The best aquarium filter types for your fish tank guide

Power, canister, internal, undergravel filters are the best filters for fish tank today. All of these types of aquarium filters can be used for either freshwater or saltwater fish tanks.

Power Filters

Power filter is the most common choice in most cases, particularly for tanks under 55 gallons. It is very easy to set up, easy to maintain and most importantly not expensive. Power filters with Bio Wheels are another type of power filter which is very common on the market. It offers a complete 3 stage filtration system in one sturdy, easily installed and maintained filter. It is the best choice for freshwater and marine tanks up to 75 gallons.


Canister Filters

Canister Filters are used in freshwater or saltwater aquariums and are recommended for larger tanks i.e. 30-50 gallon fish tanks and upwards. Canister filters are the best choice for any large fish tank, if you can afford it. As all the filtering is done outside the tank, it keeps the filtered water separate from the unfiltered water until it is returned to the tank. A couple of long hoses connect the filter to the tank; one supplies the filter and the other returns the filtered water to the tank. This type of filter is the most effective but also the most expensive.


Internal Filters

Internal Filters are fully submersible filters that work inside one aquarium. It is useful for small fish tanks for Betta or other small fish as it does not tend to have large media chambers. In the case of larger tanks they are useful as supplements to an external canister filter. It is also a great choice for the low water habitats like turtle tanks.

One can purchase any these types of filters at the local fish shop, but one may face harder time to find out the more expensive external type at a general pet store. The external fish tank will cost more up front but in the long run one will save on maintenance costs and fish costs as one will be providing the best habitat that they will live long and healthy lives.


UGF or UnderGravel Filter

UGF or Under Gravel Filters have been used for several years by people with great results. Unfortunately, this kind of filter gets bad press by people who do not know the basic idea and the necessity of maintaining these filters.

UGF filters usually consist of hard plates that sit at the surface of the fish tank. These plates are raised a bit from the surface in order to support the layer of gravel. You can find minute slots in the riser tubes and the hard plates.

A water pump or air pump known as power head is being used to move the water up to the riser tubes. This water then flows through the gravel bed, up the riser tubes and under the hard filter plates. This water brings in oxygen and promotes development of bacteria. All these bacteria’s metabolize nitrate and ammonia in the fish tank.

This results in a very efficient biological filter. Regrettably, the wastage is pulled off into the gravel layer and because of this the gravel layer gets clogged and results in poor quality of water. This is why it is important for you to change the water and clean the gravel regularly. This can be easily done with the help of gravel vac or a siphon hose that allows you to take-out the waste from the gravel surface while changing the water. The UGF filter is cheap and reliable provided you are keeping the gravel surface free of debris.


Wet-Dry or Trickle Filters

These filters are usually placed underneath the stand of the fish tank. Water is then gravity fed to these filters where bacteria beds are supported. These bacteria’s consist of biowheel, biological and other bioballs media. The main point is that all these media’s must be removed out of the fish tank. In this case, water is enabled to trickle over the media and at the same time be exposed to the air. This results in extremely huge particles of bacteria developing which are capable of supporting extremely large sized fish loads. All the trickle filters usually have a pre-filter that serves for the mechanical filtration. In case you have decided to design your own filter then it is necessary that all the bio-media is left out of the water. Covered media normally defeats the intention of having trickle filters and besides that you can even try to use sponge filters.
