Why is an external filter the most effective solution for your aquarium?

An external aquarium filter provides significantly better filtration compared to internal models. This is due to its larger volume and the possibility of using a variety of filter media that perform mechanical, biological and chemical purification. It is located outside the aquarium, which saves valuable space inside and does not spoil the underwater landscape.
To maintain a spotlessly clean and healthy environment for your aquarium inhabitants, it is important to understand the benefits of external filtration. Here are the main reasons why canister filters are so highly valued.

• Superior filtration capacity: The large volume of the canister allows for the arrangement of several layers of different filter media. This provides a much more thorough and complete purification of the water from all types of contaminants.
  
• Flexibility in choosing media: You can freely combine different types of sponges, ceramics, activated carbon and other specialized materials. This way you customize the filtration according to the specific needs of your aquarium.
  
• Constant and strong flow rate: External filters maintain a more powerful and constant water flow. This ensures excellent circulation and aeration, which are vital for fish and plants.
  
• Hidden location and quiet operation: Since the filter is outside the aquarium (for example, in the cabinet below it), it does not disrupt the aesthetics of your underwater garden. Modern models are designed to operate extremely quietly.
  
• Less frequent maintenance: Thanks to its large capacity, an external filter does not need to be cleaned as often as internal alternatives, saving you time and effort.
  

All these advantages make investing in a quality external aquarium filter an extremely wise decision for any serious aquarist.

How to choose the right external filter for your aquarium?

Choosing the right external aquarium filter depends mainly on two factors: the volume of your aquarium and the number of its inhabitants. The correctly selected model will provide optimal filtration without creating too strong a current that can stress the fish. It is always better to choose a filter with a slightly larger capacity than the recommended minimum.
Before making a final decision, pay attention to a few key technical characteristics. They will help you find the filter that perfectly meets your requirements and budget.

• Flow rate (liters per hour - L/h): This is the most important parameter. The general rule is that the filter should be able to cycle the entire volume of your aquarium between 3 and 5 times in one hour. For example, a 100-liter aquarium requires a filter with a flow rate of at least 300-500 L/h.
  
• Filter container volume (canister): A larger volume means more space for filter media and, accordingly, more efficient and long-lasting purification.
  
• Energy consumption: Although they work constantly, modern external filters are energy-efficient. Compare the power (W) of different models to optimize your electricity costs.
  
• Package contents: Check if the filter comes with hoses, pipes and filter media included. Some models come fully equipped and ready to work, while in others the media must be purchased separately.
  

Careful consideration of these details will ensure that you make the best choice, and a good external aquarium filter price will make your purchase even more satisfying.

Frequently asked questions

1. What is the main difference between an external and internal filter?

The main difference is in the location and capacity. The external filter (canister) sits outside the aquarium, has a much larger volume for filter media and provides better filtration. The internal filter is submerged in the water, takes up space and is mainly suitable for smaller aquariums with few fish.

2. How often should I clean my external aquarium filter?

Unlike internal filters, external filters need cleaning much less often - usually once every 1 to 3 months, depending on the load of the aquarium. It is important to use aquarium water and not tap water when cleaning the biological media (ceramics, lava) to preserve the beneficial bacteria.3. What filter flow rate is needed for my aquarium?

3. What filter flow rate is needed for my aquarium?

The recommended flow rate is the one that allows the filter to process the entire volume of your aquarium at least 3-5 times within one hour. If you have a heavily populated aquarium or keep larger fish that pollute more, aim for a flow rate that is 5-7 times the volume of the aquarium.

4. What is the average external aquarium filter price and what does it depend on?

The price of external filters varies depending on the brand, flow rate, canister volume and the accessories and media included in the kit. Models for smaller aquariums (up to 100 l) are more budget-friendly, while those for large aquariums (over 300 l) represent a more serious investment, which, however, guarantees the impeccable health of your ecosystem.
