Why You Need an External Aquarium Filter for Your Fish Tank

As an aquarium owner, you probably know that keeping your fish healthy is crucial. One of the most important ways to ensure that they stay healthy is by using an external aquarium filter.

So, what exactly is an external aquarium filter? Simply put, it is a filter that sits outside of the aquarium, usually in the cabinet or stand below. It works by pumping water from the tank into the filter, where it passes through various types of filter media that remove debris, excess food, and fish waste. The filtered water is then returned to the tank, providing a clean and healthy environment for your fish to thrive in.

There are many benefits to using an external aquarium filter over other types of filters. For starters, they are typically much more powerful and efficient than internal filters. This means that they can handle larger aquariums and more fish without becoming overwhelmed. They also provide better water circulation, which helps to prevent dead spots in the tank where debris can accumulate.

Another advantage of external filters is that they are very easy to maintain. Unlike internal filters, which can be difficult to access and clean, most external filters have removable filter trays that can be quickly and easily cleaned or replaced. This means that you can keep your filter running at optimal performance with minimal effort.

Of course, external aquarium filters do come with some downsides too. For one, they can be more expensive than other types of filters. However, the benefits they provide are well worth the investment for serious fish keepers. Additionally, they can be a bit more difficult to install, especially if you are new to aquarium keeping. However, with some patience and guidance, most people can figure it out.

When shopping for an external aquarium filter, there are a few things to keep in mind. First and foremost, you need to choose a filter that is appropriate for the size and type of aquarium you have. A filter that is too small for your tank will not be effective, while one that is too large may create too much water flow and stress your fish.

Another factor to consider is the type of filter media you want to use. There are many different types of media available, including mechanical, biological, and chemical. Each type serves a slightly different purpose, so you may want to research your options before making a decision.

Finally, you should also consider the noise level of the filter. Some external filters can be quite loud, which can be annoying if your aquarium is in a quiet room. However, many newer models are designed to be quiet and unobtrusive.

An external aquarium filter is an essential component of any fish tank. It can help to keep your fish healthy and happy by providing a clean and stable environment. While they may be a bit more expensive and difficult to install than other types of filters, the benefits they provide are well worth the investment. Just be sure to choose the right size filter and filter media for your aquarium, and you’ll be well on your way to successful fish keeping.
