24W 10,566 Gallons Aquariums & Ponds UV Light Clarifier – Non Submersible Ultraviolet Lamp Filter for Koi Ponds, Fish Tanks, Pools & Spas – Powerful Water Purifier

Wow!! What a difference this made in our goldfish pond. After comparing other models and reading reviews this one is it! Our pond is in sun all day. It cleared our murky pond within 5 days. Now you can see all the way to the bottom of our 3 foot pond. The product is also very well made and sturdy.

The media could not be loaded. Fantastic sterilizer We have a BIG pond and in 3 days it was clean. It was green and starting to stink. Yes i would recommend this sterilizer. Pond size is 2500 gallons. Its built sturdy and looks to be durable for years to come.

Improved UV light is way easier and much less expensive than previous generations of inline nonsubmersable UV algae killers.

It took care of suspended agile, but we are still dealing with filamentous string agile. I am not disappointed with the results though. We live in the North West and have a 2,000 gallon goldfish pond that uses a 1/3 Hp high flow pump from a company in Portland. The "Algaefix" works too well, almost, and cuts of oxygen, yet this thing seems to keep things in check between treatments.The UV tube it comes with is really cheep and only lasted 2 months. The electronic power head was not the problem, we had to get a new UV tube. All was good after that. The plastic and seals are holding up just fine.

Had the unit running for less then a yr and decided to take down the tank. Whe. I opened it to see what shape it was in. There was rust everywhere. Wish I never used this light cause I'm sure now it was the downfall of my tank. You can imagine nothing was living.

After researching UV-C lights for swimming pool Maintenace I bought this one for an 8000 gallon pool. (This is the same design and lamp type sold at pool supply stores for 3 to 4 times the cost.) I bought it in spring of 2019 and have used it every day 12 months of the year since. Replaced the lamp once. I just bought my second one as the main body after three years has developed a length wise crack and a small leak. It did take a bit of ingenuity to adapt the fittings to my pools plumbing. Great value for investment

I have a 350 gallon pond with plants, and 6 fish. This light runs in line and keeps my pond water crystal clear. I have it set to a photosensor timer that keeps it on for 6 hrs a day with my pond lights. Comes with all fittings you would need for I think 3/4 inch all the way to 1.5 inch tubing. Plug and play and very heavy duty. This is not a submersible fixture as you may already know. I did have one fail after a week, I think it came in defective from shipping. Emailed through Amazon and had another light in 4 to 5 days without having to send back my old one. Just sent a few pics and told them the problem. Hassle free and good service. Highly recommend!

I've had a few ponds over the years and while the water always tested fine, I never had clear water. After spending thousands of dollars on chemicals over the years, I decided to give this a try. I'ts fantastic! I will say, running 24 hrs a day, it took a few months to clear but I can finally see the bottom of my pond where as before I could only see about a foot down. I have a 7500 gallon pond, up to 4 ft deep with 7 medium to large Koi, a skimmer and falls. I do have a 2x6 laying over the top of it to keep most of the rain off of it. I am very pleased with this purchase!
