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 it’s even running, which is fantastic since it’s in my main living room. However, if the bubblers cap is removed It will make noises so I wouldn’t 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 filter’s 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, I’m still pleased with my overall experience and will be keeping it in my setup for now.

Love this!!!
Works great for my 5.5 Gallon tank, I actually modified it some in which then it works even better, inside the filter is a plastic basket that holds a small pouch of carbon, the basket has small holes, so I actually used the Fluval Zeo-Carb loose in there, it is big enough that nothing escapes! Works great! Then I trashed the little pre filter that comes with this, I felt it had large pores which let a lot through, and I got the Fluval Phosphate filters, and I cut them to size and put them as the pre filter, I think it makes it one of the most efficient filters I’ve ever had, and it SUPER QUITE I love that if I keep it just slightly above the water as it sprays from the long attachment it creates some bubbles, enough that my guppies are super happy, which is good because typically bubblers are very loud.

Good little filter
A little strong for a 10 gallon, but surprisingly good. I would use it more for a 20 gallon unless you need a lot of water movement in your smaller tank. Keeps the water clear and the sponge will hold beneficial bacteria. It’s quiet and the suction cups are good and hold it in place very well.

Frustrating
Update: I gave up on this. It gets clogged up so easily, I was having to clean it every day or it would stop working right. I’ve got 8 tanks, I’m not inexperienced but I struggled to make this filter work correctly. I went back to a sponge filter and my tank is so clear now! I should have kept it running instead of this filter.________I’ve never had so much trouble with a filter before. I was using an internal sponge filter and switched to this filter because the tank is in my bedroom and the bubbling was annoying.The pieces aren’t great. I wanted an elbow piece to attach to the spray bar so the spray bar was vertical with the filter but the pieces don’t fit together to make this. *Edit: if you use enough elbow pieces you can do this but the spray bar is very longI keep having to clean this filter out, things keep getting stuck to the slits on the side where it pulls in water. You would think that’s a good thing but it blocks the filter and then the air tube and regulator stops working and doesn’t produce bubbles anymore.If you have the air tube and regulator on it helps to turn the tubing inlet so it is horizontal, it seems to keep the water from going into the tubing, th water stops air from coming out when this happens. It’s also very loud. I don’t know if it’s the regulator that is bad or what but the bubbles are really fine and they crackle as they come out. You can close the regulator almost all the way and it is still loud, sometimes it sends the air out in short loud bursts.Ramshorn snails keep getting stuck in the part of the filter where different arts connect, they are getting their bodies stuck in crevices then they can’t get back out and they die. I learned this the hard way when I went to pull one off the filter and I pulled it’s insides out of its shell.As of right now I definitely wouldn’t recommend this filter

Powerful aquarium filter at a budget price!
GREAT little filter! I have the 5-10 gallon unit in a 2.5 gallon tank. Because its acrylic (not glass) and there is no real stand for my setup, it seemed quite loud. I put some rubber pads under my aquarium and it deadened the noise significantly. That was strictly a problem with MY SETUP, not the pump!Water is clean and the fish are probably enjoying the jet of water in their tank, probably makes it feel like they’re in an actual stream!

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.

I bought this product, but when I used it for the first time, it didn’t work. What a waste of money. I wish the seller would give me a replacement. 😢😢
