Aquatic plants in the swimming pond

Plants in a swimming pond are only secondary to ornamentation: in the complex, aquatic ecosystem of the pond they serve as functionaries of pond ecology. We show you which plants contribute to a healthy pond and bring you pure bath water.

Plant the treatment area

In our case, we opted for a pervasive two-chamber system, which for most swimming pond owners was the best compromise between land use and the necessary treatment area.

The treatment area should be specifically equipped with cleansing aquatic plants. Some of them are presented here in selection.


Thousand leaves (Myriophyllum spicatum)

The "Eärige Tausendblatt" is a classical pond plant and particularly suitable for use in swimming ponds, as it is relatively sensitive to water changes and has a good filtering effect. The individual stems are 40 to 200 cm long. If this plant thrives well, your pond is healthy.



Kalmus is one of the most common pond plants, native to Asia and has spread to the northern hemisphere since the 15th century. Healing powers are attributed to a tincture from the roots of the shallow-water plant, and Kalmustinktur has been and still is used in Asian and Native American medicine. Also in Coca-Cola a little Kalmustinktur is included.

Kalmus reaches a height of 60 to 100 cm and should, like all aquatic plants, not be planted too densely - two plants per square meter suffice, otherwise the pond grows too rich. Ideal for the calamus is the shallow water zone at the edge of the pond to a depth of 20 cm.

Water Crowfoot

Water crowfoot

Water crowfoot is also a sophisticated aquatic plant, which is also visible on the surface and produces beautiful flowers. The nutrient consumption of this plant is comparatively high, this algae deprives the food base and the water remains clear. From time to time, however, the lush underwater web of the water crowfoot should be lightened; This also removes important nutrients from algae.

Canadian Waterweed

Canadian Waterweed

The Canadian Waterweed also removes algae vital raw materials and ensures a more ecologically balanced climate in the pond. Originally not present in our environment, the water plague was introduced in the 19th century by North American continent and spread rapidly throughout Europe and parts of Asia.

The water plague must be regularly cleared, as it has a strong, herbaceous growth and in a short time generates much biomass. However, it also has a good filter function.
