Evolution Aqua Nexus 220 Titanium
Advanced Koi Pond Filtration with Integrated Titanium UV Clarification
Includes FREE Genuine Evolution Aqua Nexus Lid. Supplied at no extra cost when purchased with this filter.
The Evolution Aqua Nexus 220 Titanium is a high performance koi pond filtration system designed for koi keepers who want excellent water clarity and long term water stability. It combines proven Nexus mechanical and biological filtration with Titanium enhanced 72w UV clarification. As a result, it delivers a complete all in one solution for koi ponds up to 18,000 litres.
Because everything sits within a single unit, installation stays straightforward and ongoing maintenance remains manageable. In addition, the integrated design helps maintain strong flow rates without unnecessary restrictions. Therefore, the Nexus 220 Titanium suits serious koi ponds where reliability matters.
Filtration Performance and Water Quality
The system uses the established Nexus two stage filtration process. First, pond water enters the central Eazy filter chamber, where a static bed of K1 Micro media captures solid waste and fine suspended particles. Consequently, debris does not break down in the pond, which improves clarity and reduces maintenance.
After this stage, water flows into the outer biological chamber. Here, a moving bed of K plus media creates an oxygen rich environment for beneficial bacteria. As a result, ammonia and nitrite convert efficiently into safer compounds. With capacity for up to 150 litres of K plus media, the Nexus 220 Titanium comfortably supports heavily stocked koi ponds.
What sets this model apart is its integrated Titanium enhanced UV system. Two UV lamps sit within a dedicated internal chamber, which ensures consistent contact time between water and UV light. Therefore, the system clears green water and suspended algae up to one and a half times faster than standard UV units.
Because the UV system sits inside the filter body, pipework stays minimal and flow efficiency improves. At the same time, pressure loss reduces, allowing the system to run smoothly and efficiently.
Maintenance remains simple and user friendly. All UV components stay easy to access, so bulb and quartz sleeve replacement takes little time. Furthermore, the Nexus 220 Titanium arrives factory prepared for the Nexus Automatic Cleaning System, making future upgrades straightforward.
Built from a durable, UV resistant and weather resistant body, the Nexus 220 Titanium delivers reliable performance year after year. Overall, it provides an excellent balance of mechanical filtration, biological processing and advanced UV clarification for koi ponds up to 18,000 litres.

Practical setup advice
Before ordering, think about how this product fits into the full pond setup. Compatibility, maintenance access, pipe or hose size and future servicing are often just as important as the headline specification. A product that is technically suitable can still disappoint if it is installed with restricted flow, poor access or the wrong supporting equipment.
Where possible, plan the main product and the accessories together. This makes installation neater, maintenance easier and the final system more reliable over time.
- Match the pump flow to the filter and pond volume, allowing for head height and pipework losses.
- Keep unions, valves and waste outlets accessible for cleaning and maintenance.
- Use suitable hose, pressure pipe or DN discharge pipework where specified by the manufacturer.
- Check compatible UV bulbs, quartz sleeves, media and spare parts before the pond season starts.
Plan this product as part of the complete filtration layout, rather than as an isolated item. Check the recommended flow rate, inlet and outlet sizes, waste connection, access for cleaning and the space needed for routine servicing before installation. A well matched filter system is easier to maintain and gives more reliable water clarity over the long term.
