Bio swimming pool

Are you attracted to swimming in clean, chemical-free water in a beautiful natural environment with a view of the beauty of blooming water lilies? This can also be done in our newly built bio-swimming pool.
The pool itself, with an area of approximately 1400 m2, is divided by a wooden bridge into a children’s section and a section for adults. The water depth in the children’s section is from 0 to 60 cm, in the adult section from one to two meters. The gently sloping surface of the pool provides enough space for both swimmers and non-swimmers. The water temperature in July is around 22-26 degrees.
The enclosed area of the bio-swimming pool also includes an area intended for relaxation right next to the pool with the possibility of renting a wooden deckchair for the whole day.
Water quality is regularly monitored during the summer months based on laboratory analyzes of the samples taken. In addition to this page, we publish the results of individual water analyzes on our Facebook page Lake L.A.


Water treatment in our bioswimming pool is handled by high-quality biotechnology, in the form of external biofiltration and the technology itself. The initial treatment of water already takes place in the coastal biological zones of the pool. However, the main phase of water purification takes place in the filtration (regeneration) part – the external biofilter. Water from the bio-swimming pool flows into this external biofiltration using pumps.

The essence of the entire water purification process is the interplay of several factors. Its basis is aquatic plants. Without them, the self-cleaning function of the pool would not be possible. We used all types of aquatic plants for planting. Their species diversity will guarantee the proper functioning of the biological swimming pool and limit the occurrence of algae to a minimum. They are represented in our filter

The most effective filter system of a biopool is zooplankton. Thanks to these tiny animals, the water is constantly filtered without the use of any technology. Zooplankton includes a group of free-swimming aquatic species such as small crustaceans and protozoa. Above all, daphnia, gills, barnacles and cyclops play an important role in self-purification of water. For these small animals, algae are the basic food component. Zooplankon is able to filter out hygienically important bacteria in the entire volume of water from the lake in 3 to 7 days. Its reproduction works on the principle of self-regulation, and its number changes proportionally to the amount of algae.
Biofilm, also called organic turf, basically creates self-cleaning in the pool. It consists of bacteria, algae, fungi and unicellular organisms. they are most often found in vegetation in all areas of the lake or in filters that are supplied with sufficient oxygen. It is mainly in gravel, stones and all plants.

Over time, various sediments, mainly of organic origin, settle on the bottom of the pool and especially its regeneration part. This organic matter is the basic food for aquatic snails, worms, mussels, insect larvae and all other bottom-dwelling animals, generally referred to as the benthos. By this decomposition of organic matter into simple mineral components, the benthos is of great importance for the preservation of the natural ecological balance in the biobasin.

Of course, suitable technology also contributes to the cleanliness and overall functionality of the biopool. Here, however, it must be remembered that systems with the use of less technology are more stable. In our case, the basic elements of technology include pumps, surface dirt collectors – skimmers, and a fine mechanical filter. Our indispensable helper is an extra powerful pond vacuum cleaner.
