This is a perennial aquatic plant with excellent filtration capabilities.
Commonly used in natural swimming pools as well as in aquariums.
It's an effective oxygenator and, due to its high nutrient uptake, it helps suppress the growth of filamentous algae.
It is planted in gravel at depths ranging from 50 to 80 cm.
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.
