Works great, it will take a couple of weeks to clear the algae but I can tell a big difference.

I was excited about this product because of the great reviews. It's been installed in my pond for 6 weeks and i don't see the water quality improving. I thought maybe it's defective but, the light is on and water flows thru like it's supposed to.

I have tried everything under the sun to clean 1100 gallon pond with gold fish. This is the first thing that has ever worked. You can see 3 feet to the bottom and all of the fish. Pond and waterfall have never looked this good!
