Evolution Aqua Nexus 220

The Nexus 220 and 320 filtration systems deliver dramatically improved levels of water clarity for Koi ponds. Building on the success of the award winning Nexus range this new generation of filters cleverly combine mechanical and biological filtration into one advanced filter system whilst being incredibly easy to clean and simple to install. The Nexus 220 is suitable for ponds up to 18000 litres while for larger ponds the Nexus 320 can be installed on ponds up to 34000 litres.

Features:

• The Nexus 220 and 320 feature a re-designed ‘Eazy’ filter which now utilises the all new K1 Micro Filter Media in a static bed to deliver improved levels of mechanical filtration.
• The Nexus filter systems also use the acclaimed K1 Media in the moving bed to deliver outstanding levels of biological filtration.
• Together this combination of filter media work to deliver crystal clear and healthy water.
• All Nexus filtration systems can be installed on pump fed or gravity fed setups depending on your pond configuration.
• Manufactured ready for easy upgrade to Automatic System.
• Nexus lids are available to cover the Nexus filter and also accommodate the Nexus Automatic System.

For best results, it is recommended that you use an Evolution Aqua Evo UV professional ultra-violet clarifier with these filters.

You can also increase the filters performance by adding an air pump and extra K1 media to the bio chamber. See the filters specifications for further details.
