Description
The Evolution Aqua Surge UV Clarifier is designed to deliver powerful UV sterilisation for koi ponds and ornamental pond systems.
Using high-output UV-C technology, the Surge UV effectively targets free-floating algae responsible for green water, helping restore clear and healthy pond conditions.
It also reduces harmful bacteria and pathogens, improving overall water quality and supporting fish health.
This makes it an essential addition to any koi pond filtration system where water clarity and biological control are a priority.
Key Features
✔ High output UV-C sterilisation
✔ Controls green water algae
✔ Improves pond water clarity
✔ Reduces harmful bacteria and pathogens

How the Surge UV Works
Water is passed through a sealed chamber where it is exposed to UV-C light.
This radiation disrupts the DNA of algae and microorganisms, preventing them from reproducing and clearing green water conditions over time.
The result is visibly clearer pond water and improved system hygiene.
Recommended Applications
- Koi ponds
- Ornamental ponds
- Filtration systems (Nexus, drum, bead filters)
- Green water control
- Algae prevention systems
- Quarantine systems
Installation Position
The Surge UV is installed inline within the return pipework after mechanical and biological filtration.
Typical setup:
Bottom drain → Primary filter (Nexus/Drum) → Biological filter → Surge UV → Pond return
Maintenance
- UV lamp replacement (typically annually)
- Quartz sleeve cleaning
- Regular inspection for performance
- Simple access housing design
Benefits
The Surge UV provides:
- Clearer pond water
- Reduced algae blooms
- Healthier fish environment
- Improved filtration efficiency
- More stable pond ecosystem
