Does the water have to be filled to the top to use?** A: Yes, it includes the additional tube to extend. It will be better to fill filter case completely with water before it starts. Otherwise, it will take some time to pump water up. (Water must at least cover the motor.) **Q: What if the filter doesn't start or makes a mechanical noise?** A: Try to turn the impeller by hand. Check to see if something is jammed in the impeller. Rinse impeller and filter to remove blockage. Then verify free rotation and priming. Then verify the impeller is free to rotate, and the filter primes correctly. **Q: After a powerout, will this filter restart on its own?** A: Yes, the motor will restart by itself once the power turns on. **Q: Can I use this in a turtle tank?** A: It is not recommended for turtle tanks. **Q: Does this filter fit on a framed aquarium?** A: Yes, you need to gently pull the intake tube to hang on your framed aquarium. The width between intake tube and housing is 0.4 in. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good little HOB filter *by on Reviewed in Canada 12 August 2026* This is a nice little HOB (hang-on-back) filter that I’m currently using on a 6-gallon planted tank. It has a compact design, has adjustable flow, and, best of all, it’s very quiet. I barely notice it running. So far, I’m very happy with its performance and would definitely recommend it ### ⭐ Bad quality and potentially dangerous to your fish. *by on Reviewed in the United Arab Emirates 10 July 2026* Stopped working within 24hrs. Noticed my thermostat temperature creeping up, was set at 27 and ended up at 30 which means this pump over heated and affected the tank water temperature also! And I bought 2 for 2 tanks both exactly same and stopped working. ### ⭐⭐⭐⭐⭐ Literally obsessed with this filter *by on Reviewed in the United States 3 October 2026* Firstly let me say this filter looks GOOD. I originally bought a very similar-looking filter from a smaller store but I definitely did not like how loud it was, the fact that they forgot to include the lid, or how damaged the box was. This filter is better in some ways, less sturdy in others. For example, the way the pipes fit together feels a bit cheaper.The filter runs better than the last one did, too, with a stronger flow, less sound, and better media. I really like this filter! It's genuinely probably the best filter I have had on any tank and it's odd that it was just a "cheap" nano filter lol. I've had a 26 gallon tank and a 20 gallon tank and two 5 gallons before, I've probably been through at least 8 filters, maybe 9?? This is the most well-suited filter for any of the tanks I've had in the past! For tiny tanks up to 8 gallons apparently. This one works very well for my small, planted 3.5 gallon shrimp tank! There are more things I could rant and rave about this filter but I'll end it here lolOh, but also like that it was next-day shipping, like what??? I love having an Amazon warehouse ten minutes from my house ohmigosh 😭 ## Frequently Bought Together - NICREW Slim Aquarium Filter, Quiet Fish Tank HOB Filters for up to 5 Gallon Aquariums, Adjustable Flow, 42 GPH, 3W - NICREW Slim Aquarium Filter Cartridges (6 pcs) with Intake Sponges (2 pcs) - DaToo Mini Aquarium Heater 25W Small Fish Tank Heater 25 Watt with Free Thermometer Sticker --- ## 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.co.za/products/729816242-nicrew-slim-aquarium-filter-quiet-fish-tank-hob-filters-up](https://www.desertcart.co.za/products/729816242-nicrew-slim-aquarium-filter-quiet-fish-tank-hob-filters-up) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-11-10*
