Biopools

A biopool is the ideal solution for anyone who wants a pool with a sleek design and crystal-clear water that is free of chlorine and other chemicals.

The swimming pond and its advantages

A pond adds a touch of idyllic tranquility to every garden: the calming waves, the sound of the gentle whirl, the aquatic plants and the sparkling reflections of the sun... But what if we told you that you can experience this and also be able to splash around in the water? The swimming pond combines these two great advantages, as it allows you to swim in a natural pond that blends in perfectly with the design of your outdoor space and whose water treatment is chemical-free.

Clear and clean water in a natural way

Thanks to its water filtration system without the use of chemicals or antiseptic UV light, the swimming pond guarantees you crystal clear and clean water. Replacing chlorine with a biological treatment base is the secret of Pool For Nature. Gillen also takes care of the maintenance so that you can enjoy your swimming pond in peace.

  1. Offers the same bathing experience as at a lake

Biopool: Swimming pool look with biological water purification

A biopool is the ideal solution for anyone who wants a pool with crystal-clear water and a sophisticated look, but does not want to use chlorine or other chemical additives. It combines the aesthetics of a classic pool with the benefits of natural bathing water.

What is a biopool?

A biopool is a swimming pool that is operated without chlorine or UV light. Instead, the water is purified by a biological filter system and natural processes. The result is 100% biological water that does not need to be renewed.

  1. Chlorine-free bathing: Enjoy pure water without irritation and side effects from chemicals.

  2. Ecological: A sustainable alternative to conventional swimming pools with no harmful impact on the environment.

  3. No water change: The biological balance maintains optimum water quality without having to drain the water.

  4. Optional equipment: add heating, cover, counter-floating system and more for optimum comfort.

How biological purification works

What is the difference?

The main difference between a biopool and a conventional pool lies in the way the water is purified. While conventional pools are disinfected with chlorine or UV light, the biopool relies on natural biological processes. This makes it not only more environmentally friendly, but also gentler on skin and hair. A biopool is a sustainable alternative for anyone looking for a natural, low-maintenance pool with the look of a conventional pool. It offers you a unique bathing experience and helps to protect the environment at the same time.
