Professional modular filter system for large natural and swimming ponds up to 530 m³ and koi ponds up to 100 m³ for outstanding water quality in the smallest of spaces – thanks to particularly high filter performance with intelligent control functions and intelligent self-cleaning function for unique freedom from maintenance (drum filter module). All settings can be conveniently controlled via APP by connecting the system to the OASE Control System. The removal of pollutants is even more effective thanks to the high-performance OASE PondPads filter media and develops its optimum performance in the new fluidised bed process (moving bed). For large pond owners who want more, high degradation rates of ammonium, ammonia, nitrite and nitrate through larger Moving Bed modules for up to 150 litres of Hel-X, especially in combination with the new OASE PondPads biofilter media, ensure even greater performance.
