Why Choose UVPond
Clear Green Water Fast
Tired of looking at a murky, green pond or fish tank? The UVPond 9W Inline Pond UV Steriliser is engineered to clump together microscopic suspended algae, allowing your existing mechanical filter to easily extract it. Within days, you'll notice a dramatic improvement in water clarity, ensuring a healthier environment for your koi, goldfish, or tropical fish.
Versatile Dual-Use Design
Unlike single-application units from competitors, our 9W uv steriliser is built for versatility. It serves brilliantly as a fish pond uv clarifier for outdoor setups up to 4,000 litres, whilst its compact footprint makes it an equally effective external aquarium uv steriliser for indoor tanks up to 400 litres. It's the perfect standalone upgrade for hobbyists who want clearer water without replacing their entire filtration system.
Simple, Universal Installation
We've designed this inline pond uv clarifier to be as user-friendly as possible. Supplied with universal stepped hosetails (accommodating 12mm, 16mm, 20mm, and 25mm hosing) and a generous 5-metre cable with a standard UK 3-pin plug, integrating it into your current pump and filter circuit is straightforward and stress-free.

Customer Reviews
I bought this to use as an aquarium uv steriliser for my 300L planted tank. It cleared up a persistent green water bloom in just 4 days. Very impressed with the build quality.
Next day delivery was spot on. Fitted this inline pond uv clarifier to my 3000L goldfish pond easily using the supplied stepped tails. Water is crystal clear again.
As an aquatic biologist, I appreciate a well-designed UV unit. The quartz sleeve is high quality, and the 9W output is perfectly calibrated for smaller setups. Excellent piece of kit.
Great little 9w uv steriliser that does exactly what it says on the tin. My only minor gripe is that a 7m cable would have been slightly better for my specific garden layout, but 5m is standard.
Much better value than the Hozelock or Pontec equivalents I was looking at. It feels sturdy, was easy to install, and cleared my green water pond issue in under a week.
Using it as an external aquarium uv steriliser. It is slightly bulky inside my aquarium cabinet, but it works flawlessly and the stepped hosetails made plumbing it into my canister filter a breeze.
Fantastic fish pond uv clarifier for the price. I didn't want to buy a whole new filter box, so adding this inline unit was the perfect, cost-effective solution for my wildlife pond.
