Hello from Tenerife! I have also comment in the previous video, I need some help to finish a natural pool project. Can you tell me the specifications of the perforated pipe you used down in the filter zone? also the pump you used for sucking the clean water of the filter area? I am building an organic pool in Canary Islands and here I can't find those. Thank you and congratulations for the video!

[@DocLindgaard]

Thanks. The perforated pipe is 10cm in diameter (something like this: ornestationmors.dk/en/products/lime-spray--drain/draenslange-sort-50-meter-80-mm-direkte-levering. The pump is a BADU ECO Touch Pro-2.

[@reeyongutube]

Hej Karsten, Beautiful pool! Questions: 1. What is substrate filtration? 2. I want to build a natural pool (I live in Mallorca) and the architect wants to build a 27m2 basement for the machinery! That’s really expensive and I wonder if you need it? How big is the room where your machines are? Thanks! Céline

[@DocLindgaard]

Thanks :-). Substarte filtration is when water flows through a layer of material substrate (in our case small gravel/rocks) where a natural layer of biofilm builds up on the surface of the substarte and cleans the water. In my mind a 27m2 room for pool machinery is massive! Even if you build a conventional cloride cleaned pool. All my technical stuff (pumps, power and so) fits into appro. 2m2.

[@willymakeit1857]

Thanks! We will begin our dig this winter, we have been inspired alot by your ideas and shape for our plans. Your decking is solid and looks very sharp with clean lines, I like to play with concrete which also works better in our climate in lieu of wood. Have you used your UV light filter? Thanks Again for sharing! Looking Great!

[@DocLindgaard]

Thanks. Yes the UV filter runs 24/7 during summer and is turned off during winter. Best of luck with your project. You will not regret having nice swimming water in your garden 🙂

Beautiful pool, did you clean your filtration media?

[@DocLindgaard]

no not yet.

[@lucasthijssen9844]

Hello Karsten, Very nice project and thanks for sharing. I had few questions and hope you could answer them. I'm in Italy, would my climate be ok for a project like yours? Instead of plants do you think that i could use filtration media only, with high surface to volume area? To avoid mosquitoes to breed in your system, what would you suggest? Thanks

[@DocLindgaard]

Yes I sure you could get it to work in Italy as well. Yes you can make a filter with only gravel/filter materiel. The technique is a bit different and is usually done by having a bottom->top side high flow system. And with a high flow system you also prevent mosquitoes from egg laying because they dont do that in flowing water.

[@iconcargarage8179]

Hello, why you choose exact water pump. I am super inspired with your work and i'm trying to work with my pond in the same way. I am now on pump choosing part. What do you think about Jebao 3000 pumps. They use onlu 300-400 Watts in discription what is super cheap in year calculation versus 1,5kw pumps

[@DocLindgaard]

the pump I use is frequency controlled and does not run on full capacity. At the current setting it run on approx. 250 Watts

[@SignatureStagers]

One little comment. I read somewhere that the plant regenration area should be at least the same area / size as the swimming area for the plants to truly do their job and to have crystal clear water. Also a running system woudl help ( a small water feature -maybe waterfall or stream - that keeps the water moving) which would help control algae build up.

[@DocLindgaard]

Thanks 😊. It depends on how you build your system. If it’s solely plant filtration then the area should be minimum half of the swimming area. But if you combine with substrate filtration (flow depended) then you can go to approximately 25% of the swimming area (what I did).

[@SignatureStagers]

@@DocLindgaard Thanks for your reply. And got it ;)

How is the bio film inside? There is present it is slippery and how many times weekly you must need the robot? The robot is clearing also the vertical pools walls?

[@matejferletic7840]

Thank you for sharing! I’m intresting to have more info about the project as which plants did you use, which is the ratio for the plants area comparing to the pool size and if you had some lime on to bottom of the pool due to the plants as happens in the bio lakes or did you manage to have a clean area (if we want to put a light blue instead of green as you used?) where i can find some of those info? Or can you share it directly to me by email? Thank you for your help and congratulations for the project!

@@DocLindgaard in full summer you dont have a problem with algae? Im from Italy, North Italy, and i think that type of pool will be a swamp in hot season

[@reddogdude]

What interesting vids, thanks for posting. Do you think that Denmark’s seasonal cold negatively affects your organic/plants and microbes? Does it take them a while after the cold weather to work optimally? Do you think that a natural system like yours would work better in a warmer place like California or Italy? Thanks again for sharing your info.

[@DocLindgaard]

Thank you 🙂 I think the system works fine in the tempered climate like ours. The filtration efficacy goes down in the winter because of decline in microbes in the filtration area: But so does the algea production. In warmer climates you would have algea production year around.

[@TheGreatHuman]

Have you had any 'visitors' to your pool, as in newts or frogs? Plenty of them here in Ireland. Do you just embrace it or is it simply not a problem where you live?

[@DocLindgaard]

Yes plenty of smaller water creatures finds their way to the pool. No problem because they mainly stay in the filtration area. We just embrace it 🙂

[@jfbaro2]

Sorry for the stupid question, but is it advisable to add those (self-cleaning) spinDown filters as part of the filtration system?

[@DocLindgaard]

Not sure. Because there is no sediment when pumping water from bottom of filtration system.

[@AF-lj1js]

Hello, there. Is it possible for mosquitoes to lay eggs in the filtration pond? Does the pool really need a few filtration systems that aren't meant for microorganisms?

