Review on High-performance OXYFUL 55W UV Light Clarifier Lamp Filter 🐠 for Aquariums, Koi Ponds, and Fish Tanks - Non-Submersible, 27-inch by Sandra Goode

I have had several ponds over the years and although the water has always been good I have never had clean water. After spending thousands of dollars on chemicals over the years, I decided to give it a try. It's awesome! I will say it took me months to run 24/7 but I can finally see the bottom of my pond where before I could only see about a foot below. I have a 7500 gallon pond, up to 4 feet deep, with 7 medium to large sized koi, a skimmer and a waterfall. I put a 2x6 on it to protect it from the rain. I am very happy with this purchase!
