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

Always had an algae issue with my hundred gallon tank, added it to the filtration system and now my algae issue has cleared up.Had to get some extra fittings because the hose sizes between my filter and the UV light were very different. I also sealed each connection with aquarium grade silicon.

Set up a new goldfish pond last year and could never get rid of green algae, causing alot of frustration in watching and enjoying my fish. Pond is 6' x 10' and no amount of algaecide helped. Bought this UV filter after opening my pond this year and seeing more algae blooms. I work in the industrial "water business", so very familiar with UV technology. I intentionally bought a unit oversized for my pond, as I get direct sunlight almost all day and it was the right move! Green algae bloom was gone in a week and after 4 weeks, the water is clear enough to see to the bottom and getting better every day. Best suggestion for others - DON'T UNDERSIZE! (and match your pump flow to the UV size). Wish I would have done this sooner!

Have had it running for a week and so far im seeing results. I would advise to put it on a timer.

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.

This is one of the best clarifier! The only thing is that hoses are measured in ID not OD. So, the hoses you need are 1" ID, 1 1/4" ID or 1 1/2" ID. The 1" ID fits perfectly. Update...... After about 9 months, the transformer blew!Worked while it lasted but did not even last a year!Not worth the $$$$

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!

It cleared up most of the algae in my pond in just a few days! I was really happy to not see green!

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.
