We care about the environment!
In addition to its aesthetic qualities, the fountain is an excellent aerator, supplying the water reservoir with large amounts of oxygen, which is caused by the falling of previously lifted water. In the case of the basic version of the fountain, this is 21m3/h. As a result, the infiltration process in a polluted water reservoir is faster, which can be noticed in the first weeks of the fountain’s operation by the disappearance of the unpleasant smell from the reservoir.
Silting of the biologically active surface of the bottom worsens the living conditions of the organisms living there and reduces the food base for fish, limiting the number and diversity of invertebrates living at the bottom. The decomposition of sediments increases oxygen consumption, causes the formation of nitrogen, sulfur, and phosphorus compounds, and leads to the accumulation of hydrogen sulfide-saturated water in depressions in the bottom, as well as its turbidity and contamination as a result of bottom sediment movements.
In addition, the increased inflow of water-fertilizing compounds causes intensified photosynthesis and an increase in the amount of phyto- and zooplankton. Lushly developed algae produce excessive amounts of oxygen during the day, but at night they consume it, causing an oxygen deficit. This situation is a threat to the life of fish. Water blooms caused by the excessive growth of cyanobacteria, whose death is associated with the release of toxins, are dangerous to humans and animals.
Excellent oxygenation of the water in winter will prevent fish from dying when the reservoir is covered with ice. A floating fountain can also operate during the winter, but only if the water reservoir is deep enough.
