External & Internal Fish Tank Filters at AllPetSolutions

Keep your fish tank water clean and your finned friends happy with our fantastic range of aquarium filters. Whether you need internal filters or external filters, we have them all. Internal filters suit smaller tanks and are quick to service, while external canister filters hold far more media and keep the hardware out of sight, which counts for more as the tank grows. Sitting between them are hang-on-back units and simple air-driven sponge filters, the latter a common choice for fry, shrimp and quarantine tanks.

Replacement aquarium filter foams and media are stocked separately, and an aquarium heater or air pump completes a healthy tank.

Buying guide

Start with turnover: around four times the tank volume every hour keeps a community tropical tank clear, with a little more for messier species such as goldfish or larger cichlids. Quoted flow rates are measured with an empty filter and no pipework attached, so sizing up gives you useful headroom once media and hoses are in place. Rinsing media in old tank water keeps the beneficial bacteria thriving. Internal, external and hang-on filters are all here, rated by tank volume.

Which are the Best Aquarium Filters?

Aquariums filters perform an essential job, by removing any dirt or chemicals from your fish tank and keeping the water clean and high quality.

AllPetSolutions know that some fish owners prefer the external control gained by using an aquarium external filters. You may find you don't have space, or you are looking for something a little more streamlined based within your aquarium and choose an internal filter. For those who want an easy setup, you can choose from our aquariums with a filter built in.

When it comes to selecting the right filters for aquariums, there are lots of factors to consider:

The capacity of your tank.

Whether you have freshwater or saltwater fish.

Easy access to clean your external aquarium filter.

The power usage of the filter aquarium.

We offer every variety of internal and external filters for aquariums of all sizes, from Hang On Filters providing a continuous waterfall feature, to low-maintenance Internal Filters, which are simple to use and maintain.

How often should I change the Aquarium Filter Foam or Media?

For most types of filters, you will typically need to replace active carbon every 2-3 month most foams and other media only need replacing when these break down. It is essential to clean your aquarium's filter regularly, including the housing.

Our ranges include convenient multi-purpose filters for aquariums, making maintenance as simple as possible.

Take a look at the Internal Filter with 9W UV Steriliser for the freshest tank yet, or our Clear Adjustable Flow Filter, suitable for tanks up to 600-litre capacity.

Can I get a quiet and discreet Aquarium Filter?

AllPetSolutions external aquarium filter and internal filter ranges include convenient options that slot seamlessly into or beside any size or shape of tank.
