Cascades

From the perspective of the user of a biological pool, waterfalls are a visual attraction due to their diversity in shapes and colors and especially due to the sound effect of dripping water. In summer, rain at home, without getting wet, brings a very pleasant feeling of freshness.

Waterfalls in biological pools are always poor in quantity of water that runs over the rocks, but rich in biodiversity. They are damp walls where water passes tirelessly through perforated stones. Thus, many streams of water travel a long way to precipitate the organic load that the water eventually brings. These waterfalls are true vertical filters.

Due to the verticality, the ever-present water and the rocky surface with a scarcity of substrates, waterfalls are a niche environment, where only specialists among plants, such as mosses and ferns, can survive. There are also a few vascular plants, such as water lettuce, which have the ability to settle in this special humid environment, to develop carpets of a lively green.

Water cascades are elements used in the water circulation system, where water returns from a biological filter to the biopool, or downstream of infinity edges, or in tight places where is little space available to implement other biological pool treatment systems.
