Hi David, love your videos and pool designs. One suggestion on the hole drilling, when the hole cutter gets the bite on the plastic pipe, stop the drill and put it in reverse. It'll give you a cleaner edge and there's less chance of the plastic breaking. Keep up the great work. 👍
Another wonderful video. Your casual absorption of momentary false steps makes me ready for any project that catches my fancy. Thanks for your great attitude.
I really enjoy your videos. I'm converting a concrete pool to a natural "kinda" pond and I'm using air. My 80 liter pump at 700 watts for lunch all day and night long. I've discovered building a drain field under six feet of water is a bit more challenging than a dry fit and then submerging. SCUBA along with 30 pounds of weights is part of the fun. Thanks for the fun and motivation David,
David I currently Live on 5acres and this is something we've talked about doing for a while now, thank you for your explanation and i hope you continue to make more videos. Your such a Human being.
Lol "...I really wish there was some other way to do this...Never has DIY been so hard..." love the info on the pump though super helpful thank you for your sacrifice!💀😂👍
My summer project is making a fresh water pond. It's good insurance if the power went out for a while. You have inspired me to do it. When I finish I think it would be a good idea to added fake plastic lillies to the surface of the water to keep the algae from spreading.
I might suggest a spa blower. Much more efficient that the typical piston compressor. I have had them work to 4' depth maybe deeper I have just not have the need.
Thank you for sharing this incredible information. Any recommendation on size/strength/number of pumps for a "standard" size pool with 4 of these Enhanced Bubble Pumps setup?
Your drill is plenty strong to drill through the cap, it was not because you needed a corded drill that it was stopping. Turn your chuck and it will not stall out.
Hello david. Thank you very much for the excellent explanation. And I ask you a question ... what size aerator or air pump is needed for a pool of approximately 30,000 liters. It measures 2 by 11 meters. by 1.7 deep. I appreciate your information.
Hello sir. What type of air compressor are you recommending? PSI? I am putting materials together to start a large swim pond on my 30 acres here in Alabama, USA. Love this idea with the bubble pumps
Hello David, thank you for all your videos! Is there any way to calculate what pump / air flow will I need for a pond with 80 square meters of swimming area and same footage for filtration zone?
Could you make a video on just the basics of the way pumps work in general for someone that has no experience or understanding of pumps. I see that the bog area of your poolsHas piping all the way around it is that taking water from the pool and putting it into the planted zone or from the planted zone into the pool? Breaking all that down for someone that is kind of dumb about these things would be really helpful.
@@738rh I am struggling too with designing the pump installation water flow and filtering. Impossible to find well explained videos and drawings without falling into websites that want to sell you complicated systems.
@@738rh for you it is but for people that want to built their own pool without experience ir is a challenge just to design a basic system that works to circulate the water and inject air in the right places
really nice idea, the like the hole concept of the natural swimming pond. On a different note, this video shows that teaching is a calling not something anyone can or should do, you may know your stuff inside out, backwards and forwards but if you can't teach it, get someone else to do it for you. . . . but nice video anyways ;P
Hi David. Have you found the increased draw through the planted zone is necessary due to root development over time obstructing flow through planted bed? Do you feel at this stage that you have reached 'steady state' development of roots/obstruction or that you will need to periodically excavate parts of planted zone to remove this extra sediment? Or have you revised how many recirculating loops you install in future builds? regards, Brian
Easy fix for root development..... Pump or siphon the water level down below the gravel planted .... After harvesting some plants for the restart, let it all die. Then start over. Probably....an every 3 year project that takes a month in the hottest month.
Hey everyone, I have made several air pumps using David’s design and dropping the air stone down the middle. This is so simple that I have just knocked these together. But has anyone compared the flow rate of this with the Czech design or the ones where they run the air external to the large outer pipe then attach a collar and drill small holes in the inner pipe. That would be a great video as there seems to be a lot of guess work in this.
@@darkdeepfire do you mean just putting an air stone down a 75mm pipe on its own? The bigger pipe just acts like a mini reservoir bringing water from another tank or area of the pond.
Thanks for another informative video. Do all airstones need to be at the same depth? If one is much deeper (+1m) than the others on the same air circuit will any air go to it or will it mostly exit the shallower air stones that offer less resistance?
I understand the aeration stone moves the water which then pulls in more water, but wouldn't a pump be a better idea for moving large volumes of water? Maybe have it cascade in a water fall for aeration? I'm a complete beginner.
