Product Description
Green water in a small pond? The OASE Vitronic 11 W is a compact UV‑C clarifier designed to control suspended algae and improve water clarity in smaller garden ponds.
It’s a simple, inline UV unit that works alongside your existing pump and filter system.
What It Does
The Vitronic 11 W exposes pond water to ultraviolet light as it passes through the unit. This process:
- Clumps single‑cell algae (green water)
- Allows your filter to remove the dead algae
- Improves overall water clarity
It supports filtration – it does not replace a mechanical or biological filter.
Key Features
- 11‑watt UV‑C lamp
- Compact, inline design
- Suitable for pump‑fed pond systems
- Designed for integration with standard hose connections
Ideal for smaller ornamental ponds where green water is the main concern.
How It Installs
Typical layout:
Pump → Vitronic 11 W → Filter → Return to pond
Installing the UV before the filter allows clumped algae to be captured efficiently.
Ensure correct hose sizing and secure connections to prevent leaks.
Maintenance
- Replace the UV‑C lamp annually to maintain performance
- Clean the quartz sleeve if limescale builds up
- Always unplug before opening the unit
- Never look directly at an operating UV‑C lamp
Regular maintenance keeps clarification consistent through the season.
Who It’s For
- Small ornamental garden ponds
- Ponds experiencing green water
- Pump‑fed filter systems
