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.
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?
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
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”?
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.
Thanks for your comments. Creating this video was very challenging for me and it took me many hours of work. I tried to answer a lot of the questions I get asked ever day. Thanks again.
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?
No experience with it. My suspicion is it will not work well long-term. Certainly not as good as fibreglass. As with any paint it's only as good as the surface you apply it.
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
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
Looking again to the piping is now clear to me that the flushing/cleaning of the filter is done by gravity only and the water pump is not involved at all. Sorry for my miss leading statement at the end of my previous message . Have a good Sunday and thanks again for your detailed video, Marco from Italy
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
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
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
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?
Good point. The pump should not be pumping water directly from the bottom. It would be better to have a void of several inches to ensure the solids are not pumped back. However most of the solids will probably be more concentrated towards the front of the filter.
Lee Calladine Thanks Lee I would be struggling for space and pound notes to put another filter into my current build anyway, is there a “through wall” skimmer for liner connection you’d recommend?
@@nigelsiviter1888 you don't need a through wall. You just need! He most basic skimmer like the one in the video. Standard in wall swimming pool skimmer.
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
The return pressure may be down to inadequate pipework. Most modern pumps don't push much pressure. Perhaps the pump needs to be upgraded. The current trend is going in favour of low pressure systems. Larger diameter pipework. This is a topic I will cover in one of the upcoming drum videos. First one out next Friday.
Interesting idea. Something I have contemplated myself. I think it would probably be fine especially below ground level. However there is no way it would be as strong as mortaring them. You could also do a pond by shuttering and concrete pour.
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
3 inch drain 1000 gallon per hour. 4 inches 2000 per hour. Bigger if doing the skimmer as well extra 1000 gallons. The best pumps are probably multi speed pumps with flow control.
No particular reason. The builder wanted to do the very best job possible and it had not been decided how the pond was going to be finished on the outside.
Lee Calladine thank goodness for that, I’m half way up with my block work. One more thing mate. With block work, I want to fibreglass will I have to treat the inside first? I’ve gone down about 1.5m in clay so have a high water table.
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.
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
Stavros Pavos not exactly sure what your referring to. But out shop in staplford Nottingham stocks a range of filters suitable for a koi pond. We can supply a single chamber vortex filter cost ranges from £55 uptown about ££200 for a large one.
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
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.
Paint is never going to be as good as fibreglass because the paint is only as strong as the surface onto which you apply it. Regardless of how many coats. Also all ponds will eventually develop hair line cracks in the block walls and render as a result of thaw and freeze action of moisture from the ground on the outside of the pond. So waterproof it all you like but it's still going to crack from the outside. Fibreglass if done well is strong enough for the walls to crack and it will bridge the small cracks easily.
@@leecalladine Thanks Lee, but aren't swimming pools painted? They are similar in design to a koi pond. Do they also have this free-thaw issue overtime? I've seen people coat there ponds in polyurea, is this the same as paint?
@@hamza361 mmm good point. I would say that swimming pools could suffer from the same problems. But normally they don't freeze. Besides swimsuit pools are not so popular in cold climates.
It goes down that hole in the middle into the filters, through the filters, then pumped to pond (maybe via a UV or heat pump) Look up gravity flow filtration.
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 😕
DXB DXB A Koi can take many forms. There is not a wrong or right way of building a Koi pond. There are many construction methods that will get the job done without the expense and effort involved in a blockwork fibreglass pool. There are many people who keep Koi in pools that are far from perfect. The fact remains however that a bottom drain system and gravity fed filter are definitely important if you want a low maintenance system. The purpose of this video is not to put anyone off building a garden pond which is somewhat different to a Koi pool.
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 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
In the UK planning permission it is not normally required for the construction of a pond. The methods outlined in the video are sufficient for most peoples needs.
The water from the skimmer is pulled through the basket. It removes large particles such as leaves, un eaten food etc. It then combines with water being pulled through the filter system. The pump then pushes water through the UV and returns if to the pond.
@@leecalladine I can see that Lee, but you see I followed a lot of your ideas in your video but this I omitted, I did try it but then changed it, because the skimmer not just take out the largest particles but a lot of small particles as well, I live in Brasil where the weather is hot 🔥 most of the time so you can imagine the problem with algae growth, so I still think it's not a good idea, but I must say I love watching your video's, cheers ps I NOW FILTER THE WATER FROM SKIMER SEPERATELY, MY POND IS CLEAR AS GLASS.

Skimmer has a basket inside. Collects the rubbish. Also stops the unsightly scum and froff on the top.
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?

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”?
3in bottom drains. 1.5 in pump return. Pump is pushing water . Bottom drain is not under pressure.
Excellent piece of work, exactly what I needed for a project. Thank you.

It's not waterproofed with paint. Fibreglass would be better. The rebar might not be needed if the ground conditions are good.
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?
The filter would drain better if the chamber slopped towards the valve.

can you add the flowcoat onto a rendered surface without the glass sheets?
Yes. But it is going to be extremely weak. The whole point of fibreglass is that it is reinforced with fibres that increase the strength.
Paint is never going to be as good as fibreglass because the paint is only as strong as the surface onto which you apply it. Regardless of how many coats.
