Hang On Filter

Our Hang-On Back Filter category covers the clip-on power filters that hang off the rear rim of your tank, drawing water up through a media chamber and returning it over a gentle waterfall. We stock the proven AquaClear range alongside the Fluval C Series, the refillable Oase BioStyle in 75, 115 and 180 sizes, and budget-friendly EBANG units like the EB-A01 and EB-02/03/04, plus accessories such as the Qanvee GS hang-on glass thermometer to round out the back of the tank. HOB filters suit the way most of us keep aquariums in Singapore: compact nano and HDB-friendly setups where a full canister is overkill and floor space is tight. They sit outside the tank, so they free up internal volume, run quietly, and are easy to open for a quick media rinse during our humid weather. For shrimp tanks or fry, just add a pre-filter sponge over the intake to keep small livestock safe. If you are choosing between styles, our guide to aquarium filter types explains where HOBs fit, while our best hang-on back filter and nano-tank HOB picks help you match a model to your tank size. To get the biological balance right, pair your choice with the media in our broader filtration equipment range.
