What is the Evolution Aqua Nexus?
Overview of the Nexus Filtration System
The Evolution Aqua Nexus is a combined mechanical and biological filtration system designed specifically for koi ponds and large water gardens. It features an advanced moving bed filtration technology, which allows beneficial bacteria to thrive and break down harmful waste efficiently.
Key Features and Unique Benefits
- Mechanical filtration with K1 Micro Media – Traps solid waste and debris
- Biological filtration with K1 Moving Bed Media – Promotes beneficial bacteria growth
- Self-cleaning design – Reduces manual maintenance effort
- Energy-efficient operation – Saves power while maintaining superior filtration
- Suitable for medium to large ponds – Handles varying water volumes effectively
How the Evolution Aqua Nexus Works
Mechanical Filtration Process
When water enters the Nexus, it first passes through the Eazy Filter, where solid waste and debris are trapped. This stage ensures that only smaller particles proceed to the biological filtration chamber.
Biological Filtration with K1 Media
The second stage utilizes K1 Moving Bed Media, a specialized filtration medium that provides an ideal surface for beneficial bacteria to grow. These bacteria break down harmful ammonia and nitrites, converting them into less toxic nitrates.
Self-Cleaning Mechanism
The Nexus system includes a self-cleaning function, which makes maintenance incredibly simple. By activating the air pump and draining waste from the Eazy Filter, you can quickly clean the system without disrupting the biological filtration process.

How to Select the Right Size for Your Pond
The size of the Nexus system you need depends on:
- Pond volume – Larger ponds require more filtration capacity
