Experience industry-leading biological capacity and effortless maintenance with our range of Evolution Aqua Nexus filters and complete filtration systems. Trusted worldwide by dedicated koi keepers and pond professionals, the Nexus series combines mechanical solids separation and high-output moving-bed biological filtration within an integrated, circular footprint.
Our collection includes the popular Nexus 220 and larger Nexus 320 systems, alongside the latest Nexus+ models and automated cleaning upgrade kits designed for both gravity-fed and pump-fed installations. Each unit utilises an internal Eazy mechanical chamber packed with static media to capture fine physical debris, directing pre-filtered water outward into an aerated biological chamber filled with constantly tumbling K1 media. Cleaning requires no wet hands, simply turn the integrated air valve to agitate the mechanical core and dump the dislodged waste directly to the drain line in minutes. Explore our full Nexus filters collection to equip your pond with proven, British-engineered filtration built for exceptional clarity and long-term water quality.
