Evolution Aqua Nexus 220+

Evolution Aqua Nexus 220+ Pond Filter - Advanced Filtration for Clearer, Healthier Ponds

The Nexus 220+ from Evolution Aqua is the next generation in pond filtration, combining mechanical and biological processes in one powerful and easy-to-maintain system. Building on years of proven Nexus technology, the 220+ model is enhanced with K+Media, an advanced filtration media that ensures faster bacterial colonisation, improved water quality, and long-term performance.

K+Media, now included as standard in the moving bed chamber, offers a class-leading total surface area of 1,350m² per m³ and 1,025m² per m³ of protected surface area, giving beneficial bacteria the optimal environment to thrive. Infused with minerals, calcium, magnesium, salt, and enzymes, this media accelerates bio-film development and shortens filter maturation times.

Designed for ponds up to 18,000 litres (4,000 gallons), the Nexus 220+ is Auto-Ready, with pre-installed fixings allowing for quick integration with the Nexus Automatic Cleaning System, making maintenance even more effortless.
