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.
