    I actually bought this filter in the used/refurbish section on Amazon after months of searching for the right filter for my new aquarium, 10 gallon tank. Despite I bought it used this filter work like a charm! Here is a mini breakdown:

    Performance: Powerful. The pump was so strong that I ended up making a baffled to restrict some of the water flow but even then the water can be seen rippling through the surface. Not only is the pump strong but it is quiet as well, really live up to its name “QuietFlow”. Occasionally some small water dripping and humming from the motor can be heard but you have to be right in front of the tank to notice it. This filter is also self priming, which mean that you do not have to pour water in the filter to get the filter to work and move the water flow. I found this a bonus, since I always unpluged my filter to do water changes. And every time without a failure when I plug it back in, the filter just automatically do its job and within seconds, water is already pouring out and silently too!

    Design: Bulky but functional. Its looks a bit big but will fit quiet nicely on the glass panel without any falling or sliding problem. If you have a 10 gallon tank with a standard hood, the 20 or 10 version will fit on the tank with the hood on just fine as well. The intake tube is adjustable meaning you can slide it up/down. Inside the filter there is some room for additional filter medias beside the one it originally come with. There is also 2 plastic meshes that help with aerating the water (you can see it in the picture, it is the blue thing) and store the beneficial bacteria. There is also a resting place on the side of the filter for the cord so it wont be hanging out unnecessary in your tank. Additionally, all parts on the filter including the propeller, and intake tube can be taken out and clean or wash if necessary.

    Con: Unfortunately with everything there has to be a drawback. The problem however, are really small and aren’t really consider much of a nuisance. I found that the cover/cap of the filter do shake sometimes, especially when you open it and don’t close it properly. This created a very loud rattling noise, which can be easily fix by closing it properly or use a rubber band to bind it securely down. Another thing was since the pump is so strong, it would be nice to have an adjustable option to restrict the water flow, but sadly there is none.

    A tip: If you decided to have live plants in your aquarium that have spiky leaves, especially the Hornwort, the falling leaves can get suck up by the filter and create a blockage overtime. So monitor this.
    Overall I have had this filter for over 3 months now and it is still going strong and keeping my aquarium super clean without any problem. I couldn’t be happier with this filter.

    I have a tank with a large number of fish (around 20 fish total, plus around 40 shrimp). To give the bacteria enough filter surface, I have been experimenting with different filter types and configurations. I owned a canister filter (under the aquarium), gave up on that and switched to these hanging filter types. I bought and used 3 Aqueon QuietFlow filters: 50, 10 and 20. The 20 is my favorite! The flow of the 50 is too high and it is a lot noisier than others. Also, because of the high flow, the filter in the 50 needs to be replaced very often. 10 is quiet, but has a “medium” size filter pad, which is way too small for anything more than 2-3 fish. The 20 is my favorite – it is very quiet, the flow is good without making the fish struggle against the current, and it uses a large filter element, the same as 30 and 50. If you have an aquarium, I recommend getting 2 of Aqueon QuietFlow 20 filters and using them in parallel instead of getting one QuietFlow 50. You will get twice as much filter surface, a back-up for failures and will need to replace the filter pads a lot less frequently than in other filter models.

    I got a tetra 20 gallon high aquarium and the filter fits perfectly. I did get a foam tip to wrap around the intake so nobody gets stuck. It runs perfectly, and it is truly quiet. I got it to replace a whisper that was painfully loud. This is for my bedroom tank, so I need real quiet. It has its own ambiance that is soft. I’m very pleased!

    The filter is OK but I didn’t realize it doesn’t have a water flow adjustment. It a bit too strong of a flow for my 20 gallon tank.
