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.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"color: #000000\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"color: #000000\"\u003eThis 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.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"color: #000000\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"color: #000000\"\u003eAll Evo Nexus 320 Filtration Systems ship directly from the supplier, with delivery typically taking 3–5 working days.
