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: We love it - We've had this plugged in for 4 hours and it's waaay better than the original filter that came with our aquarium. We have a 2.5 imagitarium tank from Petco. The original filter didn't really move much water. This one is probably overkill for this size tank but it's awesome and we see a major improvement in overall filtration. We are using the waterfall attachment and we love how it spreads out the bubbles through the entire tank. We can actually see bubbles circulating every sq inch of our tank; again, might be overkill for our size tank, but our tank has never been cleaner. The pump itself is silent, and the waterfall is about 1/8" above the water and it makes just enough noise to be soothing to the ear. It fit perfectly in our small tank. I hope this lasts a long time, but even if it lasts 6 months (which is how long our Petco pump lasted, we'll be pretty satisfied and would purchase again. ## Features - Provides effective and thorough biological and chemical filtration, creating superior aquarium water environment - Activated carbon and fine filter foam trap debris and fish waste, absorb odors - Enable to generate abundant air bubbles and water flow, optimal for oxygen supplement and water circulation of aquarium - Equipped with adjustable air regulator that distributes a gentle flow of water, making it safe for delicate fish or shrimp - Quickly assembles and disassembles, comes with four suction cups for secure in-tank installation, suitable for both freshwater and saltwater tanks ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.2 out of 5 stars 1,755 Reviews | ## Images ![NICREW Internal Aquarium Filter for Fish Tank up to 5 Gallons, 40 GPH - Image 1](https://m.media-amazon.com/images/I/71Wq56pRoFL.jpg) ![NICREW Internal Aquarium Filter for Fish Tank up to 5 Gallons, 40 GPH - Image 2](https://m.media-amazon.com/images/I/71T--Qwu9XL.jpg) ![NICREW Internal Aquarium Filter for Fish Tank up to 5 Gallons, 40 GPH - Image 3](https://m.media-amazon.com/images/I/81VJFJjNZML.jpg) ![NICREW Internal Aquarium Filter for Fish Tank up to 5 Gallons, 40 GPH - Image 4](https://m.media-amazon.com/images/I/71S1UuVgYTL.jpg) ![NICREW Internal Aquarium Filter for Fish Tank up to 5 Gallons, 40 GPH - Image 5](https://m.media-amazon.com/images/I/71SDw26i0zL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is it noisy when in use?** A: The filter can be used completely submerged in water for quiet use. **Q: Can the filter be cleaned?

I was pretty surprised at the amount of flow they have, even placed or the short side of the tank everything has good movement. For as cheap as they are they seem to be well made, and even included an extra impeller, as well as several options for setting up the outlet, I opted for the flow bar. This little unit cleared silt from a new tank quickly, in about 24 hours, and is still running strong and the water is really clear. There is no noise that I can hear, but YMMV because I don't have the best hearing, though definitely quieter than my most silent air pumps. Super easy to install, I haven't tried cleaning the filters yet but the bottom case below the pump comes off and it looks fairly easy. The filters are small, but this whole unit isn't much larger than a small sponge filter, volume wise probably about the same, but with actual flow. I would definitely buy these again if I needed them, and I bought a backup set of filter media for future use since these don't have a permanent home right now. The spray bar can be positioned in any direction, I have it pointed slightly towards the surface to break up any biofilm, if I had floaters I'd have to change that but I'm not growing any in this plant nursery tanks. ## Frequently Bought Together - NICREW Aquarium Internal Filter, Submersible Power Filter for Fish Tanks 40-66 Gallon, 264 GPH - NICREW Replacement Cartridge Fish Tank Filter Magi 700, Aquarium Filter Foam and Active Carbon --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/577003015-nicrew-internal-aquarium-filter-for-fish-tank-up-to-5](https://www.desertcart.sg/products/577003015-nicrew-internal-aquarium-filter-for-fish-tank-up-to-5) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-10*
