This is by far the most helpful video on ponds on KZfaq. I cannot tell you how many times I have watched it. Thank you very much

Loved all the night shots. And that Japanese Garden!

Will be using many of your ideas for my third pond. Thanks for taking the time to make this video..

Just the video i needed to explain the pipe work for a bottom drain installation. Very effective filtration system and all hidden away. Cheers

Hi Lee. Thanks for your help and advice this weekend. Brilliant video. Speak soon

Great video. Really liked it. Can't wait for your next one. 10 out of 10

Great video and really helpful. Built my first raised pond this year with railway sleepers and now want to build a pond along the lines of this in the video. Thank you.

an excellent video one of the best I've seen on pond building

brill just what I need ,keep up the good work...

Excellent piece of work, exactly what I needed for a project. Thank you.

The Video is very useful... thank you.

Brilliant video mate

Great video..

best video yet.

Seriously... Wow... 👍👍👍

Excellent advice thanks

Great video thank you 👍👍

Wonderful video, would love a more detailed vid! Thanks

thank you dear its very nice video

Thank you, very detailed video

Greetings from the USA! You do such wonderful videos. We have just built a 6’ square pond and was going to use the blue food barrels. But the Mrs. Now wants filters more hidden…soooo I’m using several heavy storage chests, ( like ice chests) parallel. I was noticing your horizontal one on this video but never saw another with speciics. Yes, I see your diy using vertical food barrel . Have 2” drain and reducing to 1-1 1/2” for filtering. Thinking of placing several dividers to channel flow with flow moving over then “under” as water moves horizontally. Considering, lava rock,brushes and Jap mat and and in 2nd cooler K1 and pump. What order should these come in first to last for minimal scrubbing? Hate idea of so many, hosing netting, rags and even mats…but…thats what we may do. You’re such a gentleman and your work seems very fulfilling. Many thanks for the education…your ponds are fabulous Alan

very useful video thankyou

Awesome, thank you.

Nice video, done very well.

Very helpful information! Fail to plan Plan to fail As always!

Absolute god send of a video. Having to redo my mums ponds and just what needed. Can I ask, what is the purpose of the skimmer outlet line going to the pump surely it pull the skimmer waste and just put it into the return to the pond? Or does the skimmer hold the debris in the actually unit?

what is the name of the pump that was shown in the video thank you this video was great my name is Edgar I live in New York and I found this video very helpful thank you

Any more detail on the pipework Still a bit in the dark Cheers

Would you be willing to share the 3d scene you have in this video? I'd love to pull the objects of the concrete blocks, pipes, skimmer etc into my own 3d design for a pond. Thanks for the video. Great stuff.

Thank you

Thanks

amazing video I don't know how many times i have seen it :) I just have one question. Can it be refilled directly along the buried walls with existing soil masses? Or do you need to scoop gravel against the walls?

Lee is the use of brown drainage pipe with solvent weld fittings good enough for bottom drain?? Lots of people keep advising me to use class e pressure pipe, seems like a lot of money for this pipework in 4’’, many thanks in advance

fantastic video, makes me realise everything I have done while building my pond is wrong. Now i need to temporary house my fish in a paddling pool and start again. Is there a premade filter system like in the video you would recommend or is it best to build your own please. For the record Im not worried about doing my pond again even though hard work and all has to be done by hand because of access

no thank you buddy for the video verry handy tips init. i want to make a bigger pond hopefully 12 x 12 and 7 1/2 deep will be 4 1/2 below grownd and 3 above with 2 1200mm w by 600mm h windows will be concrete and g4 pain but not sure weather the gravity feed the filters or pump

The ruber liner can be cut and heat welded at home.

Is cementing bottom essential? I'm using liner cant I bury the bottom drain in soil?

Thanks for the comprehensive guide and tips how to get a new pond done professionally. I really liked that you used 3D plans rather than pure fotos/videos. For me, it made it easier to get to the point.

I'm considering a koi pond,use like someone on the job so all runs smoothly

Hi Lee, very interesting and pretty comprehensive, thanks for sharing. What about the size of the water pump required for the described pond ? in other words, what is the water flow required (liters/hours) ? If I am not mistaking we are taking about a total of around 24000 liters of water (22600 liters in the pond + roughly 1400 liters in the filter). Last but not least, the pump should be also capable to flush the filter fast/efficiently enough, for the weekly cleaning process (around 1400 liters of water in the filter). Right ? Thanks and greetings, Marco from Italy

How clearly he is describing.... why there guys to dislike it... pls point out where he is wrong mates

This is an amazing video. Thank you! I am hoping you can answer one question I have… If the pond we are building is 2250 gallons, should we use 3” pipe everywhere instead of the 1.5”?

