Waterfowl eat frogs, frogs eat insects, and insects eat fungi. This is how the lake and pond food chain works, and this is how the filtration and water renewal system of biological pools works.

Unlike traditional swimming pools that require high construction costs and costly maintenance, biological pools offer a more economical and sustainable solution for the environment. In addition to dispensing with the use of chemicals to maintain water quality, the materials used in their construction are often natural elements already in the surroundings.
Visually similar to natural lakes, biological pools are an attraction for local fauna and flora, making them a privileged spot for nature observation. Divided into two areas: the bath area and a biological water purification zone, their assembly results in a healthy, balanced and dynamic ecosystem that invites to delve into its charms, without fear of opening the eyes because of the chlorine.

Naturally, building a biological pool always involves some human technology. The application of an insulation canvas throughout the interior of the pool is essential not only to prevent water from flowing through the soil, but also to preserve the natural heating of the water by the sun. For the water circulation system, the use of solar panels is undoubtedly the best solution for those who want to spare the environment, and save in the electricity bill.
To ensure greater safety when accessing the pool, the use of a deck system are still an option to take into account. In everything similar to natural wood, this type of pavement stands out for its durability, and for the harmonious and discreet way it is integrated into the natural spaces, preserving its primordial beauty.

Whether for the fun they provide or the tranquility they convey, the fact is that biological pools keep on winning fans all around the world. To better understand why, and perhaps inspire you, we’ll show you some of the best examples.
Some families are choosing to build natural pools with elements of nature and that look like small lakes. The process is based on digging a hole that will be the actual pool area, with about 1.70 meters, insulate with canvas to create walls , by using sandbags.

In addition to the pool areas, banks are created naturally, with all the typical pond fauna and flora. This creates a totally sustainable ecosystem, where the nature cycle takes care of maintaining the pool.
The plants and algae that later grow oxygenate the water and the animals also contribute to keep the pool balanced: so the food chain gets started. That is, all the natural elements come together to create a habitat where people and nature are in harmony.

In terms of man-made elements, so to speak, there is only one insulation of the tank zone to help preserve the solar water heating, silent handmade filter and a water circulation system powered by a set of solar panels.
The creator of this pool, David Pagan, whom you can see in the video, says that the cost of doing such a work is ‘a fraction’ of what would have to be spent to have a conventional swimming pool, like the whole system of water renovation, pumping and maintenance.
