Why Evolution Aqua Is the Top Choice for Koi Pond Filtration
When it comes to ensuring the health and clarity of your Koi pond, the filtration system you choose plays a crucial role. Evolution Aqua Nexus EAZY 220+ and 320+ are top-of-the-line pond filtration systems designed to provide optimal water quality for your Koi, ensuring they thrive in a clean, healthy environment. In this guide, we will explore everything you need to know about these innovative filtration systems, from their features and installation to maintenance and cleaning.
Understanding the Evolution Aqua Nexus EAZY Series
What is the Nexus EAZY 220+ and 320+?
The Evolution Aqua Nexus range is designed specifically for Koi ponds, providing both mechanical and biological filtration in one compact unit. The Nexus EAZY 220+ and 320+ are two of the most popular models in this range, each catering to different pond sizes and requirements. These systems integrate advanced filtration technology to offer the best possible solution for clear, healthy pond water.
- Nexus 220+: Ideal for Koi ponds up to 18,000 litres.
- Nexus 320+: Suitable for Koi ponds up to 34,000 litres.
Both models feature Evolution Aqua’s signature filtration media, including K1 Micro and K1+ media, which deliver exceptional performance in keeping pond water clean and free from harmful waste.
Key Features of the Nexus EAZY 220+ and 320+
1. K1 Micro and K1+ Filtration Media
The Nexus EAZY systems are equipped with two types of media: K1 Micro and K1+. Both offer an incredible surface area for beneficial bacteria to thrive, aiding in both mechanical and biological filtration. The K1 Micro media is designed to trap fine particles and debris, while the larger K1+ media is optimized for biological filtration, converting toxic ammonia and nitrite into harmless nitrates.
2. Fluidized Bed Technology
The Nexus EAZY series uses fluidized bed technology to create a moving bed of media. This setup encourages optimal bacterial growth while ensuring efficient filtration without compromising water flow.
3. Self-Cleaning Mechanism
One of the standout features of the Nexus EAZY filters is the self-cleaning system. The media in the filter is aerated, allowing the system to agitate and clean itself with minimal effort. By turning a valve, you can clean the filter without removing the media or making a mess, which greatly simplifies maintenance.
4. Compact and Robust Design
Despite offering powerful filtration, the Nexus EAZY 220+ and 320+ are designed to be compact and easy to install. Constructed from high-quality, weather-resistant materials, these filters are built to last in any pond environment.
How the Nexus EAZY 220+ and 320+ Filters Work
Mechanical Filtration with Eazy Filter Technology
The Eazy filter is the heart of the mechanical filtration process in the Nexus systems. Water from the pond enters the filter and flows through the K1 Micro media. As the water moves through the media, larger particles such as fish waste and debris are trapped. The K1 Micro’s fine surface texture also captures smaller particles, improving water clarity and removing suspended solids from the pond water.
Biological Filtration and the Role of K1+ Media
After undergoing mechanical filtration, the water moves into the biological filtration chamber, which contains K1+ media. This media is designed to provide a habitat for beneficial bacteria that break down ammonia and nitrite, which are harmful to fish. As the bacteria consume these toxins, they convert them into nitrate, a much less harmful substance that can be absorbed by plants in the pond.
Fluidized Bed for Improved Performance
In the Nexus EAZY systems, the outer chamber uses fluidized bed technology to keep the K1+ media in constant motion. This movement encourages aeration, which is critical for the bacteria to thrive. The fluidized bed setup also prevents media clumping, ensuring efficient filtration even over time.
Nexus EAZY 220+ vs Nexus EAZY 320+: Which One Is Right for You?
Choosing the Right Nexus Model for Your Pond
The Nexus 220+ and Nexus 320+ are designed for different pond sizes and fish loads. Here’s a quick comparison to help you decide which system best fits your needs:
Nexus 220+
- Pond Size: Ideal for ponds up to 18,000 litres (approx. 4,000 gallons).
- Flow Rate: Capable of handling up to 10,000 litres per hour.
- Media Capacity: 150 litres.
- Dimensions: 1260mm (L) x 1110mm (W) x 850mm (H).
- Best For: Small to medium-sized Koi ponds with moderate fish loads.
Nexus 320+
- Pond Size: Suitable for ponds up to 34,000 litres (approx. 7,500 gallons).
- Flow Rate: Can handle up to 13,000 litres per hour.
- Media Capacity: 300 litres.

- Best For: Larger Koi ponds or ponds with a high fish stocking density.
If you have a smaller pond or are just starting out with Koi, the Nexus 220+ will suffice. However, for larger ponds or if you plan to increase your fish stock in the future, the Nexus 320+ provides more powerful filtration and greater capacity.
Installing Your Nexus EAZY Filter
Step-by-Step Installation Process
Installing your Nexus EAZY 220+ or 320+ filter is a straightforward process if you follow the proper guidelines.
1. Choose the Right Location
Select a flat, stable surface that is at least 1.2 meters by 1 meter in size. Ensure the area is easily accessible for cleaning and maintenance.
2. Set Up the Plumbing
Depending on your pond setup, you can choose between gravity-fed or pump-fed installation.
- Gravity-Fed: This system relies on gravity to pull water into the filter. Water flows directly from the pond into the Nexus filter chamber.
- Pump-Fed: A pump pushes water into the Nexus system. This setup requires additional piping but can be useful if the filter needs to be placed above the pond level.
3. Connect the Return Pipes
Ensure that the return pipes direct the filtered water back into the pond, either through a waterfall or a pond return pipe.
4. Prime the System
Once the plumbing is complete, you can fill the filter with water and prime the pump. Ensure that all valves are properly adjusted to facilitate water flow.
Fine-Tuning and Testing
Before running the system at full capacity, make sure to test the flow rates and check for leaks. Adjust the air valve and waste valve to optimize the self-cleaning process and ensure the filter is functioning at its best.
Cleaning and Maintaining Your Nexus EAZY Filter
Easy Maintenance with the Self-Cleaning System
The self-cleaning mechanism in the Nexus EAZY system makes maintenance incredibly simple. Here’s how to clean the filter:
- Turn Off the Pump: Switch off the pond pump to stop water flow.
- Close Valves: Isolate the filter by closing the necessary valves.
- Agitate the K1 Micro Media: Use the air valve to agitate the K1 Micro media, dislodging trapped waste.
- Release Waste: Open the waste valve to expel dirty water from the filter.
- Refill the System: After the waste has been removed, close the waste valve and allow clean water to enter the filter.
- Restart the System: Turn the pump back on and allow the filter to resume normal operation.
Regular Maintenance Schedule
- Daily: Check the water levels in the filter and ensure that the pump is running smoothly.
- Weekly: Perform a quick visual inspection and clean the filter media if necessary.
- Monthly: Complete a thorough cleaning of the filter and check all valves and connections for any wear or damage.
