The Nexus 320 filtration systems deliver dramatically improved levels of clarity for 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 320 features 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.

For Nexus filters as shown in the images above, you can use the Type 3 upgrade kit. This kit upgrades the mechanical filter from an EAZY with K1 Media to an EAZY with K1 Micro
If you have a Nexus 200 / 210 or 300 / 310 filter manufactured between 2006 and 2014 you are able to upgrade the inner chamber to allow you to install the EAZY Type 3 filter, (as used in the Nexus 220 and Nexus 320).
To further identify your Nexus, it will not have a stepped section moulded into the outlet or either the Answer or sponges as the primary mechanical filter. Instead, the body of the Nexus will feature the wider outlet and it will be fitted with an EAZY filter.
When ordering your upgrade kit please ensure you order one for a Nexus 200 / 210 or Nexus 300 / 310 version.
The Type 3 Upgrade Kit comes with:
- New EAZY mechanical filter
- Supplied with K1 Micro in place in the centre of the Eazy.
- 18 Litres K1 Micro are supplied in a 220 EAZY

The Cetus Seive
K1 Media , K1 Micro
Maturing the K1 Media bio-media is important because a delicate eco-system is naturally developing for the bacteria involved in the nitrification process. K1 Media provides the maximum active surface area for the bacteria to colonise, more than other types of static media. It is this process which removes harmful ammonia and nitrite from the water.
As the K1 Media moves within the filter, it causes the old dead bacteria on the outside to be displaced. This makes space for new younger heavier feeding bacteria to rapidly colonise. Within the wheel is a protected surface which enables colonies of bacteria to naturally follow their lifecycle, of maturing, dying and then fueling the latter stages of the nitrification cycle. K1 Media has been designed to provide the best possible habitat for both young and mature beneficial bacterial colonies.
Unlike foam, matting, or other forms of static filtration media, the K1 Media is designed to move freely within your filter. The constant chaotic movement of the air from your pump, causes the media to self clean and thus requires no maintenance. This allows the filter to reach optimum effectiveness without the disturbance of periodic cleaning, avoiding unnecessary loss of bacteria within the filter. 50 Litres of K1 media will handle up to 250 grammes of food per day and for K3, 225 grammes of food per day. For retrofit of existing filters, K3 media is the most suitable due to its larger size and ease of control.
K1 media has been used by Evolution Aqua in Koi filtration systems for a number of years. This new type of filter media, K1 Micro, contains all of the benefits of traditional K1 media but is extruded in a much smaller form. The small wheel shaped filter media pieces provide a significantly increased protected surface area per cubic metre when compared to standard K1 for bacteria to colonise. This makes K1 Micro an ideal filter media for aquariums of all types where high level biological filtration is needed. K1 Micro can also be used to replace existing filter media
