Evolution Aqua Nexus 220+ Complete Filter System Set
Complete Koi Pond Filtration System bundle with Pump, UV and Aeration
The Evolution Aqua Nexus 220+ Complete Filter Set provides a fully matched filtration solution for koi ponds up to 18,000 litres. Rather than selecting components individually, this system combines mechanical filtration, biological processing, UV clarification and aeration into a balanced package designed to operate efficiently together.
The set includes the Nexus 220+ filter supplied with a genuine Evolution Aqua lid as standard. In addition, it incorporates a correctly sized circulation pump, UV clarifier and air pump. As a result, the entire system operates within optimal flow and biological parameters from day one.
Because each component is carefully matched to the Nexus 220+ operating capacity, the system delivers stable water clarity and consistent long term biological performance.
Save Over £200 Compared to Buying Separately
When purchased as a complete system, this package represents a saving of over £200 compared to buying each component individually at standard retail pricing.
Instead of sourcing the filter, lid, pump, UV clarifier and air pump separately, this bundle ensures:
- All components are correctly matched
- Installation is simplified
- Compatibility is guaranteed
- Overall cost is reduced
Therefore, the Nexus 220+ Complete Filter Set provides both technical and financial advantages for serious koi keepers.
What Is Included in the Complete Set
- Evolution Aqua Nexus 220+– Advanced mechanical and biological filtration in a single compact unit
- Evolution Aqua Nexus 220+ Lid – Protects your filtration system while ensuring seamless integration into your pond setup
- Evolution Aqua Varipump 10,000 – Adjustable, energy-efficient pond pump for maintaining optimal water flow
- Evolution Aqua EvoUV 55w – High-performance UV clarifier to eliminate green water and harmful pathogens
- Evolution Aqua Airtech 75 Air Pump – Reliable aeration system to increase oxygen levels and support biological filtration
Each component has been selected to operate within the recommended 6,000 litres per hour flow range of the Nexus 220+.
Optional Automatic Cleaning Upgrade
This complete set includes the Nexus 220+ filter in its standard manual cleaning configuration.
For pond owners seeking fully automated Eazy chamber cleaning and reduced hands on maintenance, the Nexus Automatic Cleaning Kit can be added as a separate upgrade.
There are two versions available:
- Evolution Aqua Nexus Automatic Cleaning Kit – Gravity Fed
- Evolution Aqua Nexus Automatic Cleaning Kit – Pump Fed
It is important to select the correct version to match your installation type. The Nexus 220+ supplied in this bundle is auto ready, allowing straightforward installation of the appropriate automatic kit at any time without modifying the main filter body.
This provides flexibility for future upgrades while keeping initial setup straightforward.
Advanced Mechanical and Biological Filtration
The Nexus 220+ combines vortex settlement, fine particle capture and moving bed biological filtration within a single integrated unit.
Firstly, water enters the inner vortex chamber where heavier solids settle naturally. This reduces load on the mechanical stage.
Next, water passes through the Eazy section containing 18 litres of K1 Micro media. This stage captures fine suspended particles and improves clarity before biological treatment begins.
After mechanical separation, water moves into the outer chamber containing 50 litres of K+ media. Continuous aeration keeps this media in motion. Consequently, nitrifying bacteria receive high oxygen levels and efficiently convert ammonia and nitrite into nitrate.
This dual stage process maintains stable water parameters in medium sized koi systems.
Correctly Matched Circulation Pump
The Evolution Aqua Varipump 10,000 provides adjustable flow control, allowing precise matching to pipework configuration and head height.
Maintaining correct dwell time inside the filter is essential. Therefore, adjustable flow ensures mechanical capture and biological conversion operate efficiently.
Integrated UV Clarification
The Evolution Aqua EvoUV 55w supports effective green water control by neutralising single celled algae as water passes through the ultraviolet chamber.
When matched to correct flow rate, this UV output maintains clarity during warmer months when algae pressure increases.
Dedicated Moving Bed Aeration
The Evolution Aqua Airtech 75 Air Pump supplies consistent airflow to the biological chamber. Continuous aeration prevents media stagnation and supports efficient bacterial colonisation.
Because biological conversion depends heavily on oxygen availability, proper aeration directly influences ammonia stability.
Flexible Installation Options
This system can operate in either configuration:
- Pump Fed – Water is pumped from the pond into the Nexus before returning via gravity.
- Gravity Fed – Water flows naturally from bottom drains into the Nexus, and the pump returns filtered water to the pond.
Both configurations provide reliable high performance filtration when correctly installed.
Genuine Nexus Lid Included
This complete set includes a genuine Evolution Aqua Nexus lid as standard.
The lid improves insulation, protects internal components from debris and UV exposure, and provides a cleaner filter bay finish.
