What about snakes ???? 🐍

@@horseshill Natural pools and ponds can attract wildlife, including snakes, depending on various factors such as geographic location, surrounding habitat, and the presence of suitable food sources and shelter. While natural pools and ponds may attract snakes, it's essential to remember that snakes are generally shy and prefer to avoid human contact. Taking precautions such as keeping the area around the pool clear of debris, maintaining a well-groomed landscape, and educating yourself about local snake species can help minimize encounters with snakes and create a safe and enjoyable outdoor environment. Additionally, if you live in an area with venomous snakes, it's crucial to be aware of their presence and take appropriate precautions to reduce the risk of snake bites. Remember though.

It's crucial to understand the risks of parasites in tropical natural pools. Two primary concerns are Naegleria fowleri, or "brain-eating amoeba," and schistosomiasis (bilharzia), both found in warm freshwater. Naegleria fowleri can cause severe brain infections but is exceedingly rare, with a reported risk of 1 in 142 million. Schistosomiasis is transmitted by parasitic worms facilitated by freshwater snails, particularly in warm climates where water temperatures exceed 27°C. The disease can be a concern in pools filled with water from sources where bilharzia is endemic. To mitigate these risks, if converting an existing pool, ensure it includes a sand filter, ideally upgraded with glass filtration medium. Regular circulation of the pool's volume, combined with a UV filter, significantly reduces the chances of parasitic infections. Additionally, biweekly treatments with 30% Hydrogen Peroxide can virtually eliminate any risk, as it destroys parasites while oxygenating the water. Though some beneficial microorganisms may be lost, most will remain in the wetland area.

@@leafandstone.naturalpools thank you, I appreciate the info. I'm very very interested in building one of these from scratch. These are almost unheard of, everyone has a chlorine pool which I hate but I admit that when the heat hits 110 or more, then a pool is tempting. Your work is awesome!

Would definitely love to know more about the maintenance aspect like this too

When it comes to cleaning, the walls of a natural pool generally don’t require much scrubbing. The biofilm that forms on the walls is part of the natural ecosystem and helps maintain water quality. However, you might occasionally need to gently brush away any algae buildup, especially in areas with less water circulation. Using sunscreens or lotions can introduce oils and chemicals into the water, which might affect water quality. It’s best to use eco-friendly, biodegradable products if you’re swimming in a natural pool. This helps minimize any negative impact on the plants and microorganisms that keep the water clean. If a child has an accident in the pool, the natural filtration system can handle small amounts of organic matter, but it’s a good idea to remove any solids promptly and ensure the water is circulating well. In cases of significant contamination, you might want to temporarily increase water circulation and filtration to help restore balance quickly. Additionally, it’s crucial to ensure that the water circulation system, including pumps and filters, is working correctly. Cleaning and inspecting these components regularly will maintain efficient water flow and filtration. Monitoring the water level, especially during dry spells or heavy rainfall, is another important task. Adjusting the water level as needed helps maintain the balance between the swimming and regeneration zones. Occasionally, you may need to remove sediment buildup from the bottom of the pool. This helps prevent the regeneration zone from becoming too clogged and maintains its filtering efficiency. If you notice excessive algae growth, consider adding UV sterilizers or natural algae controls, like barley straw, to keep it in check. Overall, natural pools are designed to be low-maintenance, relying on biological processes to keep the water clean. With a bit of regular upkeep and mindful use, you can enjoy a beautiful and eco-friendly swimming experience.

Absolutely, future videos and workshops will definitely cover strategies for natural pools in different climates, including hot areas like Phoenix. Managing water temperatures during the summer can be challenging, but there are several techniques and designs that can help keep your natural pool at a safe and comfortable temperature.

100ppm 35% H2O2 peroxide once a fortnight or weekly in hotter climates! also adds oxygen to the plants ;-)

Hi Habibi, interesting question. It woudn't be a problem though. Deep is actually good as the water at the bottom doesn't see much sunlight. You could very easily slowly circulate water from the bottom to the top. All natural pools do this. That is... they all circulate right through the whole system.

