Easy to clean and built for consistent flow, the 320+ delivers exceptional water clarity with minimal maintenance.
Product Description
The Evolution Aqua 320+ is a high-capacity, all-in-one pond filtration system designed to deliver outstanding water clarity and biological performance for large koi and heavily stocked ponds. Manufactured by Evolution Aqua, the 320+ builds on the proven Nexus design, combining advanced mechanical filtration with powerful moving-bed biological filtration in a single, easy-to-maintain unit.
With upgraded internal design and modern filter media, the Evolution Aqua 320+ allows ponds to mature faster while maintaining consistently clean and healthy water conditions.
Advanced Mechanical & Biological Filtration in One System
Water enters the Evolution Aqua 320+ through the inlet and flows into the central inner chamber. This chamber creates a gentle vortex effect, slowing the water and allowing heavier solid waste to settle naturally before filtration begins.
The water then passes into the redesigned Eazy filter, which contains a static bed of K1 Micro filter media. This stage captures fine particles extremely efficiently, providing exceptional mechanical filtration and significantly improving water clarity.
Once mechanically filtered, water flows into the outer chamber where the biological stage of filtration takes place. Here, a moving bed of K1 Media provides a vast protected surface area for beneficial bacteria to thrive. These bacteria convert harmful ammonia and nitrite into less harmful nitrate before the clean water exits the filter and returns to the pond.
Key Features & Benefits:
Superior Mechanical Filtration: The upgraded Eazy filter uses K1 Micro media to trap fine waste particles more effectively than traditional media, delivering noticeably clearer pond water.
High-Capacity Biological Performance: The moving bed of K1 Media in the outer chamber supports large bacterial colonies, making the 320+ ideal for koi ponds with higher stocking and feeding levels.
Improved Flow Efficiency: The redesigned stainless-steel Eazy filter features optimised slot patterns, allowing water to flow evenly through the media for improved efficiency and consistent performance.
Easy Cleaning & Low Maintenance: Cleaning the Evolution Aqua 320+ is quick and simple. By operating the air and waste valves, trapped debris is agitated and flushed away without the need to dismantle the unit.
Excellent Solids Handling: The large central settlement area allows solid waste to collect effectively, reducing clogging and maintaining reliable flow rates.
Removable Eazy Filter: The Eazy filter can be easily lifted out if required, making deeper maintenance or inspection straightforward.
Auto-Ready Design: The 320+ is supplied “auto ready,” with factory-fitted fixings in place, allowing easy future upgrade to an automatic cleaning system.
How the Evolution Aqua 320+ Works
- Pond water enters the inner chamber and slows, allowing heavy solids to settle
- Fine particles are captured in the Eazy filter using static K1 Micro media
- Water flows into the outer chamber for biological treatment via moving K1 Media
- Clean, filtered water exits the system and returns to the pond
During cleaning, air is diverted into the Eazy filter to agitate the K1 Micro media, releasing trapped waste which is discharged through the waste outlet.
Reliable Biological Filtration
The moving bed chamber is where biological filtration takes place. Beneficial bacteria living on the K1 Media convert ammonia and nitrite produced by fish waste and uneaten food into nitrate. For ponds with higher feed rates, additional K1 Media can be added to increase biological capacity.
For optimal performance, maintain a pond pH of 7.0 or above. As with all biological filtration systems, efficiency may reduce in colder water temperatures.
Ideal For
- Large koi ponds
- Heavily stocked ornamental ponds
- Pond keepers seeking excellent clarity with minimal maintenance
- Installations requiring high biological capacity and reliable performance
