Review: Really does get rid of green algae - Every year I get a problem with a type of algae that grows over everything and so far can find little that touches it, but I also get a problem with single celled green algae that this year literally turned my koi pond into pea soup. I've tried numerous "chemical/biological" treatments and none have worked, these frequently have had mainly five star reviews saying how they have produced crystal clear water yet plainly these have been fake reviews since I've found just like all those who gave them one star that they were useless. So I started looking at UV as a solution and once again I was faced with numerous 5 star reviews stating how good it was and then one star ones saying how useless it was, although I have to say some of these negative reviews weren't necessarily regarding green algae. I was also rather sceptical since my pond filter has a built in UV lamp and that plainly wasn't sorting the issue. Further research showed that my in built lamp was to sterilise the water leaving the filter so obviously wasn't a green algae solution. I decided I needed an extra inline UV lamp before the filter and picked this one since it was close to my flow rate but allowed some wriggle room to make sure it wasn't trying to work on a wrong flow rate. Now this is where it's going to start sounding like a fake review but literally within 24 it really did look like the water was clearing, not a lot but definitely better. Within days it was obviously working and the water was looking clearer! We are now into the third week since I fitted it and the pond is almost clear of the green algae. Do not buy this for anything other than getting rid of green algae, it only has an impact on algae but unfortunately despite it being advertised as this use and this use only some buyers have bought it for brown or other types of water and then given it negative reviews for not working. I only wish I'd taken a before and after picture but I never imagined it would firstly work this quick or secondly work this well. So to repeat if you have a problem with green algae get one of these (make sure you get one suited to your pump) it really really does work!

### ⭐⭐⭐⭐ First impressions - Good.
*by G***N on 14 June 2025*

Read the manual before buying. The Ballast is roughly 1m from the end of the cable, so shortening the cable is not possible. The device draws 29.5W, according to my wattmeter, during testing, and the ballast becomes mildly warm. The unit has its I/O in multiple directions, so do consider where it is to go. The Ballast is also reasonably large. The unit is elementary to put together and didn't leak - good. I will update the review in a week or so and comment on the water clarity. The viewports are useless in a UK summer sun. I will try them again later tonight. The best part by far is the transparent hose tail with the spinning propeller inside, showing water flow. Update 2 weeks later. My small 1000L pond is now crystal clear after being green for years. Fustratingly, I also a month ago improved by mechanical filtering, so this is not a scientific test.