[@DocLindgaard]

There is always flow in the system/pool so no problem with mosquitoes. Regarding the UV-filter, you could probably do without.

Hi, nice work, just wanna know if this kind of pool can be ok in hot area, like 35-40 Degrees Celsius in summer, 5 Degrees in Winter Celsius ? Thanks for your attention.

It should work in that climate

[@RsTHYBO]

Ser bare super lækkert ud Karsten - og fedt du valgte at springe ud i netop denne løsning! Fra din anden video havde du lidt betænkeligheder omkring rørerne om vinteren, hvad har du gjort de andre år med den erfaring?

[@DocLindgaard]

Hej Jonas. Cirkulationen har kørt hele året. Om vinteren dog i 3 timers intervaller og på lavere flow. Pumpestationen ligger 1m under jordniveau og alle rørføringer er i 50-60mm diameter så jeg har godt turde i danske forhold. I vinters og sidste år havde vi nætter med minus 15grader og vedvarende frost over flere da og det gav ingen problemer. Så jeg har ikke de store betænkeligheder på den front længere 🙂.

[@Kinnabari]

Do you have troubles with mosquitos? My only concern for an organic pool is the for the plant part to be a breeding ground for them and idk if filtration and uv could handle that. Looks beautiful nonetheless

[@DocLindgaard]

We have a few small lakes close to our house, so didnt really worry about our little pool regarding mosquitos :-)

[@oliverroberts3436]

Mosquitos shouldn't be a problem as the water is always moving and not stationary or stagnant.

[@Kinnabari]

@@oliverroberts3436 I've got lots of them in my hydroponic system before getting rid of them with screens and bubblers, and I live in the tropic so they're active year-round 😭. Somehow I think the water surface in the plant area will be calmer than the swimming area, is that not the case?

[@__Ryan_]

Maybe get some frogs and lizards if you live in a tropical place. I’m in the southern part of Florida and mosquitoes are a major concern especially with pools of water.

[@smiley2477]

Do the plants in the water attract frogs?

Hej Johnni her fra Århus. Lækkert projekt. vil gerne selv bygge lignede. men hvad koster hele projektet og bygge, og hvad koster det årligt og drive(el og vand osv.)? og hvor i dk har du bygget???

[@DocLindgaard]

Hej Johnni. Har skrevet lidt om udgifter i videobeskrivelsen under video. Vil tro omkring 250k. Alene de 75k gik til træterrassen rundt om poolen, på næsten 100m2. Pumpe, UV-filter og lys bruger nok omkring 6-800 kWh årligt.

Hej Karsten Først må jeg sige flot pool og tusind tak for to rigtig gode videoer. Jeg har to spørgsmål: - Er UV filteret nødvendigt? - Hvem lavede Folie-arbejdet for dig?

[@DocLindgaard]

Tak 😊. Jeg tror ikke uvfilter er absolut nødvendigt men det var ikke den store udgift at indsætte og da jeg ingen erfaring have med projektet valgte jeg at gå lidt med livrem og seler 😊. Folie arbejdet blev bestilt gennem pool firma fra Nykøbing F. Men de sendte en fyr fra Sverige til at udføre det (pensioneret nu) og det ærgrer mig at jeg ikke fandt ham direkte så jeg ikke skulle betale mellemmanden 😊.

[@RapNu]

Hey Karsten, is it posible to use a heatpump on natural pools?

[@booboofinger2595]

I was wondering the same. It would seem that it should be ok however if the return is via a feature such as a waterfall it may loose most of the heat. That shouldn't be an issue with this set up but it would aid efficiency by insulating the 2 return lines, as they run quite a long distance in the shade under the deck thereby robbing heat along the way back to the pool. In my opinion a solar heater would be inline with the natural aspect but would detract from the esthetics of the yard unless it could be located out of sight.

[@DocLindgaard]

Yes, heatpump systems could be added. But I would then suggest using a pool cover during night because I think you would loose a lot of heat during that period.

[@gilbertodiazaraujo5604]

Me puede mandar video desde el inicio del proyecto?

It is bamboo wood decking

[@jeandavidabeelack3990]

Thanks for sharing I am planning to create one too but it would be a smaller one... around 2.8m wide X 9m long. And I am planning to have a 1m wide regeneration zone on 1 side of the pool. Do you think this could work?

[@DocLindgaard]

Thanks :-). With your planned setup the filtration area takes up approx 25% of the total surface area, so I guess it could work fine. Good luck.

[@MardukTheSunGodInsideMe]

Have you ever done any type of bacteria testing? Just curious.

[@flfl3969]

He treats the water with ultraviolet light, so bacteria should not be an issue.

[@flfl3969]

If you installed solar panels you could power a pool heat pump to heat your pool in cold weather.

[@DocLindgaard]

No I have not tested the water. If I got problems with clearity I would probably test for different nutriets instead.

Hi- how long did ur water take to clear up? We just finished building our pool and are in the "cloudy" phase - did yours ever go cloudy at first? hoping it won't last maybe more than a few weeks? Also- did you add any beneficial bacteria to your pool? Thanks!

Thanks. We are quite satisfied with the result so I dont know what I would change. And its a BIG job so I dont think I will do it again :-). Air pumps are not ideal if you need a higher water flow rate.
