Setting up your first aquarium can be an exciting experience, but you need to make sure you have the necessary equipment to keep your aquatic pets healthy and happy. A filter is one of the most important pieces of equipment you will need as it keeps the water clean and healthy for your fish. With so many different types of filters on the market, it can be difficult to know where to start. We’ve researched some of the most popular types of aquarium filters, including their features, pros and cons, to help you make an informed decision and set up the ideal filtration system for your aquarium.
Hang-On-Back (HOB) Filters:
HOB filters, sometimes called power filters, are aquarium filters that hang on the back of the aquarium. To generate the water flow and pump it through the filter media, they use a motor-driven impeller. HOB filters are popular with aquarium enthusiasts because they are easy to install and maintain while providing effective and reliable filtration.
HOB filters remove litter, waste particles and harmful substances from water through mechanical, biological and chemical filtration. They work by drawing water through a range of filter media, such as sponges, charcoal and biological media, which trap and remove pollutants from the water.
One of the main advantages of HOB filters is that they are suitable for all sizes of tanks. They can be used as primary or secondary filters in combination with other types of filters in both freshwater and saltwater aquariums.
Overall, the HOB filter is an excellent choice for anyone looking for a quality, efficient, and easy-to-use aquarium filter. They are especially useful for small aquariums and hobbyists looking for an easy-to-install and maintain filter.

Pros:
- HOB filters are affordable and widely available.
- They are easy to install and maintain.
- They provide efficient mechanical and biological filtration.
- They are suitable for most small to medium aquariums.
- They can be customized with different filter media to suit your needs.
Cons:
- HOB filters can be noisy, especially if the water level in your aquarium is too low.
- They may not be suitable for larger aquariums or heavily stocked tanks.

- They take up space behind your aquarium and can be unsightly.
- They may not provide adequate chemical filtration for some fish or aquarium settings.
Canister Filters:
A canister filter is a form of canister filter that stores filter media in an airtight canister. They are strong and able to handle large volumes of water, making them ideal for larger aquariums. To remove dirt, waste particles, and harmful compounds from water, tank filters typically use a combination of mechanical, biological, and chemical filtration.
Canister filters have a huge filter media capacity, allowing them to handle large volumes of water and still provide excellent filtration performance. They are also notoriously quiet since the engine is out of the tank.
Canister filters are suitable for both freshwater and saltwater aquariums and are especially effective in tanks that require a high level of filtration, such as aquariums with abundant B. fish or those with large fish. They can also be combined with other types of filters for even more efficient filtration.
A potential disadvantage of canister filters is that they are more difficult to install and maintain than other types of filters. However, many aquarists feel that the benefits of a canister filter outweigh the additional hassle of installation and maintenance.
Overall, canister filters are a great choice for anyone looking for a powerful and effective filter for their aquarium, especially for larger tanks or those with high filtration requirements.

Pros:
- Canister filters provide high-performance mechanical, biological, and chemical filtration.
- They are suitable for larger aquariums or heavily stocked tanks.
- They can be customized with different types of filter media according to specific needs.
- External filters are usually very quiet in operation.
- They are very effective at removing debris and debris from aquarium water.

- They may not be suitable for small to medium aquariums.
Sponge Filters:
Sponge filters are often used in small aquariums or as secondary filters in larger tanks because they are inexpensive, easy to maintain and provide adequate biological filtration. They’re also popular with growers and hobbyists who need a constant flow of water and don’t want to disturb the tank’s substrate or plants. Overall, sponge filters are a simple and effective technique for keeping the water in your aquarium clean and safe for aquatic life.
The sponge filter is an aquarium filter with sponge as the main filter material. Sponges are usually made of foam and are designed to capture and remove particles of dirt and debris in the water. Sponge filters work by drawing water through the sponge, which acts as a mechanical filter, collecting larger particles and providing a surface for the growth of beneficial bacteria. These bacteria then help break down and remove toxic chemicals and toxins from the water, making it safe for fish and other aquatic life to swim.

- They may not provide adequate chemical filtration for some fish or aquarium settings.
- They may not be aesthetically pleasing to some aquarists.
- Sponge filters are bulky and take up space in the aquarium.
Internal Filters:
An internal filter is an aquarium filter designed to be submerged in the aquarium’s water. These filters often use a combination of mechanical, biological and chemical filtration to remove dirt, debris and harmful chemicals from water, keeping aquatic life safe and healthy.
Internal filters can come in all shapes and sizes, from small, compact units for small aquariums to larger, more powerful filters for the needs of larger aquariums. They are often favored by aquarium enthusiasts who want a filter that is easy to install and maintain, and that doesn’t take up too much space in their aquarium.
Internal filters are also known for their versatility and can be used in a variety of applications including as primary filters, secondary filters or as emergency backup filters. Overall, internal filters are a reliable and effective way of keeping aquarium water clean and healthy and ensuring a safe and comfortable environment for aquatic animals.