I'm in the process of planning to construct one of your Organic swimming pools on southern Portugal, I have your book and watched your film. My question is around considering the hot climate there, would this method also help to reduce the heat exchange of the Regeneration and swimming zones? We are obviously already making the pool deeper and without insulation, if you have any other recommendations to reduce the heating of water, that would be great.
I like your system a lot and your films ;) are hugely helpful. One question though. How do plants do with all this oxygen? Don’t they live of Carbon dioxide?
Hello I have seen similar concepts for Aquaponic systems. But this concept was a pleasant surprise. But I still wonder about 1 problem in particular. What about the mosquito population around thous systems? Is the water flow strong enough to prevent a massive increase or are there other solutions?
I am planning a natural pool for my backyard but am planning to keep the water temperature between 70 and 85 degrees Fahrenheit (21-30 celsius) year round, so much warmer tropical pond. To keep algae growth down would these enhanced bubble pumps be enough or should I incorporate a deeper, larger filter bed? Or both?
Trying to finalize plans for a pool. Air lift pump has me thinking. Why not have a pipe plumbed into the deepest part of the pool. Have the water column dump out into a container in the regeneration zone that is just inches above the waterline. Large diameter flexible non-perforated drainage lines run from the sides or bottom of this container and feed a network of perforated drainage pipe at the bottom of the gravel bed. In this way, detritus is brought up from the bottom of the pool where it can be filtered in the container, and gravity will cause the water to flow through the tubes to the bottom of the gravel bed. The water then percolates back up through the filter bed, and the process begins again.
Great videos. Just a quick question. Do you find you get a build up of solids in the bottom of the tube? I would have thought that as the water changes direction that the solids would drop out of suspension.
Hi David. How can I get the intake for my airlift to suck the solids from the bottom of my 2m deep pond that slopes down? and pump them into my filter system. Thank you
Hey David, could you please show us a comparison of the flow rate between the 1m and 2m depths? I'd like to see it with the full 2m of pipe. Great video as always!
ya blew it the more bubbles are in the tube at any one time before it reaches the surface, the bigger the volume of water is able to be displaced, placing the waterstone lover down increases the time that the airstone has to produce bubbles before the first bubbles reach the surface, increasing the number of bubbles in the tube at any given time, increasing the water displacement and flow rate
you will need to find the best most efficient combination of depth and pressure your self , as depth will decrease the pressure of air too , so its not that increasing depth will always give u more flow but at some point the efficiency will begin to decrease , there u need to install it depending on ur air pump power. but im not sure if it applies same for the chambered version .
I am wondering about calculating the flow rate of the water leaving the planted zone. I've watched all your videos, including where you explained how different sized pipe will result in different flow rates, but that didn't address the flow rate of the water passing thru the planted zone.
It does not matter as your pipes are always submerged so what leaves the air pipes, gets balanced through the regeneration zone, just displacement of water
Well, not entirely true. My experiments with submerged pump showed a negative pressure appearing at the bottom of the regeneration zone and reducing the momentum of water - flow rate. I wonder. How does that affect the bubble pump ? Emma made a really good question here.
Hi David, If the filtered water is being reintroduced at, almost, surface level around the perimeter of the swimming zone and being drawn back into the regeneration zone, how does the water at the deepest part of 2-3m in the swimming zone get circulated? I need a deep pool of say 3m to cope with the heat in Thailand, and am concerned the deepest volume of water will not be getting circulated and filtered.
David uses this example for people with limited space and pump power, so in your situation you would play with pipe diameter, pump liters per minute (at your depth) and amount of air stones, but you would not need to encase a pipe within another pipe, just have your pipe close to the bottom of the pool
@@christurner3857 the deeper you go, the thicker pipe will give you more flow, stay with a minimum of 60L/min per stone. Pvc is so cheap so decide on what you want, flow, pressure or effect
Hi David, Isn`t it a problem, if we have more oxygen in the water which will eventualy reduce the CO2 concentration and can influence the plant growth? Have you come across such situations?
hi! i'm not an expert on natural pools, as i'm just starting to design one. But i have a marine sciences degree, and as far as i know, the kinds of plants that are used in these pools get the CO2 from the air, so the gas ccomposition from the water is not really important. although, it is important for the algae, but the water in the pool will most likely remain in balance with the air, so as long as the air has CO2 in it, your plants and algaes will be fine.
