Why I Believe a Filter is Necessary for a 20 Gallon Fish Tank

I have been an avid fish keeper for many years and have had various sized tanks. Through my experience, I have learned that having a filter is crucial for maintaining a healthy and balanced environment for fish to thrive in, especially in a 20 gallon tank.

Firstly, a filter helps to remove excess waste and debris from the tank. In a closed system like an aquarium, waste can quickly build up and become toxic to the fish. Having a filter constantly running helps to keep the water clean and clear, providing a healthier environment for the fish.

Secondly, filters also aid in maintaining proper oxygen levels in the tank. Fish need oxygen to survive and without proper circulation, the water can become stagnant and low in oxygen. A filter helps to keep the water moving, allowing for gas exchange at the surface of the water.

Moreover, filters provide biological filtration which is essential for keeping ammonia levels in check. Ammonia is released through fish waste and can be highly toxic if not properly filtered out. A biological filter works by cultivating beneficial bacteria that break down ammonia into less harmful substances.

In addition to these practical reasons, having a filter also makes maintenance easier as it reduces

My Buying Guide on ‘Filter For A 20 Gallon Fish Tank’

As a fish enthusiast, I understand the importance of having a good quality filter for a 20 gallon fish tank. The right filter not only keeps the water clean and clear but also provides a healthy environment for your fish to thrive in. After years of trial and error, I have compiled this buying guide to help you choose the perfect filter for your 20 gallon fish tank.

1. Type of Filter

The first thing to consider when buying a filter for your 20 gallon fish tank is the type of filter. There are three main types of filters – power filters, canister filters, and sponge filters.

  • Power Filters: These are the most common type of filter used for small to medium sized tanks. They hang on the back of the tank and provide mechanical, chemical, and biological filtration. They are easy to install and maintain.
  • Canister Filters: These are more powerful than power filters and are ideal for larger tanks. They sit outside the tank and provide superior mechanical, chemical, and biological filtration. They require more maintenance but offer better filtration.
  • Sponge Filters: These are simple yet effective filters that use an air pump to draw water through a sponge. They provide biological filtration and are best suited for small tanks with low bio-load.

2. Filtration Capacity

The next important factor to consider is the filtration capacity of the filter. A general rule of thumb is that your filter should be able to process at least four times the volume of your tank per hour. So, for a 20 gallon tank, you need a filter with a minimum flow rate of 80 gallons per hour (GPH). This ensures efficient removal of waste from your tank.

3. Maintenance

No one likes spending hours cleaning their fish tank or their filter. That’s why it’s important to choose a filter that is easy to maintain. Consider factors like how often it needs cleaning, if replacement parts are easily available, and if it comes with an instruction manual.

4. Noise Level

If you’re like me and have your fish tank in your bedroom or living room, then noise level is an important factor to consider when buying a filter. Some filters can be quite loud due to their powerful motors or air pumps which can be disruptive especially at night.

5. Budget

Last but not least, consider your budget when choosing a filter for your 20 gallon fish tank. While cheaper options may seem enticing, they may not always offer good quality filtration or may require frequent replacement parts which can add up in cost over time.

In conclusion, choosing the right filter for your 20 gallon fish tank requires careful consideration of factors like type of filter, filtration capacity, maintenance requirements, noise level and budget. With this guide in hand, I’m confident you’ll be able to make an informed decision on which filter will work best for your specific needs.
