Myriophyllum spicatum -
An important aquatic plant that plays a key role in water filtration and maintaining biological balance in ponds and natural swimming pools (BIOpools). Thanks to its ability to oxygenate water efficiently and absorb large amounts of nutrients, it helps suppress the growth of filamentous algae. It is popular not only in BIOpools but also among aquarium enthusiasts. It is planted at depths ranging from 10 cm to 2 meters, where it creates a natural and healthy habitat for aquatic life.
Submerged plants play a crucial role in the natural filtration process in BIOpools. They are strong competitors to filamentous algae because they consume a large amount of nutrients directly from the water, limiting algae growth. As they grow upward from depths of approximately 60 cm to 2 meters, they also block light and warmth that algae need to thrive.
Well-known species include Canadian waterweed, which remains entirely submerged, and Crassula recurva, whose flowers can appear above the surface. In addition to cleaning the water, these plants are also excellent oxygenators. They produce oxygen and absorb phosphates, one of the main nutrients that feed algae. This greatly improves water quality and supports a healthy, balanced ecosystem in the BIOpool.
This group of plants is essential in any BIOpool. It is recommended to plant at least five to eight different species, as each submerged plant has a specific function. Together, they also contribute to the formation of biofilm, which plays a vital role in natural filtration.
The right combination of submerged plants is necessary to maintain a clean, balanced, and fully functional BIOpool without the need for chemical treatments.
