Catching and Measuring My Giant Pet Koi... 

6:35 made my heart melt, you take such good care of them, admire them and keep them healthy, its such a big task and to do so happily is incredibly sweet, thank you for sharing these moments and process💗

Carl, for the new tank you must *do the cold-water, high-flow river/stream tank with NATIVE UK FISH* like shoal of stream minnow, spined loach, and shoal of gudgeons. (Thats a whole episode with nets, undewater cameras and waiders) For aquatic plants use simple Vallisneria, it will look absolutely brilliant in the flow and is super low maintenance. No CO2, low light. The most expensive unit will be the chiller and larger turn-around filter + powerheads. Use natural gravel, I prefer it to come from the beach, you will get more varied sizes and that contributes to the natural look. Add large pebbles and rounded stones. Make sure you internalize recent aquascaping techniques by watching : "HOW TO BUILD THE PERFECT AQUASCAPE FOR CONTESTS - BY WORLD CHAMPION JOSH SIM"

Carl, for the second tank you could handpick some baby Koi. Then watch them grow from Tosai to Nisai. And watch how coloration and patterns start to grow and develop on every individual. In the end you can keep your most perfect ones for the large pond.

I actually loved that you picked the common goldfish, they are the most elegant to me.

Hi Carl, I would think twice about the climbing plant above the pond, as it will increase your pond maintenance, with falling leaves and depending on what plant it is, it will turn your water pH levels up or down.

A wonderful video, Carl. I love everything you do, but I have to admit your koi videos hold a special place in my heart. You take such good care of them, and they are so beautiful it just melts my heart. ❤️ And your garden is just stunning!

Its so great to see you looking after your fish so well! Some people will buy them and keep them in terrible condition and not feeding them.

Finally Carl's back in town .

That is the most beautiful back yard pond I have ever seen. You can be very proud of it Carl.

A video from Carl is ALWALYS great and entertaining to watch!!! Keep up the good work! Thankyou Carl.

Beautiful fish, lucky that in the UK there aren't really any predators that would snatch the fish.

Love your videos it is helping me through a hard time after my dog died. Thank you for making videos that make me happy.😊

Koi fry for the tank carl, we currently doing that to grow them on. Non heated tank just at room temperature. Nice to grow them on and see what we get in future. They growing fast!

Stumbled upon your channel by accident and love how wholesome your family is, I’ve always known about koi but never appreciated their beauty until I watched your videos. Typically I enjoy fresh and saltwater fish. Now you have me planning a pond of my own in the not so distant future, I was wondering what are some things you wish you knew before hand? How expensive is a quality koi pond? What is the price range of various koi? (Is it cheaper to buy juvenile koi and grow them out yourself?) and lastly what is the general space rule for keeping koi (how many/ ____ gallon(litre) I thought these points would be good for an introductory to koi video that I may selfishly love to see what you have to say and may give you an excuse to get back out to Japan :) keep up the amazing work Carl!

You should put some rocks and plants in the pond hun. Ours are 35 years old,the oldest ones,and they like lots of oxygen,some rocks here and there,and yes it's necessary to keep their water very clean. Its necessary to spend some money for proper equipment. The pond is gorgeous and so are your fish. You're doing well

Car I absolutely love your back yard. My grandfather has a pond on his property that he had over 100 gold fish put in. About 20 years ago the neighboring brook flooded and wild speckled trout had got in. Long story short we now have gold fish with trout spots all over their sides and trout with long gold fish fins and a goldish color. Cheers

too beautiful fishes dzam, havent expected that peoples can love fishes that mutch but now by seeing it dzam these pets are so beautiful and growing so fast. so nice content man lovely to watch Keep this content goin man big Respect.

The fish look stunning Carl! I love the pond , and you’ve done so well with your garden ! Keep up the amazing work !

Hey Carl, I had commented on your past video in which you built the koi pond. In that comment I talked about how I have a short attention span and that your video helped me find some calmness. Recently, I've hit a rough patch in life and have been stressing out a lot due to it. That's when I remembered about your channel, I searched for an update about the koi pond and came across this video. The gentle and wholesome vibe your videos have is something that I think is really precious, it helps me calm down and brightens up my mood. Your videos, you and the koi pond have become a comfort space for me which I come back to whenever I feel low. Thank you so much! ❤

Fantastic mate. New sub here. An Englishman (32) living in QLD Australia and enjoying your videos with my 3 kids (5, 3 & 2). Thanks for the awesome content! Please keep em' coming!

