EAZY Filter for Mechanical Filtration
The stainless steel EAZY filter targets large and fine particles before they reach the main filter chambers. It improves water flow, reduces clogging, and keeps maintenance simple. A clear viewing lid lets you see the filtration in action and makes removal fast when needed.
Simple to Install, Maintain, and Customize
Nexus+ can be installed pump-fed or gravity-fed, giving you flexibility for different pond setups. Cleaning is done by turning valves to agitate the media with an air pump, sending debris out through a waste outlet without messy filter pads. Models produced after 2006 can be upgraded to an automatic system for hands-off cleaning.
Optional Tailored Nexus+ Filter Lid
A tailored Nexus+ lid protects your filter from falling leaves, dirt, and harsh weather. It fits securely over Nexus 220+ and 320+ units and helps keep your filtration system running efficiently. The lightweight design installs quickly and offers added peace of mind outdoors.
Advanced Filtration Technology
The Nexus+ uses two types of award-winning media to keep pond water exceptionally clear. Small debris is captured mechanically with K1 Micro Media before water moves to a separate chamber with K+ Media for biological filtration. High surface area media supports beneficial bacteria so the system matures quickly and maintains healthy water conditions.
