Product Description
Large ponds and high flow rates need serious UV performance. The OASE Bitron Eco 120 W delivers powerful UV‑C clarification while maintaining energy-conscious operation, making it suitable for demanding garden and koi pond systems.
It is designed to integrate into pump‑fed filtration setups and work alongside a properly sized mechanical and biological filter.
What It Does
Green water is caused by microscopic single‑cell algae suspended in the pond. As water flows through the Bitron Eco housing, it is exposed to UV‑C light.
The ultraviolet treatment:
- Disrupts suspended algae
- Causes algae cells to clump together
- Allows your mechanical filter to capture and remove the debris
UV‑C treats the algae. Your filter removes the waste.
Designed for Larger Systems
The 120‑watt output is suited to:
- Large ornamental ponds
- Koi ponds with higher stocking levels
- Systems running higher flow rates
Correct sizing depends on pond volume and pump performance.
Installation Layout
Designed for inline use in pump‑fed systems.
Typical setup:
Pump → Bitron Eco 120 W → Filter → Return to pond
Positioning the UV before the filter ensures treated algae are removed efficiently.
Maintenance & Safety
UV‑C performance reduces over time, even if the lamp still appears lit.
- Replace the UV‑C lamp as recommended to maintain output
- Clean the quartz sleeve regularly to prevent limescale build‑up
- Always unplug before opening the unit
- Never look directly at an operating UV‑C lamp
- Avoid skin exposure to UV light
Routine maintenance keeps clarification strong during peak algae season.
