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.
