Why Choose a Canister Filter for Your Tank?

The benefits of canister filters include:

High-flow Rates

High-flow rates keep the water clean and free of contaminants at all times. The best canister filters will have rates of above 200 GPH. They will be perfect for tanks that require a lot of filtration flow.

If you are keeping species that produce a lot of waste or are very sensitive to water quality, you will be better off using canister filters.

Most canister filters are equipped with spray bars that you can direct to the water’s surface to get rid of scum.

Flexibility in Choice of Filter Media

Canister filters will allow you to customize the kind of filter media you use for your aquatic setup.

Different aquariums will demand different filtration systems. There is plenty of media for purchase, depending on the kind of pets you have kept. You can also re-order the media if you get new animals or get a bigger tank.

Clear Views of the Aquarium

Most people like to situate their aquariums in rooms like family areas and high-traffic setups like restaurants. A canister filter is suitable because the major part of the system will be concealed in the cabinet.

A model with an inbuilt heater will also erase the need for keeping a heater in the aquarium. Canister filters also provide sufficient aeration, thus eliminating the need for an air pump.

Quiet Operation

Canister filters have none of the vibrating noise associated with hang on back filters. You often have to check your canister filter to ensure it is still working. Canister filters are still powerful, even with the silence.

Suitable for Large Tanks

While sponge and hang on back filters will fit small-sized aquariums, you need a canister filter for a large setup.

Durability

Most canister filters will boast of German or Italian engineering. Companies opt for sturdy and reliable manufacturing with their canister filters, to ensure their models are long-lasting.

Conclusion

Aquarists favor canister filters for their efficient operation. They can be notoriously pricey, although brands like EHEIM, Penn Plax, Marineland, Aqueon, and OASE have affordable designs that will suit your budget.
