Fluval and Fluval Sea is a trusted leader in the aquatics industry, and we have a range of Fluval external fish tank filters and internal filters to suit all aquariums. Fluval internal filters are very easy to install and sit directly inside your fish tank, helping you save space and keep your aquarium clean and healthy.

Filtration is essential in any aquarium, no matter the size or water type, so finding the right filter is an important step in setting up your tank. Fluval filters come in a range of sizes and specifications to suit all aquarium types, and are incredibly easy to install and maintain.

Internal filters to suit all compact aquariums

Fluval’s range of internal filters is ideal for those looking for a low-maintenance option, as they can be easily opened for cleaning and filter media replacement. Internal filters work by drawing water from the aquarium using an internal pump, feeding it through the filter media and then returning the clean water to the tank, keeping your aquarium fresh, clean and healthy for your fish.

As well as being essential for health, Internal filters are great space savers for those with limited space around the aquarium, as they can simply sit inside it. However, if you do have more available space, such as a cupboard underneath your tank, it is worth exploring the option of using an external water filter, as this will free up more space for your fish.

In our collection you will find Fluval U2, U3 and Fluval U4 internal filter models, along with Fluval U Mini and Fluval U1 models, which are ideal choices for smaller tanks.
