Plant filters for swimming ponds and fish ponds https://www.naturagart.de Plant filters for swimming ponds and fish ponds without filtration The video presents the filter trench technology that has been consistently developed at Naturagart since the 1980s. This method is based on the natural purification of water as it occurs in nature. Pollen, leaves and other dirt particles that get into the pond act like fertilizer for algae. Underwater plants play an important role because they absorb the nutrients dissolved in the water and thus deprive the algae of their livelihood. Since underwater plants in swimming ponds and fish ponds are often unwanted or eaten by fish, these plants must grow in a separate filter trench through which the water is channeled. ???????????????????????????????????????????????????????? ???????????? ????????????????????????????????????̈???????????? The underwater plants growing in the filter trench, such as hornwort, bind nutrients and thus prevent algae growth. The filter ditch is filled with sediment from the pond, which serves as a source of nutrients for the aquatic plants. The water flows slowly through the ditch, causing particles to settle on the bottom and clean water to reach the pump. This transports the purified water into a small stream, which returns it to the pond. The water is also filtered through a UV system to ensure optimal visibility. ???????????????????????????? ???????????? ???????????????????????????????????????????????? ???????????????????????????????? The filter ditch only needs to be cleaned every five to ten years, while the technical filter needs to be cleaned every three to four weeks. Thanks to this efficient technology, maintenance is kept to a minimum and the water stays clear all year round. Filter trenches are therefore a central element in the NaturaGart pond construction system, as they mimic the natural processes of water purification and ensure permanently clear water in swimming and fish ponds. ▶️ https://www.naturagart.de/Teiche/Rich... ????̈???????????? ????????????????????????????????????????
