The TARARIUM Aquarium Filter U-V is a submersible internal filter designed for 20-75 gallon tanks, delivering a powerful 200 GPH flow combined with a 5W 254nm U-V light. Its dual-stage filtration system uses a biochemical sponge and U-V sterilization to rapidly clear cloudy and green water within a week, while separate switches allow independent control of pump and light. This filter not only enhances water clarity but also reduces odors, making it ideal for both freshwater and saltwater tanks, including turtle habitats.

EXTREMELY EFFECTIVE
THIS IS A REMARKABLE FILTER WITH A U-V LIGHT FOR AN AQUARIUM THAT IS HAVING TROUBLE WITH CLOUDY WATER. I WAS HAVING TROUBLE WITH BROWN ALGAE ( WHICH IS NOT A ALGAE AS SUCH ) AND WAS DESPERATE . I HAD TRIED EVERYTHING TO ALLEVIATE THIS PROBLEM SO I DECIDED TO TRY THIS FILTER AND THE RESULT HAS BEEN NOTHING SHORT OF MIRACULOUS. IT TOOK A COUPLE OF WEEKS AND I CLEANED THE FILTER ONCE, BUT NOW THE WATER IS SUPER CLEAR AND MY FISH ARE VERY HAPPY. I HAVE CAT FISH ONLY AND THEY CAN BE MESSY EATERS BUT THIS FILTER DOES A TREMENDOUS JOB. I DO A WATER CHANGE EVERY WEEKEND AND VACUUM THE GRAVEL AND I'M VERY HAPPY WITH THIS PRODUCT. I AM ALSO NOT OVER FEEDING MY FISH . I EVEN NOW HAVE ANOTHER BABY CATFISH WHO IS HAPPILY SWIMMING AROUND IN MY CLEAR TANK ! GREAT PRODUCT .

A great investment for any fish lover.
I’m impressed with how effective this aquarium filter is. Before using it, I had to change the water in my tank every two weeks to keep it clean. Now, thanks to this filter, I can go over a month without needing a water change. The water stays crystal clear and odor-free for much longer. One of the standout features is the built-in UV light, which helps kill harmful bacteria and keeps the tank environment much healthier for my fish. It’s quiet, powerful, and has made tank maintenance so much easier.

Stop Working after 6 months (2 units)
While this filter did great at keeping my tank clean, so much so I ended up purchasing two in May 2025. They only worked for about six months and then completely died. I cleaned them as I was supposed to took very good care of them., as they did such a great job, then out of no where they stopped working all together. I understand these aren’t top of the line but I anticipated getting a little more use out of these than six months. One other thing is if you have small fish such as guppies this is not a good filter. The smaller fish do tend to get sucked into the filter. So wow it initially did a great job. I was very disappointed with the longevity of the project and the fact that it ended up killing several of my fish. I’m still sold that UV filters by the way to go, but I will have to try a different brand as I was not impressed with this one

It really works!!
Excellent! Works as advertised and cleared a persistent algae bloom in a matter of days. Not overly loud or disruptive to the fish. Very pleased.
