CTUV-H10F

I’m really happy with this aquarium filter. It was easy to install and started working right away. The water in my tank cleared up noticeably within a day or two, and it runs fairly quietly compared to other filters I’ve used. I also like that it has the built-in UV feature to help keep the water clean. Overall it works great for my tank and seems like a good value for the price

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’s magic! I had set up a stink bug trap close to this tank and had no idea it was causing an enormous algae bloom. I thought this was just a UV light but it’s actually a filter, too. After seeing how great it works I’m considering buying one for all of my tanks!

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

Very powerful. Mounts easily good build quality. I did cut the foam filter and add in some ceramic media to support a good ecosystem. The uv algae killer is no joke. I put this in a dirty green tank just to see if It could clean it. It stopped the growth cold and cleared the water in less than 24 hours (it was very very murky) I now understand why the uv light is separately controlled from the filter as it would kill too much algae if left on. I like to leave a little for the snails to munch I have it in a little tank and it is a little loud but thats due to the depth.

This is a great product. My water was foggy before I got this product. 3 days later the water is super clear. The pump is really strong, so I purchased a sponge and cut it in half and zip tied it to the nozzle and it worked perfectly.

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 .

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.

I had a previous version of this and bought a second so called improved. The UV light is difficult to get in place, the bottom of it, which you are blindly putting in, and has to be exactly in the right spot. The sponge filter will need regular cleaning so clumsiness of this is a regular inconvenience. The friction fit of the top to the bottom means you will need to carefully arrange this in the tank or the bottom could fall off? The inlet for the air hose is again a friction fit, and so loose it does not stay in place. And lastly, the air hose they provided is so flimsy it's got kinks, and pinches in it even from shipping. It was frustrating to put together so from an ongoing maintenance point of view it's just not usable IMHO.

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.

My tank was very cloudy, within 24 hours it was crystal clear. The smell is gone too!
