Great little filter for small tanks
Iâve been using this small internal filter for a few weeks in my 5 gallons tank and it does a good job. Itâs compact and easy to set up, and doesnât take up too much space inside my aquarium.The flow is gentle enough for my fishes but still keeps the water moving and super clear. It runs pretty quietly too, which is a big plus, but it is not completely silent either.The only thing to note is that youâll need to clean the sponge fairly often since itâs small, but thatâs expected with a filter this size. Overall, itâs a reliable little filter for small tanks. Great value for money.

Good for a small aquarium
Great little water filter. I purchased this for a small 5 gallon setup for crabs. I needed something that would fit into the smaller space, I could fully submerge with only half the tank full, and something that didn’t have overpowering suction. This little filter fit the bill. You can install it horizontally or vertically which makes it very versatile. The filter inside is reusable and you can change the position of the water way out. This work great for crabs.

Filter too strong and kinda loud but works well.
It works very well but the filter is too strong for the size tank it says itâs for. I wish I bought the smaller version then. My 10 gallon has lots of current. Itâs pretty loud. My water is very clear though. No smell. Easy to assemble.

Satisfied purchase.
So far this is working great in my giant pixie frogs enclosure. It keeps the water clear and circulated for a couple weeks. Before it needs taken apart and cleaned. The intake tends to get clogged. But that’s to be expected. He has big poops. Lol. And its relatively quiet, which is a definite plus!

Small, Quiet, Yet Surprisingly powerful
I recently purchased the filter for my 10-gallon aquarium, and after a few weeks of use, I feel compelled to share my thoughts on this compact device. As someone who values both functionality and tranquility in my fishkeeping experience, I’ve found this filter to be a mixed bag of brilliance and overpowering performance.**Pros:**1. **Compact Design**: The size of this filter is truly noteworthy. It fits seamlessly behind my aquarium decor, allowing for unobstructed views of my aquatic inhabitants.2. **Whisper-Quiet Operation**: One of the standout features of this filter is its near-silent operation. I often forget itâs even running, which is fantastic since itâs in my main living room. However, if the bubblers cap is removed It will make noises so I wouldnât recommend doing that.3. **Easy Installation and Maintenance**: Setting up the filter was a breeze. The instructions were clear, and it took no time to have it up and running. Cleaning and changing the filter is straightforward, which is essential for someone with a busy schedule.**Cons:**1. **Too Powerful for Small Tanks**: While the filterâs strength may be beneficial for larger aquariums, I found it to be a bit too powerful for anything under a 10-gallon setup. The water flow is strong enough that it creates a significant current, which can be distressing for smaller fish and plants. I’ve had to adjust the outflow angle to try to minimize the turbulence, but it still feels excessive in some parts of the tank.2. **Limited Flow Control**: I wish there were a more effective way to regulate the flow rate. The filter operates at one speed, which can be overwhelming in a small tank that needs gentler filtration.Overall, the filter is a fantastic choice for those who need a small and quiet filtration solution, but potential buyers should be mindful of its potency. If you’re using it in a larger aquarium or are keeping more robust species that can handle higher flow, this filter might be a perfect fit. For those with delicate fish or plants, I recommend considering whether the strong current can be adequately mitigated before making this purchase. Despite its power, Iâm still pleased with my overall experience and will be keeping it in my setup for now.

Quiet awesome pump
This pump is awesome in my 5 gallon Fluval reef tank. It gave just enough extra flow badly needed and filtration as a bonus. It is absolutely silent and running flawlessly for several months. Easy to clean and cheap filtration replacements. Worth every penny.

Filters Fine
The filter itself works fine. The oxygenation feature does not supply a steady stream of bubbles but rather spits and sputters and makes a fair amount of noise.

Mighty little pump.
I bought this for my 2 and 1/2 gal betta tank, it has 2 options a waterfall tube or a direct under water nozzle. I wanted to use the waterfall option but the water flow control doesn’t fit on this option. It flows at full power only and it way to strong for my betta, it knocks him all around it when he swims under it. I had to change to the under water nozzle so I could use the flow control. Not what I was hoping for but all in all it is a good little filter and takes up very little space in the tank. It makes very little noise when you turn down the water flow and it is very easy to remove and clean.

I bought this filter in June 2025, and this filter works fantastic so far for my 5 gallon betta tank (I got the mini filter 3.5w)! The tank stays very clean and oxygenized without stressing my betta out, since the waterfall-like option gives a gentle, not overly disruptive water flow that I can adjust the position as needed.My old filter that came with the tank I found was too stressful and my late betta had a hard time swimming through, but my current betta seems to swim around this one with ease. I do have the water flow streaming onto a rock which helps too (see pic).It’s very easy to set up as you just put it together and plug it in, no additional pumps required.Overall, this filter is way cheaper than my local pet stores and works much better without being overpowering for my betta. If it were to break, I would definitely buy this again.

I bought every adaptor I could find and still cannot plug it in properly. Very annoyed that it even needs an adapter in the first place. Basically unusable.

Small but powerful and creates a nice flow in my aquarium. I use it submerged rather than spraying water like a sprinkler. Came with an extra filter that takes replaceable media. Easy to clean too.