Winterizing a natural pool is essential for maintaining its health and beauty, especially in colder climates. To winterize your natural pool, start by removing any debris like leaves and twigs to prevent the buildup of organic matter. Trim back the aquatic plants in the regeneration zone to reduce decaying plant material over the winter. Adjust the water level if needed to protect the pool structure from freeze-thaw cycles, and disconnect and store any equipment that could be damaged by freezing temperatures. Some people also choose to cover their pool with a net or tarp to keep out debris and minimize maintenance in the spring. As for the plants, they typically go dormant during the winter rather than dying off completely. Most plants used in natural pools are perennials, meaning they will regrow from their root systems when temperatures rise in the spring. These hardy species are adapted to survive cold temperatures and will start growing again once the weather warms up. If annual plants are used, they will need to be replanted each year. In the spring, you'll need to clean up any remaining dead plant material and debris, reinstall and inspect any equipment that was removed for winter, and monitor the regeneration zone for new growth. By following these steps, you can ensure that your natural pool remains healthy and beautiful year-round, with the aquatic plants playing a vital role in maintaining water quality as they regenerate each spring.

@@leafandstone.naturalpools Very interesting. Thank you for the thoughtful reply.

@@Ozjockey111 Yup the H202 (peroxide) is a great method. It can also clear string algae and the plants don't mind it at all. A UV filter is also going to kill any pathogens floating in the water body.

Yes, it is very much possible. They are actually beneficial BUT one has to be careful. I generally advise putting small goldfish or tilapia in the pool and then not feeding them or feeding them very little. If there is enough of an area for them to scavenge they are happy and beneficial. When you feed them you are introducing nutrients which can lead to Algae problems.

It's great to hear you're considering investing in a natural pool! Regarding your concerns about mosquitoes and other bugs, natural pools are actually designed to prevent mosquito breeding. The key is maintaining constant water movement and sufficient oxygen levels, which discourage mosquitoes, as they prefer stagnant water for breeding. Additionally, natural predators like backswimmers and dragonfly larvae are beneficial and help control the mosquito population by feeding on their larvae. If you're still concerned, incorporating design elements like strategic plant placement and water features that enhance water circulation can further minimize the presence of unwanted bugs. Rest assured, a well-designed natural pool provides a habitat for beneficial wildlife while keeping the less desirable critters at bay.

@@leafandstone.naturalpools i appreciate you so much for your response! What you described makes so much sense. Thank you.

Indeed they do. Water needs to be circulated with some form of pump. There are examples of pools called schwimmteich that use thermal circulation from sunlight to circulate the water but they are only proven to work only in cool climates.

You can absolutely include UV sterilizers, which are particularly beneficial in very warm climates. UV sterilizers help control pathogens and maintain water quality by using ultraviolet light to disinfect the water. This is especially important in warmer climates where higher temperatures can encourage the growth of harmful microorganisms. In cooler, temperate climates, the wetland area and natural processes in a well-designed natural pool are typically sufficient to keep pathogens at bay. The plants and beneficial bacteria in the regeneration zone work together to filter and purify the water, ensuring it remains clean and safe for swimming without the need for additional sterilization methods. By incorporating UV sterilizers where needed, you can enhance the natural filtration system and ensure optimal water quality regardless of the climate.

If you plant sweetgrass there you will be safe from them☀️

The problem is a natural pool works by being an incredibly low nutrient system which is the opposite of an aquaponics system. they are not mutually compatible.

Hi There. I currently have an online course for doing natural pool conversions with a floating system and for a gravel wetland new build I do one-on-one consultation and plans etc. leafandstone.co.za/natural-pool-consultations

A natural pool costs less to run than a conventional pool. The energy consumption is anywhere from 50% - 25% less (depending on the design of the pool). For a natural pool we typically use a 75W running 16hrs a day (1200W p/day). A conventional pool will use a 700w pump for 4hrs a day (2800W p/day). There is also no need for the cost of chlorine or other chemicals as well which can easily amount to $50 per month.

@@leafandstone.naturalpools Thank you!! It'll be a interesting topic for a video to go deeper into this comparison, including construction, mantainance and even demolition. As an architect, I'd appreciate the insight

Yes, it's possible to create a man-made pool that mimics the composition of ocean water without using a salt chlorinator. This type of pool is often referred to as a "saltwater pool". You would need to add salt to the water to achieve the desired salinity level, which is typically around 35,000 parts per million (ppm), similar to seawater. In terms of operation, you could still use a filtration system such as a bead filter in a saltwater pool. However, you would need to ensure that the materials used in the filtration system are compatible with saltwater, as saltwater can be corrosive to certain metals and materials over time. Choosing corrosion-resistant materials like stainless steel or PVC for the filtration system would be advisable. Scaling can be an issue in saltwater pools, just as it can be in traditional chlorinated pools. To prevent scaling, it's important to monitor and maintain the water chemistry, including pH and calcium hardness levels. Regularly cleaning the pool surfaces and equipment can also help prevent scaling buildup. I don't know anyone doing this in the states tough.

