Why Evolution Aqua Is Trusted by Professionals
There are many reasons why pond keepers and aquarists globally trust Evolution Aqua:
Proven Filtration Technology
The brand is behind some of the most reliable mechanical and biological filtration systems on the market, including the Nexus 220+ and 320+, which are widely used in koi pond setups. These systems offer advanced mechanical filtration followed by powerful biological treatment, ensuring clear, healthy water.
Award-Winning Innovation
Evolution Aqua has received multiple awards for design and innovation. Their PURE Pond bacteria balls have revolutionized the way beneficial bacteria are introduced and maintained in pond systems, boosting biological filtration naturally and efficiently.
Comprehensive Product Range
They offer not just filters, but also air pumps, UV clarifiers, pond treatments, test kits, pipework fittings, and aquarium-specific equipment. This allows pond keepers to source complete systems from a single, trusted brand.
Sustainable Design
The company also focuses on eco-conscious design, with energy-efficient pumps and filters that help reduce running costs while delivering superior performance.
How Evolution Aqua Systems Work
Let’s break down how Evolution Aqua products contribute to clean, biologically balanced water:
Mechanical Filtration
The first stage is mechanical, where solid debris is physically removed from the water. In systems like the EazyPod, water enters and passes through a vortex chamber, where larger solids are settled and captured.
Biological Filtration
Once solids are removed, water flows through a media bed—typically K1 or K+ media. This is where biological filtration occurs: beneficial bacteria living on the media break down ammonia and nitrites, detoxifying the water and maintaining a stable ecosystem.
UV Clarification
In many setups, UV clarifiers such as the EVO UV series are added to eliminate green water caused by free-floating algae. UV light neutralizes algae cells, which are then filtered out mechanically.
Air and Water Pumps
Efficient water flow is ensured with Varipump or AquaAir systems. Oxygenation is essential for biological filtration to thrive, and these pumps maintain optimal flow rates and oxygen levels.
Which Evolution Aqua Product Is Right for You?
1. Nexus 320+
Ideal for large koi ponds (up to 34,000 liters), the Nexus 320+ offers high-capacity, low-maintenance filtration. Its innovative central Eazy filter and outer bio-media chamber ensure a two-stage process that’s easy to clean.
2. EazyPod Automatic
For smaller ponds or users seeking automation, the EazyPod Automatic self-cleans at scheduled intervals. It’s compact but powerful enough for koi ponds up to 10,000 liters.
3. EVO UV Clarifiers
These are available in various wattages (15W to 110W), suitable for ponds of all sizes. They eliminate green water effectively and are easy to install inline with your filtration system.
4. PURE Pond and PURE Aquarium
These are bacterial treatments in gel or ball form that introduce billions of beneficial bacteria into your system, perfect for spring startups or after water changes.
5. Varipump and Airtech
Varipump offers variable flow for high flexibility, and Airtech air pumps deliver reliable aeration for both ponds and filters, especially during hot seasons or high biomass loads.

Clearing Up Confusion
What size Evolution Aqua filter do I need for my pond?
Filter size depends on pond volume and fish load. For ponds under 10,000 liters, the EazyPod is sufficient. For larger koi ponds, opt for the Nexus 220+ or 320+.
Is Evolution Aqua only for koi ponds?
No, while koi pond products are popular, the brand also caters to garden ponds, natural swimming ponds, and aquariums.
How often should I clean my EazyPod or Nexus filter?
Manual versions require weekly checks and cleaning depending on fish load. Automatic models perform scheduled self-cleaning cycles.
Are Evolution Aqua filters energy efficient?
Yes. Paired with their Varipump or Airtech systems, the filters run efficiently with minimal electricity use, helping reduce ongoing costs.
Can I install an Evolution Aqua system myself?
Yes. Most of their products come with user manuals, setup videos, and community support, making DIY installation manageable. However, professional help is always recommended for large setups.
