User Ratings and Reviews

5 Stars I was amazed at the results
My backyard pond has always given me trouble with severe algae. I would clean it out and the next day it was green again. I could never enjoy my fish, and many were even dying. A local pond builder recommended I try a UV light as a last resort. I did lots of research online looking for the best one, since I knew nothing about UV lights. All the reviews I read on the Pondmaster UV light were good, and it seemed like a well-built product. I liked the idea of being able to use it in or out of the water. The only question I couldn't find an answer to was how to actually set it up in my pond with my pump and waterfall. I finally found a website with some help, but I would have been more confident in buying if I had more information on installation. When I received the product I found it was very easy to assemble and install. After 4 days my pond went from deep green to pale gray, then each day it got more and more clear. After about one week my pond is clear and I am enjoying watching my fish again. I would strongly recommend this product to any pond owner. It was so easy to install, and has cut my pond maintenance down significantly. No more dumping algaecides and clarifiers in with my fish either.

3 Stars It Works But.....
I bought a 20W bulb for ~2000 gallon pond. It has been running a couple of weeks and the water is clearer, but not clear. Perhaps the bulb included was not up to par. My biggest beef is that the enclosed set up diagram was completely wrong. You will need to attach a 3/4" fitting on the light housing to the 1" inside diameter of the 1 1/4" hose from a typical pond pump. You will need two sets of 3/4" to 1" nalgene fittings and two-3/4" and two-1" hose clamps.

1 Star ultra vilot light
The light was ok but they don't tell you that you need other parts to go with it and there are no instructions at all. They don't tell you were to place it or how to place it. I was very disappointed with that. Therefore I returned it. The return was not a problem.