Hi there, yes, absolutely. leafandstone.co.za/natural-pool-consultations take a look at that link. I will be uploading more videos on an ongoing basis but I do offer one on one consultation as well.

It is important to note that there is always a risk of parasites when having a natural pool in the tropics. This is ultimately a decision and a risk you will have to be responsible for once weighing all the factors up. Lets quickly look at the 2 main concerns. Naegleria fowleri, also known as the "brain-eating amoeba," is a rare but deadly single-celled organism found in warm freshwater environments. It can cause a severe brain infection in humans when contaminated water enters the nasal passages. Even if the water temperature exceeds 27°C, the risk of contracting Naegleria fowleri remains incredibly low. How low exactly? Reported statistics indicate a risk of 1 in 142 million. Just pause and consider that for a moment. You could swim in water containing detectable levels of Naegleria fowleri twice a day for 50 years, and still, the odds of infection would be 1 in 4000. Natural pools in the tropics, particularly those located in regions where schistosomiasis (shuh·stow·suh·mai·uh·suhs) (bilharzia) is endemic, could potentially pose a risk of transmitting the disease if not properly managed and maintained. Bilharzia is a waterborne disease caused by parasitic worms that can infect humans through contact with contaminated freshwater sources. The bilharzia parasites have an intermediate host: freshwater snails. These snails are necessary for the parasites' life cycle. If your natural pool contains these snails, the risk of transmission increases. These parasites, which cause bilharzia, thrive in warm and tropical climates and water temperatures above 27°C (80.6°F) provide an environment conducive to the growth and transmission of bilharzia. The source of water for natural pools is important. If the pool is filled with water from a local lake, river, or pond where bilharzia is present, there is a risk of contamination. Parasite Prevention: If you are converting an existing pool with a floating wetland you should already have a sand filter. If you keep this running to circulate the entire volume of the pool everyday and you include a UV filter after this, then the chances of Bilhazia, brain eating amoeba and other parasites becomes very small. You will also want to regularly brush the pool walls and run a pool suction cleaner everyday to ensure you dont have water snails which can act as hosts for Bilhazia. You need to also ensure that water fowl don’t poo in the pool as excrement often carries pathogens.

🤌🏻👏🏻👏🏻👏🏻👏🏻👏🏻 I assume that your answer will also fit well for the brazilian 🇧🇷 tropic regions like north and northeast. I think the biggest risk will be aedes aegypti here. Thanks a lot, your content is great and well produced.

Yes, the same would apply :)@@kevind-neri

No, I built my natural pool 4years ago and haven't seen a single mosquito larva. I believe the slow but continuous circulation is the reason.@@kevind-neri

I imagine the same applies to the beaches of Mexico, where the climate is hot…. Thanks 😊

Natural pools can be heated but to a maximum of 27C. Having a pool heater generally means one has to keep the pool covered otherwise you lose 70% of the heat. This is absolutely possible but can limit your design choices. It is also advisable to have UV sterilizers as part of the system if one is keeping the temperature high.

Just gotta trust the process of a balanced ecosystem I guess🤷🏽‍♂️

See other comments , this is answered

In regards to Naegleria fowleri and other water borne pathogens. Natural pools are safer than fresh water bodies found in nature (lakes, rivers etc) as the water is constantly being circulated through a highly concentrated natural filter. However, this is provided that that A) The water temperature does not exceed 27C and that B) there are not loads of people swimming in the water all the time. I would not advocate a natural swimming pool in a public area for this reason. A private pool in a residence has an insignificant risk in regards to fecal coliforms etc. Even if the water was warmer than 27C, the risk of getting a Naegleria fowleri is still so low. How low? A reported a risk of 1 in 142 million. So just think about that for a second. You could swim in water with detectable levels of Naegleria fowleri twice a day for 50 years and still, the odds of getting infected would be 1 in 4000. If you are happy to swim in mountain stream or pond, where you live, then you should not think twice about swimming in a natural pool as the chances of infection would be less.