Keep the videos rolling mate, always exciting to see what you drop next on your channel!👌

When I first saw your koi I thought they where massive but now the smaller koi have got bigger the pond Looks amazing. keep up the god work (:

this is/was my 1st video I am watching of yours Carl and I must say....... I'M IN LOVE Your Koi are magnificent and a treasure to watch. Your backyard is perfect. Your husbandry is marvelous and your pets are very fortunate to have you as their keeper! Thanks for the video I look forward to watching the rest and any new drops..

Another video of you that has brought me genuine smiles. Thank you Carl!

I was also thinking of starting a koi pond! I'm glad I stumbled across this video as it will help me learn how to take care of these gentle giants🎏

Haven’t been on your channel recently because been busy with work but can always rely on a relaxing video from you Carl !

Nice to catch up with you @ Brentwood today Carl! my son now has his signed poster pride of place on his wall..... thanks again!

Hi Carl. Not seen any of your videos and don't even know why RU-vid recommended this. I used to have a Koi pond at my old house 20 or 30 years ago.. This is before the days of bottom drains and pump/filter rooms I had 2 huge cellar pumps modified with pre filters and 3x 50l garden water butts with my filter media in . From memory the pond was around 2500 gallons and the pumps could exchange all that water through the filters every 3 or 4 hours. Water was always lovely and clear but every year or so you had to de-poop the bottom of the pond . The Largest Koi in the pond were well into double figures but not over 20lbs. about 20 years ago my father in law re-dug his pond deeper fitted 2 bottom drains and dug a pit to house 2 massive filters. He actually took all our large Koi when we moved. And why most have since died he still has a platinum Koi that was about 9' long when he had it from me thats now around 20lbs. Loved keeping Koi couldn't afford it now!

you should of built the the fish pond glass windo into the wall of the house then you would have have and inside tank and outside pond all in one ☺️

What a stunning load of fish and the garden looks brilliant! This video of yours Carl has cheered me up no end as ive been suffering with bad health atm and seeing your koi and goldfish so healthy and happy in your pond is a delight to see!

Hi Carl, great video as always. Wow the fish are amazing as is the pond. Thanks for updating us all.

Loved this video! Nothing serious & easy watching! Plus it’s always a pleasure seeing your gorgeous garden and pond! ❤

Would it be ok to put in some plants in the pond with them? It just looks very empty and dark in there

U done an amazing job on this project Carl and it’s so loving the way you take care of you’re fish ❤❤

Absolutely love your pond and garden thank you so much for the update 😊

You and your brother Alex have the most amazing way of making video’s. So easy to watch. A bit of advice with your koi pond. It would be a good idea to fit jump guards when you haven’t got the covers on.

Thanks again Carl for another amazing video!!❤It is great to see your fish in tip top condition and how big they have grown over the years (They are huge) and it is brilliant to see you trying your best to keep your fish healthy during the cold months. Well done Carl!!!❤🎣🐟

Oh wow Charlie's always been big....happy to see all the koi.

Fishes are such lovely creatures! Magnificent Channel. Thanks for the content

Great video my friend . I was so happy to see this show up on my feed this morning I look forward to Saturday because I really do love this channel!! The fish are getting so big and are looking great!! Keep up the great work!!

Cracking update Carl, you really have some fantastic koi in that pond, oh and goldfish ! It’s all come together and looks brilliant mate…… 👍🏼

Really good show Carl , nice to see your fish again and just how much they have grown. Interesting. Nice cover for the pound too .

7:00 gotta love a little bump of Charlie every now and again

You HAVE to put some gudgeon like fish in that other tank i reacon also to have some flow in it to represent a river great vid Carl thumbs up 👍

The pond turned out splendidly.

My grandfather ran a commercial greenhouse in the 1950ies. In the potting shed they have an oil drum buried in the ground, and surrounded by concrete, They had a half a dozen spotted carp in there, about 6 inches long. No filters, no special feed, they threw worms in occasionally and used the water fior some of the plants.

Love how this pond has developed since it was built it’s like a fine wine looks better with age 👍👌

Thanks so much for sharing mate :) Very enjoyable to watch!

Hi carl fish are all looking good and healthy. You've all done a great job of the covers.

Carl great video, now seeing both you and your brother on youtube is great. You two are so like each other.

Your pond and garden are stunning as are the fish in the pond 🥰

Lovely fishes Carl. Really chuckled when Omi dried her hands on your shirt. Totally oblivious you were. 😁

Good to see you back carl

Hi Carl I think it is great that u have pet fish and giving them a great home

I love your channels Carl and I also love fish. Personally I would prefer to see your Koi with an enriching environment i.e plants rocks etc in their pond.

