The light is doing a really awesome job cleaning up the water. My water was a little unclear and after 6 days of running it, i can see the bottom of my pond and all my fish. Absolutely love it. Would definitely recommend. Pic I posted has been after 6 days, so I still have a little ways to go but I figure in about 3 more days it will be completely clear. I do have mine outside the pond due to pipe that was already set.
