- Adjustable flow control knob
- Excellent for small aquariums under 10 gallons
- Great betta tank filter
This nano hang-on-back filter is excellent for aquariums under 10 gallons. It moves 52 gallons per hour and has an adjustable flow knob for fish who need lower flow such as bettas. It comes fully equipped with media and an intake sponge. However, upgrading to our mini pre filter sponge is ideal as it offers greater coverage of the intake tube with less clogging from debris. Hot rod this filter by adding coarse sponge to the media portion rather than the provided cartridges.
Customer Reviews
The Aquarium Co-Op HOB Filter works very well. It is easy to put together and runs quietly. You can turn the flow up or down so as not to push your fish around . I love my new filter
Not only is this the perfect filter for a five gallon tank but it also propagates plants like a champ! If Aquaclear/Fluval made a version 10 filter, this would be it. The adjustable flow is perfect for Lucky Luciano to live out the rest of his days. 💚
This nano hang on back filter is a work horse. This is the 3rd one I've purchased. Every 3 weeks to a month I take them apart and clean them ..... very easy to do ..... they just keeps on working. Make sure you clean it and it won't let you down. Thank you Aquarium Coop for having this item in stock.
Great shipping and great filter for betta fish I highly recommend
This little filter is perfect for my UNS 45S tank. It’s been working hard and removing tannins etc from my new setup.
