So, it looks like you have developed the hobby of keeping aquatic plants and animals. You should know that you will need plenty of equipment including tank and filter to keep your aquatic plants and animals alive and well. After choosing the size of the tank, you will also need to choose the filter accordingly.

We can´t stress on how important it is to keep the water in your aquarium clean and in an impeccable condition. The aquarium filter helps in maintaining the cleanliness of the aquarium, sanitizing the tank by killing bacteria and germs, oxidizing the tank by controlling organic debris and deterring algae, thus, ensuring the well-being of your aquatic plants and animals. However, the filters must also be cleaned every once a while to make sure that it is fully operational. It is imperative that the filters perform at an optimum level. Hence, you can´t make any reservations while purchasing aquarium filters. We would advise you to purchase an under gravel filter since it´s moderately priced while offering plenty of benefits. However, there are other types of filter available for purchase and we would advise you to think for a while before making a purchase. There are primarily six types of aquarium filters with each having its own advantages and disadvantages.

1. Corner (Box) Filters

Corner filters are relatively inexpensive and work best with small tanks (10 gallons or less). As its name suggests, this filter sits in one corner of the tank and works like a charm on hospital and fry tanks because of its gentle operation. However, this filter is not for you if you are looking for something that is aesthetically pleasing.

2. UGF (Under Gravel Filter)

Under Gravel Filters have filter ¨plate¨ placed under the substrate or gravel of your aquarium. Although they make an exemplary biological filter, they don´t work quite as well as a mechanical filter as they tend to clog over time, and they don´t include chemical filtration.

3. Sponge Filters

Simple to use and inexpensive, sponge filters are generally used in small hospital and breeding tanks. Sponge filters feature an airlift tube that forces water to pass a porous sponge that collects debris and bacteria. They work well as mechanical and biological filters.

4. Power Filters

Power Filters are commonly used by the masses today as they provide outstanding mechanical, chemical, and biological filtration. Power filters boast of an intake tube through which water

passes; then, the water goes through a chemical filter cartridge and then through a biological sponge before flowing back to a tank. Many hobbyists swear by the benefits of power filters.

5. Wet/ Dry (Trickle) Filters

Wet/ Dry (Trickle) Filters are popularly used by saltwater and freshwater enthusiasts. Comprising primarily of two sections, the ¨wet-dry¨ compartment and the ¨sump¨compartment, this filter is on the expensive side of filtration options. How does the filter work? Well, the water first trickles over a plastic plate into the wet/dry area. Then, it flows through a baffle which usually boasts of an activated carbon unit, before making its way into the sump, where the water is delivered back into the aquarium.

6. Canister Filters

Canister Filters work best when installed in large tanks as these filters have the capacity of filtering large amounts of water pronto! Canister filters are placed underneath the aquarium, completely out of sight.