Happy to see your koi thriving and growing so well hope to see more fishing vidios

brilliant video always brings me joy and i think that new tanks in the corner should be a plako tank

You got some very healthy happy beautiful fish there.

Great video....big yellow is BIG...also cool how big the goldfish is now that he / she has room to grow...

You should get one of those pleck fish that eat the algie of the walls of the pond they get really big as well

Love your videos fishing and fish tanks. The pond is looking incredible I’ve watched from day one of the build. Now I know you have a empty aquarium I really think some discus plenty of colours and sizes

The fish are beautiful and the cover is real nice.

Cant imagine how big those carp would be, this is only a video.. Nice Video carl!!!

For the new tank, local UK fish would be awesome to see. Would tie it into your fishing content, as well. Excited for whatever you end up going for!

Love that they got their own names.

ahhh yes those 4 days of summer, the fish will really enjoy that shade. ahahahaha just teasing, garden is looking amazing carl and the fish seem to be happier than ever!

Malawi Cichlids in the new tank. Very easy to maintain and keep the water clear and the fish are active 24/7 so the tank is very relaxing to watch.

I used to keep aquatic plants, it's what I started my channel on. It really is a labor of love to keep planted tanks healthy.

Hope you had a good Xmas and New Year Carl your looking forward to your videos this year & you're pond & carp are looking quality 👌

Another excellent video, nice to see the koi.

Such beautiful serene creatures .Well done

Great vid and this is the most exciting part of owning a pond for me. One thing i would recommend is to have a hole in the poly for gasses to escape. Your pond will naturally produce gasses that need to have somewhere to go.

Use the new tank as a grow out tank for more koi!!! Then you can film the journey from tiny fingerling size koi up to huge fish like Charlie 🤩🤩

That was great to see. Thanks for sharing that us.

ooo oooo Carl get some Tanganyikan cichlids for your second tank ,they are a truly fascinating group of fish

You should get A common pleco for the pond to help get rid of the algee. And for the empty tank a european river scape would be amazing

Just a lovely pond

Great video what gorgeous fish, was laughing my head off at Omi drying her hands on your sleeve

been waiting for this video 😄

Your video making skill is non less than Amazing Carl 🤩🤟 i really love your videos especially your koi videos. Thanks for sharing ♥️

Great video - Lovely to see Omni Carl

So happy to have finally met you today was a blast at the show

Awesome video, met you at the the Essex Carp show a couple hours ago, a dream come true. Tight lines !

Enjoyed this one. The fish are beautiful.

Great as always

Nice job Rasta

Hi Carl, to insulate your pond. Try those packaging airpillovs that you can buy everywhere they sell packaging material. Really good insulation and they let light through. Could be placed under your plastic sheets 👍

Watching this is so relaxing 😌

You might want to consider Loaches for the large tank, highly sociable species especially in larger groups.

Great video loving the carp for your new tank look at South American chiclids they are so colourful

Karl make sure you have a big gap in that poly carb..... Its so important. Also u need a bigger net and to feed more, loads of growing left in that karasigoi 👍

The little fish kiss

Great video, thanks Carl 😎👍

Let’s gooooo new vid can’t wait for the next one keep up the good work mate

Stunning colours They are the bomb

Lovely looking fish ❤ Have you thought about putting a common or mirror carp in your pond, the body depth would look very impressive through the window - could put a young one in your aquarium and it'd grow like wildfire. My koi pond has some very nice koi, one enormous ghost koi who will be 40 this June and her granddaughter who's a late 20lb common carp - I love those two fish as much as any of my koi !

Carl, You should defenetly make a tropical tank in that empty tank in the room. With much smaller tropical fishes, driftwoods and lots of plants. Don't worry about the algee. Put 1 inces of dirt or mud (collect it from a nature lake, or river) on to the bottom of the aquarium, 2 inces of sand on top of it, add some driftwood, and rocks plant the plants 1--1,5 inc deep into the sand, add 1 inc of leaf leathers the top of the sand, the water and the fishes, some algie eaters, coridora catfishes, Kuli loaches, a large group ot neon tertras, rasboras, guppies or any type of this will thiving in there. You can add shimps, and snails too. Feed them 2-3 days and dont overfeed them and it will be fine.

Ah! They look amazing! Also that’s one beautiful goldfish ❤

What another amazing video it was great to see your fish keep up the amazing work ❤️❤️❤️👍👍👍

As always your videos are entertaining to watch
