Find the right replacement

Match the brand, exact model, model number and part code to your existing equipment before ordering. Similar-looking sponges, impellers and shafts may have different dimensions or fittings. Check whether an impeller includes its shaft and bushings, as several listings supply these separately, and confirm the number of pieces in each pack.

Choose filter media according to its mechanical, biological or chemical function and check the individual product's freshwater or marine suitability. Follow the manufacturer's instructions for media placement, cleaning and replacement rather than using one schedule for every filter.

This collection also contains related aquarium accessories, including a Dalua complete internal filter, Aqua One MiniReef return piping, a Red Sea ReefMat connector kit, OASE Hel-X pond biomedia and a Bioscape CO2 diffuser. These serve different purposes and are not universal internal-filter replacements. Check each listing's intended application and delivery requirements.
