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