Biopools | Chemical-Free Ecological Pools for Your Garden
We create chlorine-free biopools or ecological pools. Pools where plants purify the water in a completely natural way , without the need for chemicals, offering a healthy, sustainable environment in perfect harmony with the landscape.
In biopools, water purification is achieved through an aquatic ecosystem of plants and microorganisms . This natural system creates a clean, healthy water environment that avoids the problems caused by chemicals, such as eye and skin irritation.
This type of pool consists of two distinct but fully integrated parts : a bathing area and a regeneration area , where the water is purified by aquatic plants.
Enjoy the experience of swimming like in a lake, but at home.
What is a Organic pool and why choose one?
A organic pool is basically an ecological pool that functions like a lake. The water is kept clean naturally, without chlorine or chemicals . Plants and biological filters do all the work. The result is clear, healthy, and pleasant water for swimming .
A natural pool: it doesn't irritate your eyes, dry out your skin, or smell like chlorine . Plus, you don't have to buy products every week or spend so much energy on purification systems. It's easier to maintain and more economical in the long run.
It also changes the way it looks in the garden. A conventional pool often disrupts the landscape. A organic pool blends into the surroundings, with stone, wood, and vegetation . It doesn't look like a concrete structure; it feels like part of nature.
The important thing is that you enjoy a clean and safe swim , while your eco-friendly pool helps protect the environment instead of damaging it. That's why more and more people are choosing this system: for health, aesthetics, and sustainability.

What is the maintenance of a Biopool?
Maintaining a biopool isn't complicated , but it does require consistency and some care. There's no chlorine or chemicals doing the work alone: here , nature itself keeps the water in balance, and we accompany the process with a few basic tasks .
Cleaning the water and bottom
Leaves, insects, and dirt often fall off over time. It's normal to use a manual pool cleaner, a robotic pool cleaner, or an automatic system , depending on how convenient you want it to be. The frequency depends on how demanding you are about water clarity.
Filtration system care
Biological filters work independently ; they hardly require manual cleaning. What 's important is to ensure that the low-consumption pump and water circulation are working properly , as the stability of the entire system depends on this.
Pruning and fertilizing plants
The plants in the regeneration zone perform a key function: they purify water. They should be pruned annually , and in spring, it's recommended to fertilize them so they grow healthy and do their job well. It's a simple but necessary maintenance.
Periodic review
From time to time, it's worth checking that the plants aren't overgrowing and that the pump is responding properly . If this isn't done, algae can appear or the water may become cloudy. Regular maintenance can easily maintain the balance.
Additional tips
-
Avoid detergents when cleaning the edges: they alter the water and damage the ecosystem.
-
Keep an eye on the pH, which should be between 7.2 and 7.8, to keep the water clear and healthy.
-
Keep in mind that climate, location, and the quality of the water used to fill the plant also influence maintenance: the more adapted the plants are to their environment, the easier they will be to care for.

Benefits of swimming in a biopool
The experience of swimming in a biopool: The greatest benefit
The most valuable thing about a biopool is how you feel when you swim . It's not like stepping into a conventional pool; it's something different: here, the water is alive, chlorine-free, and chemical-free , and the sensation is one of merging with nature. You swim like you're in a clean lake, with calm and well-being.
-
You can open your eyes underwater : without irritation, without redness and with the freedom to look underwater as if it were a crystal-clear river.
-
It doesn't sting your skin : the water doesn't dry out or cause discomfort, it's soft and pleasant with every bath.
-
It does not harm the skin : since it does not contain aggressive chemicals, it is perfect for people with sensitive skin or allergy problems.
-
You don't have to shower when you get out : the water doesn't leave any smell or sticky feeling, just freshness and lightness.
For those with atopic skin, allergies, or who simply want to take care of themselves in a more conscious way, this experience goes from being an ordinary bath to becoming a necessity .
Design and construction of custom biopools
Every garden and every client is different. That's why we don't make eco-friendly pools the same .
First, we look at the space, listen to what you want, and then come up with a design that fits everything.
We work with EPDM geomembranes, stone, wood, and plants that adapt well to the climate . This creates durable, easy-to-maintain pools that look like a natural part of their surroundings.
We take care of everything: design, construction, and installation . In the end, you'll have a biopool ready to enjoy, hassle-free.

Differences between biopools, natural pools, naturalized pools, ecological pools, and high-tech pools
-
Organic pool : A pool that purifies water using biofiltration and aquatic plants, without chlorine. It functions as an ecosystem.
-
Naturalized pool : A conventional pool that is transformed into a biopool, adding biological filters and a regeneration area.
-
Natural pool : An ambiguous term. It can refer to biopools, but also to pools with a natural aesthetic (rocks, waterfalls) that still use chlorine.
-
Ecological pool : Trade name, synonymous with biopool, which highlights sustainability and environmental respect.
-
High-tech pool treatment : Pools that don't use plants but instead use advanced purification systems (ionizers, ozone, UV lamps, state-of-the-art filters). The water is clean and chlorine-free, with less need for visual maintenance.

Where are the best biopool installers?

Origin of biopools, or natural pools
The origin of biopools, or natural pools , dates back to landscape design practices and aquatic constructions in ancient cultures, although their modern development began to take shape in Europe, especially in Austria and Germany, in the 1980s.
These first biopools were created as a response to growing concerns about the use of chemicals in traditional pool water treatment and their environmental impact .
The concept was inspired by aquatic ecosystems, where plants and microorganisms work together to naturally purify water . The idea was applied in small leisure facilities and eventually became popular in Europe, being adopted in numerous residential and public projects.
Today, biopools can be found all over the world, from private gardens to recreational facilities in parks . This innovative approach not only promotes human well-being but also respects and preserves the environment, while offering an aesthetically pleasing and sustainable alternative for enjoying the water.
