What makes a natural swimming pool?
By nature, these are pools that are chlorine free. They feature two segments for vegetation and swimming with the former serving as the natural filtration system as against the chemical cleaning process featured by the conventional pools. Originated in Austria and Germany and popularized in the UK, this concept is picking up in the US.
How does cleaning happen without the use of chemicals?
The plant zone or regeneration zone does the filtering function. Plant life including flag irises and water lilies has the capacity to keep phosphate and nitrate levels under check thereby keeping the pond algae free. Gravel is also an important component in filtering the water.
How is the water moved in the pool?
It is necessary that the water is not stagnant and is always in motion. You can achieve this through a waterfall set up or a small pump. This will add more beauty to the pond at the same time helping in the filtration process. This set up can also help attract wild life like birds, dragon flies and tadpoles. They shall in turn help control the proliferation of insects.
How do we compare the costs of constructing a natural and a conventional swimming pool?
Since a natural swimming pool involves two zones, the initial cost of setting it up could be a bit more than the conventional kind of ponds. But, working out the cost per square meter, the cost might be more or less the same. The gain is on the long run without any need to invest on costly cleaning process.
