Why a 20 Gallon Aquarium Filter is a Must-Have
As an avid aquarium enthusiast, I have come to learn the importance of having a reliable filter for my tank. When I first started out with a small 5 gallon tank, I thought a filter was just an unnecessary expense. However, as I upgraded to a larger 20 gallon tank, I quickly realized how vital a good filter is for the health and well-being of my aquatic pets.
First and foremost, an aquarium filter helps to remove harmful toxins and waste from the water. Fish produce waste in the form of ammonia, which can quickly build up and become toxic if not properly filtered out. A 20 gallon tank may seem like a small space, but with even just a few fish, the amount of waste produced can be significant. Without a filter to remove these toxins, it can lead to sick and even dead fish.
In addition to removing toxins, filters also help to keep the water clean and clear. This not only makes for a more aesthetically pleasing tank but also promotes better oxygenation for the fish. A dirty tank can quickly become cloudy and develop algae growth, which not only looks unsightly but can also be harmful to your aquatic pets.

My Buying Guide on ’20 Gallon Aquarium Filter’
As an experienced aquarist, I understand the importance of having a good filtration system in an aquarium. A 20 gallon aquarium is a popular size for many hobbyists, and finding the right filter for it can be overwhelming. After extensive research and personal experience, I have compiled this buying guide to help you make an informed decision when purchasing a 20 gallon aquarium filter.
Types of Filters
There are three main types of filters for aquariums: mechanical, chemical, and biological. Mechanical filters remove debris from the water, chemical filters remove impurities and odors, and biological filters promote the growth of beneficial bacteria. For a 20 gallon aquarium, I recommend using a combination of all three types to ensure optimal water quality.
HOB (Hang-On-Back) Filters
HOB filters are the most commonly used type for a 20 gallon aquarium. They hang on the back of the tank and have different compartments for each type of filtration media. They are easy to install and maintain, making them ideal for beginners. When choosing a HOB filter, look for one with adjustable flow rate and multiple filtration stages for better efficiency.
Canister Filters
Canister filters are another popular choice for larger tanks like a 20 gallon aquarium. They sit outside the tank and use tubing to pump water in and out of the tank through different filtration media. Canister filters offer superior filtration compared to HOB filters but can be more expensive and require more maintenance.
Sponge Filters
Sponge filters are affordable and easy to use but may not be suitable as the main filter in a 20 gallon aquarium. They are best used as secondary or backup filters to provide additional biological filtration. Sponge filters work by trapping debris in their porous surface while promoting bacterial growth.
Flow Rate
The flow rate is an important factor to consider when buying an aquarium filter. It determines how much water is filtered per hour and should be at least four times the tank’s volume (80 gallons per hour for a 20 gallon tank). Too much or too little flow can affect water quality and stress fish.
Filtration Media
Before purchasing a filter, make sure it comes with appropriate filtration media or has space to add your own. It’s recommended to have mechanical media (sponge or floss), chemical media (activated carbon), and biological media (ceramic rings or bio balls) in your filter for optimal results.
Noise Level
No one wants a loud buzzing or humming noise coming from their fish tank all day long. When choosing an aquarium filter, consider its noise level as some models can be quite loud. Look for ones with quiet operation features such as rubber feet or sound-dampening materials.
In Conclusion
Finding the right filter is crucial in maintaining a healthy environment for your fish in a 20 gallon aquarium. Consider factors like type, flow rate, noise level, and filtration media when making your decision. Remember that regular maintenance is also essential in keeping your filter functioning properly. With this buying guide, I hope you can make an informed decision that will benefit both your fish and your wallet in the long run.
