koi is watching them grow and training them.

[@neilhubsch8682]

Hi Carl. Love the video. My opinion: Start with a variety of sizes and types. There MUST be some Sanke, Kohaku and Showa in the pond, that is a given. Then maybe a nice Goshiki, Asagi or Ochiba, don't forget to look at Doitsu koi, their scale patterns can be really nice. Lastly, like I said, my opinion, NO GIN RIN or BUTTERFLY koi.

[@TheKoiPartner]

Waiting for this video Carl 🙌 Great OASE supported this project! 🏆

[@Baidelaidlgekocht]

Me too!! I love koi pond buildups and especially carl ^^

[@localhouseshitter7213]

I love your channel! So cool you are here with another cool youtubers comment section

[@fishwithcarl]

Glad to hear!

[@EnjoytheQ.]

Sod the neighbours, love it love it love it!! It’s looking goooood!! Loving the idea of the lights that is gonna be magic

[@jamesdawson5905]

Carl, initial fish size is going to depend a lot on heat, growth with heat can be extraordinary (particularly in summer/Autumn) not to mention the health benefits of stable temperatures. Presumably on this type of build you will also be heating? You’re obviously already hooked, but it’s going to get much worse, with the real quality costing crazy money, for that reason if heated, high quality tosai to grow on, and it’s the right time of year coming up for tosai. Hai good said that the Aka Matsuba was lovely!

[@fishwithcarl]

Love that matsuba! Yes I'll be heating it :) And you're right about growing on little tosai! Definitely would love to do that one day, but for now I think I'll go for instant impact with this pond.

[@alexpage7292]

Absolutely epic Carl! Can’t wait to see the progress on this pond build 👍🏻

[@tolovly14]

So Happy for you! 😊 The medium bright orange kio was absolutely beautiful. Even though it's a little bit out of your price range you should look around for one just like it for a slightly better price. Can't wait to see part 2 on the kio pond.

[@darylnz5845]

Shout out for the sponsors..thanks guys..awesome

[@fishwithcarl]

Cheers Daryl! Yeah big ups to Oase :)

[@katiepettet2760]

I would love a asagi, they are so pretty with the silver body and a bright orange in the fin and round eyes beautiful. Plus great video of the pond build you are giving me inspiration

[@fishwithcarl]

Cheers Katie, glad you found it inspiring!! :)

[@Senno_101]

Can’t wait to see the mega drone footage when it’s all lit up at night carl 👍🏻 And that’s one hell of a setup already looks incredible. I think you’ve given everyone a good vision of what it will be like 😎

[@finlaysfishing2677]

Finally!!! Its here the pond build... been waiting for this one all the best carl hope your well buddy 👍 👏 🙏

[@thecarpingsaint7143]

You had the most important job of all Carl….making a good cup of tea and endless supply of buscuits is vital for keeping the hard working design team focused ☕️🤣 Seriously though Charlie and her friends will love the new pond and i am sure will be able to grow massive. Have you seen the recent instagram clip of Mark Pitchers and Harry Charrington hand feeding a 50lb common carp in a pond ? Another brilliant video Carl and looking forward to seeing more of this years exciting projects. Keep up the fantastic work 👏👏👏

[@jasmijnariel]

I see a trip to japan coming😛🤣 A ghost butterfly koi like i had would be amazing!

[@robertdavenport4225]

One big koi is always preferable to lots of small ones in my opinion for several reasons. Larger fish are less likely to have problems as they are already passed the "young" stage where problems often frequently. Quality rather than quantity - spend on one good fish rather than lots of small ones. A couple of smaller one to grow on is always fun but heavily stocking a pond as I'm sure you are aware is asking for trouble. Large ones become friendly quicker too !

[@Mikemkp]

Looks like it’s going to be a awesome pond with great filtration and wonderful koi 😀👍🏻

[@fishwithcarl]

Can't wait! Cheers Mike :)

[@thepeoplespond]

Wow that’s amazing Carl!! 👍👍 Going to look a monster and glad you didn’t go just for a rectangle pond Oase and the pond specialist..Me Next please 🤣🤣🤣

[@denisbilkey4033]

Hi Carl, tancho sanki, love em. With koi the beauty is everyone has a different taste. I would personally get some very good quality Nisia and grow them on, sell what you don't like and fund the next buy, problem is you will never have enough fish or a big enough pond or enough filtration lol, you will always want more lol

[@reedi8279]

In my opinion u should add at least one kohaku (small size to see it's growth), shiro utsuri, and maybe one sturgeon?

[@zeus749]

The pond looks amazing I can't wait for part two. One question don't you rent? How in the world did you get the permission to build this?

[@niceguygamerdsl9796]

Adds value to the house I guess🤷‍♂️ if he left and took his koi doesn’t cost a lot to stock it with smaller ones

[@darrylclarkson1799]

@@niceguygamerdsl9796 Seriously limits who will want to rent or buy as that will cost a small fortune in electricity alone, my lads normal pond was 500 quid a year on his electric bill alone.

Cheers!! Part 2 is out on Saturday! :) No the house is owned.

[@vondeanseltapales2830]

For me, I want my pond full of Gosanke varieties only and some one colored kois such as karashigoi and chagoi ♥️. Greetings from the Philippines 🇵🇭. Love the content!!!

[@markclayden7654]

I went for a mix of colours and varieties in my 4000 gallon pond, but i bought them all quite small. For me, part of the joy of fishkeeping is watching them grow and flourish, but its nice to have a few bigger spcimens in the pond at the start too :)

[@markclayden7654]

Looking forward to part 2 Carl!

[@fishwithcarl]

Nice!! Sounds amazing. Yes watching them grow is so satisfying :) Cheers Mark

Whatever fills your heart, you only live once. That red one was beautiful.

Thanks mate, appreciate it.

Looking good! If it was my pond, I'd stock it with 10-12 jumbo Tosai or Nisai and enjoying watching them grow

[@he_91n56]

Charly is already a one colored fish. I would get some midsize ones with some more different colors. The red and black one is super cool

[@tomwinterfishing9065]

Exciting stuff! When I built my pond, I'd just started going out with my missus. I had her mixing up concrete and everything, and consequently knew she was a keeper and we'd be together forever :)

[@fishwithcarl]

That's nice :) great you got involved with it together. Cheers Tom!

[@tomwinterfishing9065]

I needed some cheap labour 😉

[@fishwithcarl]

Hahaha

[@skaramanger_144]

I think one colored kois without stains are the most beautiful and esthetic ones. I would only put these in the pond 😊 The red one is beautiful too 😍

[@jackfrancis5865]

I love the darker koi withbthe orange and reds! They really stand out to me! I cant wait too see then endddd

[@fishwithcarl]

So calming to watch aren't they :) Cheers Leigh, appreciate it. Pt 2 nearly done, and will be out v soon!

[@1paparico]

Brilliant stuff. Nice to see quality work being done. When I got my house I thought it would be nice to have a small pond 5x3x3foot. My friend had a pond like yours,and for years he tried to breed fish to no avail. He gave me 4 small carp to start me off, nice. So Iam looking in my pond with the grandaughter and she says, look tadpoles!`` l looked...fry..54 babys later I am giving away fish to anyone who can take them...even though its a lot of work,its so emotional interacting with nature. Cannot wait to see your ponds progress.

Going to look amazing. I got the inspiration for my tiny sleeper pond from your original pond and I love it. If I was building a pond like your new one I’d start with the smallest koi I could find so I watch them grow and develop character. Can’t wait to see it finished. Not jealous at all lol.

Hey Carl! I absolutely love that you’re showing us all the steps of this process.

With the centrepiece being an Asagi Koi.
