Advanced Filtration Technology

The Nexus+ system uniquely combines a two-stage filtration process that enhances both mechanical and biological cleaning:

• Award-Winning Filter Media: Incorporates specialized media to deliver outstanding filtration performance.
• Dual Filtration Stages: A central chamber filled with K1 Micro Media mechanically traps small debris, while the outer chamber houses innovative K+Media for rapid biological maturation.
• Enhanced Flow and Solids Handling: The design of the K1 Micro beads promotes superior water flow with minimal backpressure, ensuring that your pump works efficiently.

EAZY Filter – Mechanical Filtration Redefined

At the heart of the Nexus+ filter is the stainless steel EAZY filter, engineered to provide robust mechanical filtration:

• Durable Construction: Crafted from high-quality stainless steel, it houses the K1 Micro Media in a central chamber.
• Clog-Free Design: Its unique pattern of slots optimizes water flow and prevents clogs, ensuring consistent performance.
• Clear Lid: Monitor the filtration process easily with a transparent lid that keeps debris out while showcasing the media at work.

Easy Installation & Automatic Upgrades

The Nexus+ filter is engineered with the homeowner in mind. It can be configured in either a pump-fed or gravity-fed setup depending on your pond’s design. Maintenance is simple – a quick backflush using an air pump (not included) clears debris, and internal components are easily removable for deeper cleaning. For those seeking convenience, an upgrade to an automatic cleaning system is available.

• Flexible Setup: Install the filter in a pump-fed or gravity-fed configuration with ease.
• Backflush Made Simple: Switch valves and insert a slide plate to agitate the media using an air pump.
• Optional Automation: Upgrade your system to fully automate the cleaning process for hassle-free maintenance.

Optional Filter Lid

Protect your investment with the tailored Nexus+ Filter Lid:

• Debris Protection: Prevents unwanted particles and weather-related issues from compromising the filter.
• Secure Fit: Designed to fit seamlessly over both the 220+ and 320+ models.
• Robust Materials: Made to endure even the harshest conditions, ensuring longevity and performance.

Technical Specifications

*Ensure your air pump is powerful enough to move the additional K+Media if you choose to increase biological filtration – refer to the product manual for further details.

How It Works

The Nexus+ filter operates as an integrated mechanical and biological system. Water enters through the inlet into an inner chamber where a vortex effect allows larger solids to settle. It then passes through the EAZY filter – a static bed of K1 Micro Media that traps finer particles. The pre-filtered water subsequently flows into the outer chamber where the dynamic K+Media moving bed fosters rapid bacterial growth. Here, beneficial bacteria break down ammonia and nitrites into less harmful nitrates before the water exits through the outlet back into your pond.

Installation Guide

Pump-Fed Setup

In a pump-fed configuration, a submerged pump directs water into the filter. Once processed, the water returns to the pond via a waterfall or a large-diameter pipe. It is recommended to install a UV unit downstream to match your pump’s flow rate and pond size.

Gravity-Fed Setup

For gravity-fed installations, ensure the water level in the filter is aligned with the pond's surface. Water flows from a 4" bottom drain upward through the filter. The pump, located after the filtration unit, then recirculates the cleaned water back to the pond. As with pump-fed systems, a properly sized UV unit is advised.
