Customers say
Customers find the UV filter effective at making water crystal clear and clearing tanks within a week, considering it well worth the money. The water flow receives mixed feedback, with some praising its powerful performance while others note it’s not adjustable. The functionality, quality, and algae control aspects also receive mixed reviews, with some reporting it works great while others say it doesn’t do as advertised, and some finding it of good quality while others describe it as low quality. The lifespan is concerning, with several customers reporting that the light broke.

So far so goodâ¦
I was excited to use this because I had a lot of green algae bloom in my 50 gal tank. I was happy to find out my UV light works as other reviews mention that sometimes is was defective. The filter has a small indicator so you can tell if the light is on. There are two power cords, one for the filter and one for the light that has a switch on it. The sponge filter at the bottom does a great job at picking up small debris and keeping small fish safe. It has a very powerful water flow and circulates a lot of water in my tank. The filter has many different sections, making it easier to clean. So far Iâve had no problems with the filter itself or the light and itâs been 2+ months. It includes an air hose which seems flimsy but works and you donât have to hook it up to an air pump, it pulls in the air as long as itâs above the water.Downsides:Not long after I set this up, I noticed lots of white hair algae was growing on the wall of the tank where the filter outlet was pushing water. And the water flow was significantly reduced. I cleaned it and found more algae inside, not any green algae though. After a few weeks of cleaning and algae treatment, there has been less algae bloom and the filter has needed less frequent cleanings.Overall:This is pretty tall, fits in my taller 50 gallon tank. Great price, and looks like it will last. Would recommend using this if you have serious green algae bloom, and especially if you pair it with a chemical algae treatment.The filter has a indicator so you know if the light is on and the cord for the light has a switch to turn it on or off. Easy to install and use. Very quiet as itâs a submersible pump.

Amazing Change and results for my fish pond!!!!
This is an amazing product! I didnât think anything would help with my green water from my little 40 gallon outdoor goldfish pond! This product did! If only the backing with the suction cups worked better with my Rubbermaid type of pond, but I didnât dock stars for thatâ¦I balanced it on a rock and itâs just fine! It took 3 days and voilà !!! Clear water and I can see the fishyâs again! Thank you!!! I didnât think it would work since you canât see the actual UV light! Just the little light indicating itâs on! I didnât even have to run my other pump, just this one! Pics to show difference are attached. I never leave reviews hardly ever but had to for this product! Iâm so happy!! Thank you! I am going to have it on 2-4 hours daily for maintenance now.

Great for 150 gallon turtle tub!
Easy to install, clean, and use. We have ours in a timer for 6 hours a day and it easily keeps our turtle tub (150gallon of water) clean for the week between water changes. Moves water really well, my slider turtles love the ripple waves it produces. Compact. Better than higher priced models we have tried.

Stopped working.
Itâs a few days past 30 days and the uv light no longer works. I have only used it on about 6 occasions running for approximately 1-2 hours. I hope the seller can help.

The electrical cord broke while in the water.
That little filter/UV light has been great for the two years that Iâve had it. Thank God they make these the way that they do seeings how this cord broke while it was in the tank with my fish and I put my hands in there to clean this.It is quiet it works great. Only complaint is that this cord broke.. I didnât even know it until I pulled it out of the tank to clean it.

WORKS FANTASTIC!!!!!
This thing works like a charm! The first photo was when I first put it in the tank. The photos are 2 weeks apart. I did see a significant change within a couple days, but now itâs CLEAR! The size was a little bigger than anticipated but fits well in my 55 gallon. The outflow of water is adjustable as well. I have it set pretty low because I have some small fish and shrimp in there. So it might have cleared things up a bit faster had I had it wide open. It also has 2 plug ins. One just for the UV light (which also has an on/off switch) and one for the filter. I strongly recommend this uv light if youâre struggling with unclear water!

Green water killer
The uv light with filter are working fine, the unit size makes me happy , the body is very skinny save my tank size, green water are remove very quickly in my case it only take about 1 and half day to rip the green, easy install, easy to take care and clean the pre filter sponge, noise not loud but it dose making sounds, only one I donât like was there are no uv light timing control , this very no convenient, I have to use my own timer switch