@leafandstone.naturalpools ah ok! That is one of the 2 things that worried me about these natural pools, thank you

I wonder if UV light is harmful to "good" microorganisms of the pool

@@anonimo5912 The UV light will kill beneficial bacteria in the water BUT remember this is only those that are free floating in the water. The majority of the beneficial bacteria live in biofilm that is stuck to gravel and roots in the wetland. So the UV just ensures that the water where you swim is free of pathogens.

@leafandstone.naturalpools thanks for the information, it seems like you really know about this

Hi Anne. Are you speaking from direct experience? A natural pool (if well designed and constructed) is no more maintenance than a normal chlorine pool. There are many badly built natural pools, which are a nightmare to maintain, this is sadly because, over the years, there has been very poor information on how to build them. Which I intend to change. More importantly, almost all the people I have made pools for who have built their own using my guidance and courses comment that the maintenance is actually enjoyable. Like tending to a garden.

@@leafandstone.naturalpools correct-amundo, you will get frogs swimming in your pools though but they love the mosquitos also ;-) we find that most people love the froggies...

False. These pools require much less maintenance than a conventional pool

There is no maintenance for natural swimming pool, the nature does it for you

meh not by much

You can build natural pools for low cost and high cost. If you look at the rest of my content much of it is about empowering people to create their own natural pools for very low cost.

The exception is if you live in an area that is devoid of much life, such as arid areas or a desert. Your natural pool would then be an oasis for wildlife including snakes. If being in nature, swimming in wild spaces is not your thing due to fear of snakes and bugs then best to just stay in doors ;)

circulation for to clean the water is an important part of such structure's filtration.

It has as much mechanical filtration as you want to include or not include. Skimmers, filters, circulation - these all functions the same as a conventional pool. Mechanical means like a sieve to remove leaves, dust etc.

It's not actually that cheap if you add up the monthly cost. As for being eco-friendly...hmmm, I will have to differ!

How much is it in your country? Here in europe, i can buy 3litres of chlorine 5% solution for like 2USD(two, not twenty). I think there were studies that even 1:100 solution of 5% kills everything in minutes. 1litre is basically enough for 1 family/year of household cleaning. Sounds cheap to me. When used its changed to free Cl- and NaCl i think, which both are not dangerous if used properly@@leafandstone.naturalpools

It's expensive and terrible for the environment!

@@PatrickCole-md9bu I pay 1usd for yearly use for whole house. Its just 5% solution of Sodium hypochlorite with water, after usage its converted into NaCl(kitchen salt), and free chlorine gas.

Would you consume a bottle of chlorine? If so, what would be the effects? You sound like one of those idiots from Monsanto claiming that said pesticides are safe, but refuse to drink a glass. They refer to Bleaching of the reefs as Bleaching, because it's bad. It's reference to something terrible and in most cases irreversible!

Hi Gary. I love Mr David Pagan Butler but he is certainly not the pioneer of the natural pool. :) The first recorded man-made natural pool utilizing a biofilter or wetland to clean the water is a bit challenging to pinpoint with absolute certainty due to the limited historical documentation on such innovations. However, one significant early example is the modern recreation of natural swimming pools, known as "swimming ponds," which gained popularity in Europe during the late 20th century. In the early 1980s, Austrian landscape architects and environmentalists such as Günther Künstle and Werner Gamerith pioneered the concept of natural swimming pools that mimic freshwater ecosystems. These swimming ponds utilize aquatic plants, gravel beds, and microorganisms to filter and purify the water, eliminating the need for traditional chemical treatments like chlorine. One of the earliest documented examples of a natural swimming pool is the "Schwimmteich" (literally "swimming pond" in German) built in 1985 in the village of Hechtel in Belgium. This project was a collaboration between landscape architect Bruno Wallraf and biologist Frank Schüler. The Schwimmteich served as an inspiration for further developments in natural swimming pool technology across Europe. These early experiments with biofiltration systems in swimming ponds laid the groundwork for the modern natural swimming pool movement, which continues to evolve and gain popularity worldwide. Today, natural swimming pools are appreciated not only for their ecological benefits but also for their aesthetic appeal and low maintenance requirements.
