Nowadays, the design of a biological pool can be very similar to a conventional pool. I does not have to remind you on a pond of plants.

In English-speaking countries there is a special expression for this type of biological pool: natural pool or natural swimming pool.

The shape can be even very architectural, a rectangular basin, for example. The materials can be different, a slate tile covering, as shown in the photo. The finishes can be the same as in a conventional pool, also overflowing on all four sides of the basin.

What is different is the treatment system? It is 100% natural and works with a biological filter where biofilm living beings clean up impurities in water, bacteria and microalgae.

What matters is the result. A clear and very transparent water, 100% treated by biological means and free of any chemicals.
