Help and advice on shopping for: Pond UV Clarifiers
How does a UV Clarifier work?
Pond clarifiers use ultraviolet light to combat green water caused by free-floating algae. Pond water is pumped through the chamber and is exposed to UV light, which damages the algae and causes it to form clumps. These clumps are then caught by your filter, leaving your pond clear.

Frequently Asked Questions
Which is the best pond UV clarifier?
Choosing the right model for a clear pond depends on your pond's size, sun exposure, and filtration setup. Our range includes top-rated options that cater to various pond sizes and budgets.
When selecting the right model for your pond, you will need to consider the following:
- Pond Volume: Larger ponds require a high wattage to effectively treat a large amount of water.
- Algae Issues: If you're experiencing consistent green water, a higher output or longer exposure chamber will provide the best results.
- Livestock: Heavily stocked fish ponds often need powerful clarifiers to maintain healthy conditions.
Whether you're needing a small unit for an ornamental pond, or a high wattage model for a Koi Pond, there's a model tailored for your needs. Check out our help guide here for more details.
Is a UV clarifier the same as a UV steriliser?
No, an ultra violet clarifier controls algae and prevents green water, whereas a UV steriliser has a stronger UV to kill harmful bacteria, parasites and viruses.
How long should I run my UV clarifier?
It is recommended to leave it running 24/7 during March-September when algae growth is stronger and faster, allowing for effective treatment when you need it most.
How do I install a pond UV clarifier?
This depends on your model, but for most inline clarifiers you will need to install it after the pump and before biological filtration, so that algae is killed before the water is treated. Attach your pond hose from the pump to the unit, and then from the unit to the pond filter, ensuring a watertight seal.
Maintenance is simple with most models, allowing for a simple change of bulb whenever required. Check out our detailed guide on changing your UV bulb here.
