Biological pond is a landscape type that has become common in the recent years. Natural plants and beneficial bacteria grow in the ecosystem of the pond. The self-cleaning biological pond is a part of new generation landscape projects. Biological pond construction begins with the exploration of an expert team. Many factors are considered, from soil structure to geographical characteristics of the area, from climate conditions to other environmental factors. Living ecosystem of the biological pond is evaluated at the planning stage. Materials such as pier, deck, natural stone, gravel and rock are also used in the biological ponds. Different visual elements such as plants, reeds, fountains, sculptures and flowers are also included in the project. The biological pond, which gives the region a natural ambiance arising its living ecosystem, does not require water cleaning costs as it is self-cleaning.
