The Importance of an External Fish Tank Filter

As an avid fish hobbyist, I have learned firsthand the importance of having a good filtration system in an aquarium. While there are various types of filters available, an external filter has proven to be the most beneficial for my fish tanks. Here are a few reasons why I believe an external filter is necessary:

1) Improved Water Quality: The primary function of a filter is to remove waste and debris from the water, helping to maintain a healthy and clean environment for fish to thrive in. An external filter has a larger surface area and stronger filtration capacity compared to other types, which results in better water quality.

2) Increased Oxygenation: Fish need oxygen to survive, and an external filter helps to increase the oxygen levels in the water by creating movement and turbulence. This is especially important for larger tanks with more fish, as they require more oxygen.

3) Efficient Biological Filtration: An external filter typically contains multiple compartments for different types of filtration media. This allows for efficient biological filtration, where beneficial bacteria can grow and break down harmful waste products into less toxic substances.

4) Easy Maintenance: External filters are designed for easy maintenance. They can be easily accessed outside of the tank, making it less disruptive

My Buying Guide on External Fish Tank Filter

As a fish tank owner, I understand the importance of maintaining a clean and healthy environment for my aquatic pets. One essential tool that has made my life easier is an external fish tank filter. It not only keeps the water clean but also helps in maintaining the overall balance of the tank. After trying out various brands and types, I have come up with this buying guide to help fellow fish enthusiasts make an informed decision.

Types of External Fish Tank Filters

Before diving into the features and specifications, it is important to understand the different types of external filters available in the market.

1. Canister Filters – These are the most popular type of external filters that use a canister to hold different filtration media such as mechanical, biological, and chemical for maximum efficiency.

2. Hang-On-Back (HOB) Filters – As the name suggests, these filters hang on the back of your aquarium and use an intake tube to draw water from the tank through filtration media.

3. Power Filters – Also known as internal filters, these are submerged in the aquarium and use a pump to circulate water through filtration media.

Filtration Capacity

The most important factor to consider while buying an external fish tank filter is its filtration capacity. It should be able to handle at least four times the volume of your tank per hour for optimal results. For example, if you have a 50-gallon tank, go for a filter with a minimum flow rate of 200 gallons per hour (GPH).

Filtration Media

The type and quality of filtration media used in an external filter play a significant role in maintaining water quality. Look for filters that offer multiple stages of filtration, including mechanical (for removing debris), biological (for beneficial bacteria growth), and chemical (for removing impurities).

Noise Level

Having a noisy filter can be extremely annoying, especially if your fish tank is placed in your living space. Look for models with noise-reducing features such as rubber feet or sound-absorbing materials.

Size and Maintenance

External filters come in various sizes depending on their filtration capacity. Consider the size of your aquarium and available space for installation before making a purchase. Also, look for models with easily accessible parts for cleaning and maintenance.

Brand Reputation and Warranty

When investing in an external fish tank filter, it is important to choose a reliable brand with good reviews from other users. This ensures quality performance and durability. Additionally, look for models that come with a warranty to cover any manufacturing defects.

In conclusion, an external fish tank filter is an essential tool for maintaining a clean and healthy environment for your aquatic pets. Consider factors like type, filtration capacity, noise level, size/maintenance requirements along with brand reputation before making your final decision. With this buying guide and some research, you can find the perfect external filter for your fish tank needs. Happy shopping!
