Nexus220+
The Evolution Aqua Nexus220+ filter is a moving bed biological and mechanical filter suitable for koi ponds up to 18m³. The award winning Nexus Plus Filter design offers koi enthusiasts excellent value for money and is cost-effective to run.
Water enters the inner chamber of the Nexus220+ via an inlet. The inner chamber functions as a vortex causing larger solids to settle out. Water then passes through the stainless steel ‘Eazy’ which contains K1 Micro Media that harvests finer waste particles. The Eazy is cleaned by diverting the air from the outer chamber using the air valves, and waste discharged by opening the larger waste ball valve.
Water next flows into the outer chamber, where biological filtration takes place. The outer chamber contains hundreds of K1+ Media. These small plastic media have a high surface area to maximize the number of filter bacteria they can support. The bacteria perform an essential role in breaking down organic waste that is harmful to your fish. Aeration causes the K1+ Media to continually turn over, creating a ‘moving bed’. The aeration provides oxygen to the bacteria helping them thrive, and the action of the air bubbles agitates the media helping to ‘slough off ‘ dead colonies – ensuring optimal colonisation by living micro-organisms.
The Nexus220+ is simple and cost-effective to run, requiring just one filter pump to recirculate the water and one air pump for the moving bed. We would also recommend incorporating a UV Clarifier to sterilize your water and prevent green water.
- Recommended air pump: Evolution Aqua Air Pump (Air Pump 75 is suitable for the 50 litres of K1+ media supplied)
- Recommended filter pump: Evolution Aqua Varipump (Varipump 10000 is ideal for most installations)
- Recommended UV clarifier: Evolution Aqua evoUV or evoUV Titanium (model choice depends on your pond volume, sunlight exposure and fish stocks)
The Nexus 220+ is designed for both pump fed or gravity fed installations (see instruction manual below). It can also be upgraded with the Nexus Automatic Cleaning System (supplied separately) for automatic cleaning cycles (comes supplied with the factory fitted fixings already in place for easy installation).
