Aqueon QuietFlow 20 LED PRO Aquarium Fish Tank Power Filter For Up To 30 Gallon Aquariums

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 only had the filter running for a few hours but I thought I would give Top Fin aquarium owners a heads up. The filter doesn't fit the Top Fin 29 gallon aquariums very well because the plastic rim is thicker then the filter is designed for. I had to shove extra filter padding between the rim and the spill over to keep the filter level and it elevated further then it should be but works. If you also have the lid that comes with the kit this creates a problem with water spilling out on the lid so I had to adjust the lid further forward so the water spills back into the tank. Filter works fine with my jerry rigging but Top Fin 29 gallon kit owners might want to give this filter a pass and look at other options. I'm primarily using it as a polishing filter since my biological filtration is an under gravel filter. I wanted a polishing filter with motor designed to sit below the water and no skimmer. A skimmer completely unneeded in my freshwater setup and can cause excessive noise when debris and floating plants get sucked into the skimmer. These filters run almost completely silent other then the flow of water sound. Self primes almost instantly within 3-5 seconds. My only complaint is it doesn't mesh well with the Top Fin 29 gallon aquarium and lid (that comes with the 29 gallon kit).

I have had just about every name brand filter out there. Been keeping fish for 30+ years. These filters are outstanding. They are quiet, dependable, have very strong suction. They have a telescopic (adjustable length) intake tube. Biogrids, an LED that accurately flashes when the gets clogged and needs to be changed (detects water level overflow), will NOT overflow if your media is clogged. Has a 2nd small chamber for either an ammonia reducer block, carbon block, or phosphate block. Pump is in the water so after a power outage they always start up. The design of the outflow keeps it gentle compared to similar filters. The 20 is good for up to 30 gallon tank. I own 4 of these filters. I have 2 on my 20 gallon and 2 on my 30 gallon. Can easily just buy a roll of floss and trim to size, don't need to buy the Aqueon replacement cartridges. I highly recommend!

I was apprehensive about buying this because of multiple reviews stating that it just stopped working & was garbage. As more of the reviews were positive and the price was right, I took a chance on it. & while this filter is a little more touchy than others that I've had, I've found that mine only needs is a little troubleshooting & servicing to get going again and I assume that some people who have had issues with it simply didn't know what to do. Easiest troubleshooting tip if it stops working is to make sure that the tank has enough water in it. The square motor housing must be partially submerged in order for it to work, so that the tube is all the say in the water. But that isn't usually the problem with mine, it's just the easiest. The usual culprit when mine stops working is that the motor needs some TLC and it's really easy enough to take care of. First unplug the filter & remove it from your tank. Unclip the motor housing from the filter body (clip is located under the water output shelf) and take it off. Plug it in & turn it upside down... most likely you'll see like a 3-cogged wheel not spinning; this probably means it needs cleaning. So take the bottom off of the motor housing. That should-be-spinny thing pulls right out, so go ahead & do it. The top part of that has a magnet & it may have some stuff on it, so wipe it off. The hole you pulled it out of may also have some stuff in it & I use a wet cotton swab to clean this out. That should be enough. To test it, I put the thingy back in the hole and put the bottom back on the motor housing and then plug it in. The wheel should spin again... it makes a weird sound if you have it upside-down to look & see if the wheel is indeed spinning, turn it back the way it would be if it was attached. If it stops making noise, great, but if it's still making loud noises, it probably needs a little lube. So take the bottom off again, pull out the spinny contraption again & put a little lube on the metal pin inside the hole. Put it back together & test it again. Hopefully I've solved any problems at this point... if not, you're having a problem that I haven't & I apologize for wasting your time going through these steps for nothing. ;) As for an actual review: it's a filter... it seems to do its job just fine. It is a little touchy, but I like that it can all be disassembled easily to clean it all out.

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've never left a bad review for a product until this one. My fishtank filter had gotten old after constant use so I purchased this filter and installed it properly.I was pleased with how quiet it was. I watched my fish for a few hours and they seemed happy although they seemed to be pushed around by the water much more than the old filter. I checked on them in the morning, fine still. Fast forward to today after work when I came in to check on them - only to find one of my poor fish stuck up against the filter tube. He was still 'blooping' but wasn't even fighting to get away. I turned off the filter and he just sort of floated away. It wasn't difficult to notice that half of his tailfin was gone. This filter sucked my fish against it and was so strong that not only could he not get away, the pressure sucked his tail off. There is only one use for this filter - to be put in a tank.. and yet, it is actually dangerous to the fish. You'd think with only one use, the maker would have made sure it's safe. Now my poor fish is just barely blooping around, mostly floating at the top of the tank. He cant swim around or even leave the surface of the tank. I am so upset that I bought this product and I am so upset about my poor fish and his impending death. :( I had to post this review so that people who love their fish will know to look elsewhere.

This filter works great in my 20 gallon high tank. My previous filter used a basket with separate sponge, charcoal pouch and filter media. To me, those may be great for some, but the simplicity of being able to change out the all in one piece filter wins by a mile. This does not include filter media of course, but I have driftwood to assist with maintaining beneficial bacteria. I also love the light on top that alerts me to let me know the filter needs to be changed. I’m no expert and I only have two tanks, but this filter is a great addition to my tank!

Works very well, I haven’t had this one for a long time yet, but my 40 gallon filter is the same and has worked for over a year and still holds up extremely well. Great product!!

Súper, es la segunda vez que la compro, tengo 2 peceras

I have never been so disappointed in an aquarium product. I purchased two of these filters, months apart, and both suffered identical, sudden pump failures. This is a clear and persistent design flaw. To make matters worse, the entire unit is disposable. When the filter cartridge is dirty, you are forced to buy a whole new unit—including another unreliable pump. This is a wasteful and expensive cycle. A product that fails at its primary function (pumping water) and then forces you to re-purchase its own flawed design is unacceptable. I strongly urge you to look for a more reliable and sustainable option. A complete letdown.

Love this filter, I used it in addition to my Fluval canister filter to help keep my tank clean, create surface disruption and some aeration in my 75 gallon. I used to use one like it, on its own in my 30 balloon also worked well for that tank size as the only filter.

No tengo quejas, filtro fáciles de cambiar siempre que puedas comprar el reemplazo

Initially worked well but stopped working very quickly. Looks like it's a 110 volts pump that is sold in Dubai where electricity is 220 volts. Not recommended for UAE users.
