How UV Sterilisation Works
Water passes through a sealed chamber where it is exposed to UV-C light.
This disrupts the DNA of algae and microorganisms, preventing reproduction and gradually clearing green water.
Recommended Applications
- Koi ponds
- Ornamental ponds
- Nexus filtration systems
- Drum filters
- Moving bed systems
- Green water control
- Algae prevention systems
- Commercial koi systems
Installation Position
UV units should always be installed after filtration.
System layout:
Bottom drain → Mechanical filtration → Biological filtration → UV Clarifier → Pond return