We are family- I have the bell on. This is so awesome great ideas, great building.

Hi Lee/ Great work! What are your thoughts on dry stacking the blocks and then back filling with cement and rebar? Thank you!

very very useful video. thak you. were can i find this green vortex barel???

ra mudeng.. wkwkkkwkwk neng apik..

Have you done a railway sleepers pond?

Hi lee, could you place return pipes between the block work? So run the returns under the pond like the bottom drain then up through the hollow part of the brick then cut a hole through the block into the pond to completely hide piping? Thanks

Does the skimmer and bottom drain pull from the same pump ?

Hi Lee I have watched the video that shows the pump is connected to the surface skimmer and then to the uv light then to the bottom of the filter.Will the crap from the bottom of the filter be sucked back into the pond?

What you call that white under the bars. If i use other materials it wont be even thats why i need that.

Can i use liquid rubber for waterproofing this kind of pond???

Superb! With regard to the skimmer line not passing through any filtration, is this still effective?

Hi Lee, very interesting video, thanks a lot. What about the size of the water pump you would suggest to use for this pond with gravity filter ? Cheers, Marco

Is it possible that i can get that autocad file.

Will the debris that goes inside the bottom drain can come out on the filter box even if the pipe is higher going thru the filter box?

Hi Mr calladine, can you advise me please? I'm building my new koi pond and it is from block work and being painted. It was made 3 years ago but this year I'm emptying it, changing paint colour and making improvements. It's 6m x4m wide and long. In all its 55000 ltrs, I have a 2m blade but wondered how many jets should a pond this size have? I currently have 4 but I'm not happy with it and have a very very poor return pressure. Would 2 jets be OK? They are eyeball jets. Many thanks Andy

Why does one need uv in the filters or even ar all

Why do you recommend rebar if its waterproofed with paint?

I don understand the skimmer part of work . If you connected with filter outlet a T shaper with pump. Then you are not cycling dirty crease on surface of the pond at all unless it goes to another wetland or bakki style system! Please let me know , thank you

I want do the project in the Gambia I need urn help sir please

Lee, why in the new pond build series did you use engineering bricks for a damp course layer but not in this pond construction.

Hi Lee, where you from ?

can you add the flowcoat onto a rendered surface without the glass sheets?

Where does the oasis pumps go to get the water out the pond

I think i gonna pass on making koi pond. That empty backyards kinda looks better after watching this video.

Do you have a material list for this pond

Bit basic the shape. but video is good.

Great video with lots of information but it’s kind of put me of slightly because I was going for standard pond with a good quality liner and no bottom drain but looks like I need to win the lottery to have a decent koi pond 😕

I believe that the water table in my backyard is too high for this kind of project. The hydrostatic pressure underneath the pond floor during a rainy season would disrupt its integrity and crack it.

Where is the bottom drain piped to?

The FILTER THROUGH THE UV BACK TO THE POND, THIS IS WRONG, PLEASE EXPLAIN!!!

This is one approach to building a koi pond but there are other approaches that might better fit your needs. I like to use EPDM liner, which is what he calls rubber. I would not put a drain or any other perforations in the liner. A waterfall pump at the lowest level will carry most of what settles to the bottom in to the filter, which could be a chamber behind, and slightly higher than the pond. Water flowing out of the filter creates a waterfall as it pours back in to the pond. I use several layers of fiber mats in my filter which I have to cleaned periodically. I pump the muck out of the filter using a sump pump when I clean out the filter. I have many large koi and many plants in my pond which has its challenges but can be done. I would never make a pond deeper than I could stand in safely, so mine is about 5 feet deep. I have terraces at the 1, 2, 3 and 4 foot levels for plants and so that I can walk in to the deepest part. All bottom surfaces should be perfectly flat so you can walk on them even when the liner gets covered by algae and is very slippery. I used wood timbers to hold my sandy soil in place and carpet remnants below the liner. A pond like this requires extra stuff like the sump pump but is simple.

THE DIRTY WATER FROM THE SKIMER MIX WITH THE CLEAN WATER FROM THE FILTER INTO THE UV FILTER BACK TO TOE POND, THIS IS WRONG PLEASE EXPLAIN!!

where is the rubber seal between the block work and the base you dont use brick to support the mesh thata the last thing you use ask any building inspector

15 mins in and its most excellent so far. However.... i am driven to distraction thinking "This is Adam Julyen talking". I stopped watching and just listened. You are Adam Julyen right?

I bet it's much harder in "real life" then on a computer program. What a wolly
