It works great to keep my fish safe and healthy!
No more green water!
This UV filter is really powerful. I’m using it on my 450-gallon outdoor pond, and it does the job very well.
One thing to note—be careful during installation. The light is strong, so wearing sunglasses is a good idea to protect your eyes.
I also like that it sinks, which makes it easy to place at the bottom of the pond. Setup was simple, both in an aquarium and in the pond. Just keep it away from anything live. Overall, it’s a solid product, a good value for the price, and a great addition to my filtration system.
This light is very well made. I believe I have seen a difference in the water clarity.
The self-sinking design, the strong glass surround pipe, the waterproof wire connection, this is an all-around great UV lamp assembly.
