TARARIUM Small Aquarium Filter U-V for 10-45 Gallon Tank, 158GPH Fish Tank Filters for Betta Fish Tank Green Clean Machine, Internal Pump Filter for Turtle Tank Saltwater Freshwater Crystal Clear

I have a 75 Gallon Cichlid tank. I started from scratch with setting everything up and I had never had such a hard time with cycling before this tank. Cichlids are dirty fish. This product is AMAZING. Not only does it clear up the water, but it aerates the water very well! It’s definitely worth the money. It’s no more noisy than a regular bubbler and all I had to do to install it was screw the top, submerge it, and plug it in. The pictures are from day 1 and day 4.

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 .

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.

So initially I installed this in my son's 10 gallon fish tank. It had WAY too powerful filtration...if you look it has a 10 watt pump which is in the range of 200gph filtration. So I took it out and went back to the hang on the tank filter. With 2 goldfish and 2 minnows in a 10 gallon tank, I eventually had an algae problem. I was replacing HOB filters clogged with algae every couple days and the water was still murky and algae out of control! I really didn't want to resort to chemical algecide on account of a fish kill incident early on in my learning about fish tanks. So I adapted some irrigation hose to make a diffuser for this pump's output and removed the sponge inlet filter (not recommended) just to see if the UV could help. I had it on for about 1/2 hour, and the fish were constantly freaking out. Also, I noticed the water had become more cloudy with lots of micro bubbles (Ozone?). I turned it off to calms the fish and just went back to depending on the HOB filter. Well, that was Friday, and watching the tank over the past couple days wondering what to do it has progressively gotten clearer like magic. Today (Sunday night) the water is crystal clear!! I think that in the 1/2 hour this filter ran, the UV light directly sterilized or added enough Ozone to completely kill the algae. Amazing! So for the videos that show how clear it gets over a few days.....it MIGHT actually do that even if it only runs for a little bit on day 1..... the rest may be overkill....in any case, extremely effective.

It worked great. Much easier to deal with, and cheaper than the Green Killing Machine. I am trying to research how to change the UV bulb when I need to though, and I'm a little confused about that. Recommended.
