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.

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

As with the natural pool, the biopool also has the Pool for Nature filter, in which microorganisms colonize and purify the water. In contrast to a swimming pond and a natural pool, the biopool does not contain any plants. The filter is usually installed under a wooden deck and no basement or garden shed is required for its installation.

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.

Biological water treatment

The filter area for the biological water treatment of your natural pool only takes up a small part of the entire surface of the natural pool. This ecological alternative to water treatment uses neither chlorine nor chemicals and can also do without plants. And for those of you who get cold easily, there is also the option of installing a heating system to achieve higher temperatures.

If you already have a pool...

it is possible to turn it into a natural pool! All the accessories of a classic swimming pool can also be integrated into our natural pool: Massage jets, counter-current system, heating, cleaning robot, overflow channel or lighting. As far as securing your natural pool is concerned, we can offer you an automatic cover. This allows you to enjoy your wellness area in the garden in absolute peace and quiet.
