System Living Pool

How does a Living Pool „work“?

Having two separate water cycles allows an economically-efficient and energy-saving use of the pumps. During the first cycle, the surface of the water is skimmed and floating particles are removed from the water. The pump is only in operation during the day. During the second cycle, organic impurities are degraded and phosphorous is eliminated from the water. This pump runs continuously during the bathing season. Water features such as a mill stone or waterfall can be integrated in both water cycles. Biotop has always attached a great deal of importance to designing technical components that are simple and easy for the user to understand.

The Living Pool looks like a conventional pool but is in fact a fully functional biological pool. The Biotop Living Pool requires absolutely no chlorine or any other chemicals and offers the ultimate swimming enjoyment in crystal clear water.


Many homeowners dream of being able to swim in their own backyard, but hesitate to use chemicals in their pool – especially when children will be enjoying the pool as well. Chlorine can not only be damaging for the natural environment, but also unhealthy for people. The Living Pool turns swimming into an uplifting experience for the senses.


This uncomplicated system has many advantages. For example, the pool does not have to be emptied for the winter; there is no need to remove the water in the pipes, and the pumps remain in place. Only the filter material of the "PhosTec-Upstream" has to be replaced every few years. This is a major convenience that all swimming pool owners will no doubt appreciate.

Technical components

1 Submersible pump chamber

Biotop has developed a special water circulation concept for its Living Pools. The pump is completely submersed in water in a chamber, allowing water to flow to it simply by the force of gravity instead of being “sucked in” by the pump. Mounted at the bottom of the chamber, the pump conveys the water back into the pool through pressure pipes.


  • Submersed pumps are very quiet, making almost no noise
  • Due to the low noise level, the chamber can be installed underneath the wooden deck
  • The pump does not need to be uninstalled for winter
  • The pipes do not need to be emptied for winter
  • Incoming and outgoing pipes can be regulated individually
  • The submersed pump is optimally cooled by the water

2 Curved Screen Skimmer

The purpose of the curved screen skimmer is to remove floating particles from the Living-Pool. The water flows over a curved screen with a mesh width of only 0.3 millimetres that removes even the smallest contaminants. A sophisticated mechanism controls the water flow via a flexible flap so that the correct amount of water always flows over the screen. Biotop was granted a European patent for this development.


  • Even the finest floating particles are eliminated from the system
  • Nutrients are removed from the water
  • The screen is self-cleaning and therefore cannot become clogged

3 Pool robot

The pool robot cleans the walls and bottom of the pool basin automatically.


4 Bio-Compact Filter

Water flows through the filter vertically from top to bottom and is biologically cleaned along the way, i.e. impurities causing turbidity and organic compounds are broken down by bacteria. The result is crystal-clear water. To optimize the cleaning performance of the bacteria, water flows through the biofilter permanently. The biologically cleaned water then continues into the PhosTec Upstream filter.


  • Biological cleaning without the need for chemicals
  • Requires no electrical power
  • The bio compact filter is comparatively small in size and installed under the deck, invisible to the user

5 Phosphatfilter „PhosTec Ultra“


The PhosTec Upstream phosphate filter is installed in every Living Pool by default. It binds the phosphorus dissolved in water, thus preventing the growth of algae efficiently and without the use of chemicals. In this way, the algae are effectively “starved”. The water flows through the filter from bottom to top to minimize the risk of clogging the filter, and the nutrient-poor water is then pumped back into the pool by a small pump. Biotop was granted a European patent for the combination of the biofilter and PhosTec Upstream filter.


  • Phosphorus is removed from the water efficiently and reliably
  • Small size saves space
  • Easy handling
  • Simple replacement of the filter material
  • Long life span