Na mate the air pump works buy displacing water out to the pipe making the water in the pipe weigh less than the water out of the pipe the water out of the pipe enters the pipe because of this and pushes the l8ghter airated water out the top what you are doing will make the pump work harder for every liter of water it pumps in this may go un noticed if you have a strong air pump that you weren't pushing to its full abilities in the firstplace( and not running itat its best ability) but if youare already running thepumpat its best ability you wont get much gains because of the increased pressure uneed to push itdown theincreased distance You can get thesame effect buy jus keeping the air stone at the same depth and just spiraling the pipe to the surface the air will displace the same increased amount of water without working the pump harder What youcan do
Thanks for your videos I just need to know what pipe to put inside the plated zone and if EPDM is the best choice for the liner. I live in Lakeland FL thanks
What is the advantage to using compressed air? Using water pumps will move the water much more efficiently. A series of shallow waterfalls at the surface will aerate the water just was well, one might think.
I think cost and maintenance? Thats what ive been gathering. u dont have to worry about sand or debris getting stuck in the air stones like you do with pumps moving the water not to mention if u have really hard water like we do here it builds up calcium in pumps.
@@brentpal Good points! During the month since I posted that question I've had a chance to research more and I find that air can lift a column of water significantly well to do a modest waterfall. Considering the aeration already being performed in the water column, it does seem a good way to go. Only downside I see is compressor noise. A submerged pump is silent. I guess if you have the luxury of locating the compressor adjacent to a central A/C unit, very little is compromised.
Stick with the original pipe but just go down before you go up. U shape with only one leg containing the air bubbles pulling the water out. This should be less complex and maintain the same flow expected from the pipe diameter and depth.
Excited to build a pond in the next couple years. could you please list some examples of good air lift pumps that would work for this application? Thanks from West coast of Canada. Appreciate your videos!
One suggestion...do not cap the bottom of the 4" pipe so you circulate the stagnant deep water water plus oxygenate it (an algae killer). Great work though!!!! thanks.
if im not wrong , the cap keeps pressure off the chamber inorder for pump to work at its optimum .so the pump is only baring the pressure of T height as thats where water is coming in from
@@TristanMorrow Good point! You will need a removable bottom cap to clean the sediments as part of your periodic maintenance. It shouldn't be difficult to implement and to service.
How can I contact you? I am interested in your knowledge and expertise as I am planning on building an organic pool close to Barcelona (Catalonia) .... can you reach me? please. Thanks!
Question, does it make sense to place the bubble pump further away from the planted zone? I'm thinking it may function in the current design as a divider that causes a rotation in the swimming zone, preventing a chunk of the swimming zone to never make it to the planted zone.
My research into air rings in water says that you mainly need to release the air 9ft down. I always imagine incorporating this into one of your pools so that rings left the top of the pipes. That requires 2.7m depth however. Do these things require planning permission?
Depends on local council regs on their definition of a swimming pool vs fishpond/ornamental water feature. My friend was given a whole stack of regulations when she enquired about installing a chlorinated swimming pool however to install a fishpond the only regs were distances from property boundaries and easements. She is going to use this loophole to make an organic swimming pool. She has categorised it to local laws as a lily pond/water feature..( there are no laws stating you can't swim in your water feature)
Wait a minute! You made a quite a lot of fuss about how wonderfully gentle the original pumps were and now suddenly they're not strong enough? So where's the truth? There's not much help in the inventor being confused himself.
Interesting... I guess... Is it really so hard for everybody to stop just winging all of their videos? I still don't really understand your method or why it works.
NEED ADVISE ON SIZE OF AIR PUMP.... We've excavated our natural pool and ready to put the liner in next week..... JUST DON'T KNOW WHAT SIZE AIR PUMP TO GET I only need 4 air bubblers.

@@immortalayarna I Just built a massive 63,000 litre natural pool.. Using a Resun LP-100 (140 lpm) Septic Air Pump... Works amazing water insanely clear 3 airstones & 3 air lift pumps
@@thebushnells Amazing,Thanx alot Nick extremely helpful info, i hope u might hve both the time and chance to show your pool setup on youtube. but please clarify, you used 3 airlift pumps(140 lpm capacity) with a single air stone connected to each for your 63,000 litre pool ,right?
David, I've always valued your videos but you need to move forward with that one. This is not effective way of either aeration neither filtration through circulation. I think the best way now is "microbubble" or even "nanobubble". With a low watt you can heavely oxyginate water, and also create a very nice streap for cyrculation. That aproach might be much more effective.
