Enhancing Your Koi Pond Filtration with Evolution Aqua Nexus 220+

The Evolution Aqua Nexus 220+ presents an advanced filtration solution tailored for koi ponds, building upon the established technology of the globally recognized Nexus filters. The Evolution Aqua team has pushed boundaries further to elevate their flagship koi pond filter.

Key Features of Nexus 220+

Enhanced Filtration: Supplied with the new K+ Advanced Floating Filter Media in the moving bed outer chamber, this filter delivers significantly improved biological filtration and rapid filter maturation.

Auto-Ready Design: Nexus 220+ filters come “auto-ready” with pre-installed fixings, streamlining the process of upgrading to the Nexus Automatic Cleaning System.

How the Nexus+ Filter Works

The Nexus+ filter integrates innovative biological and mechanical filtration functionalities. Pond water enters via the inlet into the inner chamber, creating a vortex effect that allows larger solids to settle out. The water then traverses the Eazy filter, where the static bed of K1 Micro filter media efficiently removes finer particles in the mechanical filtration stage.

Clean water from the mechanical stage proceeds to the outer chamber, housing the new K+ Advanced Filter Media moving bed for biological treatment. Beneficial bacteria on the vast surface area of each K+ media piece break down harmful substances like Ammonia and Nitrite into less harmful Nitrate, ensuring a healthier pond environment.

New K+ Advanced Floating Filter Media

Evolution Aqua’s K+ Media, designed and manufactured in the UK, revolutionizes biological and mechanical filtration with its innovative design and class-leading surface area. Minerals and Enzymes added during production enhance its filtration efficiency and biofilm maturation speed.
