AquaMiracle Aquarium Filter for Green Water, U - V Fish Tank Filter with Timer (4/8/12/24 Hrs), Dual Mode (Aeration/Rainfall) Fish Filter for 10-40 Gallon Tanks, Flow Rate and Direction Adjustable

I was initially skeptical about purchasing this product after seeing it listed as a frequently returned item on Amazon. However, I was desperate for a solution to the algae problem in my aquarium. I set the timer for 12 hours and left it overnight. To my surprise, when I checked the tank the next evening, the water was nearly crystal clear!This is a 10-gallon planted shrimp tank, and I’d say about 99% of the algae was gone. I was genuinely impressed and happy with the results. I didn’t experience any issues during operation, although I did notice the switch control box was slightly warm to the touch. I’ll continue to monitor that and update if needed.Overall, I’m extremely satisfied with this purchase and happy to leave a positive review.

Took some patience but it does work to get rid of algae. It’s a little annoying to clean the sponges every water change but what’s important is it works.Would be very helpful if there was an indicator showing when the UV is on and another to show when the bulb is out and needs to be replaced

I was very excited to use this filter as I have had some serious green water from cycling my tanks. I gave it some time (20 days) before leaving a negative review. I could've just got a bad product but the light is clearly working, the watts its producing... im not sure becauae the light it self didn't seem all that strong. I was only using this filter for 10 gallon tanks which you would think it would be over kill as its the lowest rated tank this filter is recommended for. I covered one of my tank in a black garbage bag, and I used this filter in the other by day 7 the black garbage bag has cleared up way more than this filter. After 2 weeks no result the water is even greener than before. I tried adjusting the pressure higher and lower still, no change. I finnaly gave up on this product and all the praise it recived from some previous review 3w is clearly not enough to remove green water from a ten gallon. Good luck if your trying to try this item but I was disappointed.

I had been battling an algae bloom for months and no matter the cleaning and treatments, it would just not stop. I came across this pump with UV and it looked like the perfect solution to get ahead of the infestation. Installation was easy enough though the riser for the water return is quite short requiring the pump to sit just below the water's surface not far from the minimum level. It would be nice to have the pump closer to the bottom where the waste sits but then you've got to use the noisy air siphon. So, one, two, three days passed and conditions had not improved with the UV set to 24 hours; in fact, things were worse. The only way I was able to get some inkling of control was to leave the tank dark for three days. At this point in time the UV is just barely holding the algae at bay even when set at 24 hours. I previously tossed my algae covered plants and hoping adding new ones will help control the last bit that the filter is unable to eradicate.

Very easy to setup. Cleared water in a day!

Worked well but only for a few months. I thought the light bulb blew but I bought the replacement bulb and it still does not work. There are other reviews here that state the same.
