Green pond water? Enjoy clearer water without adding chemical algae treatments.
Restore clarity to your garden pond with the Bioscape Terminator UV Pond Water Clarifier, a high-performance ultraviolet water treatment system designed to control free-floating algae responsible for green and cloudy pond water.
Whether you're maintaining a small backyard pond, a koi or goldfish pond, a decorative water feature or a larger aquatic garden, the Bioscape Terminator range offers a practical solution for managing suspended algae.
Available in four wattages — 11W, 18W, 36W and 55W — the range caters to different pond volumes and circulation requirements, with manufacturer-rated capacities extending up to 37,000 litres for ponds without fish.
Simply select the wattage that suits your pond or water circulation system.
How Does a UV Pond Water Clarifier Work?
Green pond water is often caused by microscopic, free-floating algae that multiply when sunlight, nutrients and water temperatures create favourable conditions.
Unlike chemical algae treatments, the Bioscape Terminator uses UV-C light to target suspended algae as water passes through the clarifier.
Water is pumped through an enclosed chamber containing a UV-C lamp protected by a quartz glass sleeve.
Exposure to UV-C light damages the algae cells, helping them aggregate into particles that can be captured by the pond's mechanical filtration system.
This process helps improve water clarity without introducing chemical algaecides into the pond.
The result is a practical, non-chemical approach to green pond water management.
