Aquarium Filter DC 5V Multiple Function Power Quiet Fish Tank Filter with Rainfall Aeration 3-Stages Filtration Adjustable Submersible Internal Fish Filter for 2-13 Gallon Small Tank

Purchased the 5w version. This is hands down the BEST filter I have ever tried... and I have tried a LOT! DC motor removes the 50hz AC mains hum. 2mm piece of air line tubing over the shaft for the impeller to ride on and a small dab of petroleum jelly\Vaseline on the impeller shaft and it's absolutely silent. Tank is 6t from my head in the room where I sleep and even at 3am in absolute silence I can't hear it. Honestly cannot recommend enough, from no on I'm only using these filters.

I have two tanks: a 20 tall and a 40 breeder. I had an issue with the one for the 20 tall a couple months in and Hygger sent me another one right away - and that one's working perfectly. I love that the 3 chambers can be replaced/moved around/customized if you'd like a different media in them. The options for the output are great. I personally prefer the rain drop option - which aerates my water perfectly without adding an air pump, gives nice visuals, and stimulates breeding in some fish. The chambers are see through - you can actually see the beneficial bacteria on the media balls. Cleaning and care is simple and easy. The pump itself is quiet (at first it wasn't, but then I realized there was air trapped in it. I turned the filter upside down to let the air escape and it's been perfect since then). All-in-all, I don't see myself getting a different filter for a beginner-mid level hobby tank.

I purchased this for my mom who is a senior because she wanted something that was quite and of good quality. Reading the reviews we were excited thinking this would be a good purchase. IT ISN"T. It makes an on and off grinding noise which keeps my mom up at night. Very disappointed.

Really liked the idea of this filter and it was great when I first set it up, but within a month it jammed up. I cleaned it out and was able to get it working again, but after another few weeks it died completely so I’m back to my ancient whisper from two decades ago that continues to limp along. Cool idea, didn’t last.

Great little filter worked great in my tank

I've had such a hard time finding the right filter and pump, but this one finally does the job. I have a unique setup where my tank is under hanging cabinets, and my last two purchases didn't fit properly because they extended way too high over the rim of the tank. Another issue with the others were that they all sat ON the rim and therefore moved quite a bit when i needed to pull the tank out. I love that this is submersible and you can remove one of the filter boxes for a lower water level tank as well. Even with only two of the filters being used it's working perfectly on my 20 gallon long. I've only had to clean it once so far and it was an easy task. I don't find it to be loud and enjoy the sound of the rain attachment. To the last point, being able to lower the arm even more is a great feature as well.
