Aquarium Hang On Filter Small Fish Tank Hanging Filter Power Waterfall Filtration System

Truth be told I was concerned about getting this HOB filter for my 2.5 gallon shrimp tank due to some critical points other reviewers made. So you know where I'm coming from, I do have a larger 30 Gal general tank and I've typically had bad experiences with HOB tanks that have the pump outside the of the tank. I tend to do better with either "self-priming" HOBs or Internal filters. However, for a 2.5 Gallon tank, internals take up too much space for the aquascaping I wanted to do and the only "self-prime" HOB I could think of that would fit was no longer produced (Marina S5). So I had no choice but to go with this HOB that had the motor on the outside. And it's actually really good. So my thoughts as to why I really like this one: 1. This filter is small and slim, but has ENOUGH space for me to customize the filter media (see pictures). 2. Super quiet...in fact my air pump is louder than it. The main feature that helps is that there is a rotating piece you can turn to put some space between the tank and the motor. That's the key there. I had rattles when it was up against the aquarium, but now that I turned that disk and created space, you don't hear anything but the trickle of water (when I turn off my air pump). 3. It comes with a suitably sized pre-filter that covers the intake pipe. My shrimp have safely climbed on to eat some of the food on it and combed off. It is coarse, but for a pre-filter I prefer that as it sufficiently catches large debris without greatly diminishing the water suction. I mean, I want most of the filtering to be done in the chamber anyways. 4. Easy to take apart and clean out sludge 5. The suction isn't too strong for my tank community. No one is fighting the current like they initially were when I tried an internal filter system. 6. It's size is easy to manage and work with while still being big enough to do a proper job. Things I learned to be aware of: 1. One other reviewer mentioned that this pump had sucked out water out of the tank and spilled it outside the tank. THIS CAN BE TRUE. It actually happened to me also, BUT I learned that there is an easy fix and it hasn't repeated that problem ever since. Simply put, I initially over stocked the chamber with media so it ended up displacing the water to much that it spilled out of the filter. I stripped it down (see the picture) and it works like a charm. No spillage...not even a little water dripping out of the top. And the biggest culprit was that I had a sponge that was way too dense in there. 2. When using an HOB this small (especially for a planted aquarium that uses soil), it will be necessary to clean the filter once a week. This also helps to prevent overflow. It's the nature of the beast. 3. The noise issue can be real as another reviewer noted...but just as I stated, the rotator disk they have at the bottom of the motor makes the rattles disappear. Again, the key is putting a gap between the tank and the motor component of the HOB. So all in all, I am pleased with this purchase and will be going for this filter again if I ever require one for another nano tank.

I was specifically looking for a very small filter that could fit on the back of my 1-gallon nano tank, and this filter checked all the boxes. It's incredibly compact, making it ideal for tight spaces without being an eyesore. What impressed me most is how quiet the motor is—it's practically silent. I actually had to put my ear right up to it just to make sure it was even running! That’s how discreet it is, which is a huge plus for a bedroom or office setup where noise can be a distraction. Another thoughtful feature is the extra piece included for the downpipe. My tank is fairly shallow, so being able to shorten the downstream length made installation smooth and hassle-free. Overall, I’m very impressed and happy with this purchase. It’s efficient, quiet, and clearly designed with small tanks in mind. Highly recommend for anyone running a nano setup!

Just got it but it primed easily and seems to work well. Love that it has a coarse prefilter and the media seems ok for this size of tank. We will update if we have any problems. Use foam to prop it up since motor can be a bit hummy. But my betta is happy with the flow in the 5.5gallon.

Pictures are of a 1.75 gal cylinder glass vase. Although this filter does work the motor is rather loud. There aren't many options for small filters like this so I purchased two of these to give a try and they are ok. Would I recommend these to others? Mmmm, sure I suppose. I feel like the price point is low enough and may reflect the lower quality. I do like that the flow is adjustable and works as it should, the actual filter just kind of sits in the housing it is not form fitting. Overall I suppose this will work for my application but may be annoying to have in a place where you expect to have peace and tranquility like a bedroom or an office, unless you don't mind a humming sound from the motor. As for longevity that I am not sure, the humming could be from an unbalanced impeller or high resistance not sure.

I was really hoping this filter would work well for my small tank, but it’s been a huge letdown. The water flow is extremely weak, and it doesn’t seem to filter the water effectively at all. I noticed debris and cloudiness building up quickly despite running it continuously. It’s also noisy for its size, and the suction to hang on the tank is flimsy, so it doesn’t stay in place well. Overall, it feels cheaply made and not reliable—definitely not worth the purchase.

I have a couple of low maintenance tanks one with shrimp one with some beta fish I just needed something to filter the water I use my own Media. comes with a little sponge filter to cover the nozzle. You can’t beat this price. I am buying more super quiet, compact versatile it’s on a couple of different tanks that I have. Currently using this on a 6 gallon and a 5 gallon just for reference.

This is a great little filter I have a small 3.5 gallon quarantine tank. I replaced the cartridge with a sponge and a small peice of floss. The tank is in my bedroom and I cant hear it at all. it works really well! There were larger particles not getting sucked into the sponge filter so this gets those out with ease. I highly recommend the smallest one on a tiny nano tanks.

I use this filter for my small shrimp tank and it works fine. The build quality is good and the noise level is acceptable. I cleaned the filter with tap water so I don’t need to replace the filter very often. If you are looking for a low budget filter, you should consider this one.

El filtro me llego en buen estado, es funcional y pequeño, es perfecta para una pecera de 10 litros

No hace nada de ruido y funciona muy bien. Le puse una plantita.

Only negative as others have mentioned is it was a bit loud. Think of a 4 out of 10 in sound. But I put a small piece of foam where it meets the glass. No more noise. Great little filter for the price.

Simplemente dejo de funcionar a la semana de compra
