CTUV-H10F

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.

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.

It was working really well honestly, but seemed like the motor or whatever stopped working. Lasted me about 2 months

I had an algae bloom pop up in my tank and I was skeptical of this product. Even after seeing positive reviews. I couldn’t hardly see through my tank the day I put it in (Sunday) and each day I saw improvement. Today it’s almost crystal clear after just 5 days of running it consecutively. My son added too much food this morning but the filter cleans the tank pretty well and keeps the water moving nicely.

This product is super and works great. I could see a change in about 3 days. But 7-10 days later it was clear as it could be. And its very quiet

Okay to be clear on this product, I am not paid for this review whatsoever. I see all the review discrepancies and this product is amazing but you have to have it perfectly in the right placement. This UV filter is a life saver for any tank, however, it’s quirky in the sense that it needs to be a specific level in your tank and with a specific amount of water levelization or it will stop working all together. You do have to play with the placement inside the tank (move it up and down a tinch) and play with your water levels (volume wise as adding more or less water to your tank) a little but it will come back to life 100 percent. Use an extension cord as well to allow more access to move it accordingly. When you do this— it works perfectly. The UV additions to my canister did not do the job this guy does.

This pump is a big larger than expected and barely fits into my small 10 gallon tank at an angle. It has to be completely submerged under the water or it will not work at all. Also the cord lengths are very short compared to my other cords (thermometer and led lamp) and there are two cords (the UV light and the pump itself). I was just expecting one plug. The flow is a little strong for my smaller fish and makes them swim backwards when resting but they don't seem to mind. And the sound is very quiet which is super nice. Overall, it really worked to get rid of my algae problem when nothing else did (including multiple water changes and algae water treatment drops). After 7 days my tank was no longer green but still a little cloudy. No change from day 7 onward (at about 3 weeks now). Overall I am happy it worked! Just wish the cord was longer and the size was a little smaller for my tank. Attached before and after photos.

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.

This isn't what you want for the price. Everything about it is cheap, cheap, cheap, and I doubt if it would pass CSA electrical compliance. The suction cup mount slides off way too easily, filter body below the motor falls off easily if not careful. The UV bulb has hairline cracks in it, and the wiring connections seem rather sketchy in my opinion. UV bulb is cheaply mounted in the unit. Unit has two power cords that are so short, they are useless and require extension cords if your outlet isnt right at the tank level. The cover on the powerhead always falls off ... it could have been so good and yet the cheaped out on everything

Very strong, so be careful where u place it in the tank. Other than that, it's great. Been using it for about 5 months. Easy to clean, comparatively speaking. Does a good job, and the UV does keep the bio residue down. I have a 40 gallon tank and I was finding that some were not oxygenating very good and I would end up with a gross tank. This works well.

I recently purchased a UV filter for my aquarium, and I couldn't be happier with the results! Within just three days, the water went from cloudy to crystal clear. It was incredible to see how quickly and effectively it worked. My fish seem healthier, and the overall appearance of the tank is much more vibrant now. The setup was straightforward, and the filter runs quietly, which is a huge plus. I highly recommend this UV filter to anyone struggling with cloudy water or algae issues—it's a total game changer!
