Review: I’ve been using this small internal filter for a few weeks in my 5 gallons tank and it does a good job. It’s compact and easy to set up, and doesn’t 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 you’ll need to clean the sponge fairly often since it’s small, but that’s expected with a filter this size. Overall, it’s a reliable little filter for small tanks. Great value for money.
Review: 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 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. 😢😢
