Functions of Aquarium Filter System 

Before you can learn more about which aquarium  filter to buy, it is always better to start from the basics, so we will first discuss the different functions of a fish tank filter.

The functions are categorized into three major classifications to help you choose the right one.

Biological Function

Fish produce ammonia from their gills as they breathe, and also as part of the waste released from their bodies. The ammonia needs to be removed from the tank frequently, as it is quite toxic to the fish.

The use of a filtration system will help in the elimination of the fishes’ bodily wastes from the tank. Sometimes you might find the fish dying from the ammonia accumulation, but this is something that can be easily avoided.

Chemical Function

The water that we rely on for drinking and cooking comes from different sources. Some sources might contain hard metals or other materials which might be harmful to the fish. This creates the need for a filter that can remove such materials from the water.

Different types of filters will have different methods for cleaning up the impurities. Once they are removed, the fish will be surrounded by clean water in which they will be able to thrive.

Mechanical Function

It is common to have debris in a fish tank, due to excess food fed to the fish and other dust particles from the room. The mechanical process of a fish tank filter is meant to remove this debris and any other visible waste from the tank.

Once the water is purified, the tank will contain the clean, clear water both you and your fish prefer. Having a clean and well-aerated tank will promote good health for your fish.

Types of Aquarium Filters

Here are the different types of Aquarium filters you can expect to find on the market.

Air-driven internal aquarium filter

These filters are small, making them great for compact aquariums kept in a hospital or home. Their size makes them suitable for easy integration with a wide variety of fish tanks.

Even though they are small, they can still be very sturdy and well constructed. It will help to keep your small aquarium inhabitants healthy and free from any harm in the water.

Canister filters

The canister filters offer all the functions you need in a fish tank filter. You can expect them to deliver on all fronts—mechanical, chemical, and biological functions.

The body, which is often called the canister, is significantly larger for these filters than it is for other types of filters. Each canister will have locations to hold each different type of filter media, and the large canisters will have more filter media. This type of filter does take more effort to set up and maintain, in exchange for its power and flexibility.

Undergravel filters

These filters are placed in the bottom of the fish tank underneath a layer of aquarium gravel. They move the water through the gravel to create conditions for biological filtration to occur, where beneficial bacteria break down the wastes in the fish tank.

Although the filters are designed primarily for biological filtration, some models also have replaceable cartridges. These cartridges have activated carbon to help with chemical filtration.

Power filters are a type that is widely used in many aquariums. They are relatively easy to set up and last for a long time. Many people love them, as they provide the best performance for biological, mechanical, and chemical filtration.

They are designed to easily hang on back of the aquarium for convenience, and can be used for many different types of fish tanks. The replaceable filter cartridges make maintenance very easy, as compared to other types.

Wet/Dry filters

These are known to be the best in biological filtration. They are designed to be a great fit for saltwater aquariums that demand effective biological filtration.
