The Evo Nexus 320 Filtration System is a high-capacity, professional-grade pond filter designed for ponds up to 34,000 litres (7,500 gallons). This advanced system combines both mechanical and biological filtration in one compact and easy-to-install unit. The Nexus 320 features a redesigned Eazy Filter with K1 Micro filter media in a static bed, improving mechanical filtration and removing fine particles from pond water.
The outer chamber of the Evo Nexus 320 Filtration System contains a moving bed of K1 Media, which supports beneficial bacteria and filter feeders that convert harmful Ammonia and Nitrite into harmless Nitrate. The combination of the Eazy Filter, K1 Micro media, and K1 Media moving bed ensures crystal-clear water while maintaining a healthy environment for koi, goldfish, and other ornamental pond fish.
This Evo Nexus 320 Filtration System can be installed on both pump-fed and gravity-fed setups depending on your pond configuration. The recommended air pump size is 95 to ensure optimal movement of the K1 Media for biological filtration. Additional K1 Media can be added to increase biological capacity based on pond size and feed rates. The system is easy to clean, with the inner chamber acting as a vortex to settle larger solids before water passes through the Eazy Filter and K1 Micro media.
All Evo Nexus 320 Filtration Systems ship directly from the supplier, with delivery typically taking 3–5 working days. This makes it an excellent choice for pond owners looking for reliable, scalable, and high-performance filtration.
