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!

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.

This is my favorite brand of hang over back filter, because it starts on its own after a power failure! I ended up getting one for each of my tanks because of this! You don’t have to pour water into it repeatedly to get started like some other models. My unit arrived in perfect shape thankfully. There’s a bit of a design issue with the plastic being quite thin. The housing for the impeller is held on by plastic clasps which over time can weaken and break off, that’s what happened to my old unit but I’m still using it!

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