hygger 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

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.

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.

I was initially hopeful about the hygger 3-in-1 Aquarium Filter due to its multifunctionality and compact design. However, my experience has been disappointing. After just a few weeks of use, the pump ceased functioning entirely, rendering the filter useless. This failure not only disrupted the filtration process but also compromised the oxygenation and circulation features that are vital for maintaining a healthy aquarium environment.​ Pros: Compact Design: The filter's design is space-saving and fits well in smaller tanks.​ Pretty quiet Cons: Pump Failure: The pump stopped working after only a few weeks, leading to a complete loss of filtration, oxygenation, and circulation functions.​ Reliability Issues: Such an early malfunction raises concerns about the overall durability and quality of the product.​ While the concept of a 3-in-1 filter is appealing, the hygger Aquarium Filter fell short in terms of reliability. A pump failure so soon after purchase is unacceptable, and I cannot recommend this product to fellow aquarium enthusiasts seeking dependable filtration solutions.

Compact filter. Easy to assemble and clean. However, it just stopped. After two months of use. Cannot figure out the reason. I am a huge fan of hygger products. Think this one just happened to be defective.

Love that this is a submersible filter that adds oxygen to the water! The waterfall function is nice, but our tanks are in the living room so I prefer not to hear running water 😉 Easy to take apart to clean too.

This was a fantastic filter for our little 2.5 or 3 gallon tank. Slightly powerful for the little beta fish we have but manageable enough for the little guy. Now, where can I buy the replacement media?
