Evolution Aqua Nexus 220+

Evolution Aqua introduces the Nexus320+ and Nexus220+, the latest advancements in their renowned Nexus filtration systems, offering unparalleled efficiency for Koi pond filtration. These filters feature the innovative K+ Media in the outer moving bed chamber, ensuring superior biological filtration and accelerated filter maturation. Additionally, the Nexus+ filters come “auto ready,” with pre-installed fixings for easy integration with the Nexus Automatic Cleaning System, simplifying maintenance and upgrades.

The Nexus+ operates as a comprehensive biological and mechanical filter system, starting with water entering the inner chamber, where a vortex action facilitates the settlement of larger solids. Subsequently, the water flows through the Eazy filter, effectively removing finer particles with the assistance of the static bed of K1 Micro filter media. The mechanically cleansed water then proceeds to the outer chamber, housing the new K+ Media Moving Bed, where biological treatment occurs before returning to the pond. Here, diverse strains of bacteria and filter feeders thrive on the extensive surface area of the K+ Media, converting harmful substances like Ammonia and Nitrite into less harmful Nitrate.

The Nexus+ filtration system ensures optimal water quality and the well-being of pond inhabitants through its efficient biological breakdown process. With its advanced design and integrated features, including factory-fitted fixings for seamless upgrades, the Nexus320+ and Nexus220+ redefine pond filtration, providing Koi enthusiasts with a reliable and effective solution for maintaining a healthy pond ecosystem.
