People have a lot of questions about aquarium filters, and there's a lot of conflicting information out there.

A lot of people give up on keeping an aquarium because they're not sure how to set it up or what kind of filter to buy.

We've put together a list of the most frequently asked questions about filters for 55-gallon aquariums. This will help you decide which filter is right for you and your tank.

How big of a filter do I need for a 55-gallon tank?

The size of the filter should be rated for at least 4 times the volume of your tank, so for a 55-gallon fish tank, you would need a filter rated for at least 220 gallons per hour (GPH). It's important to make sure the filter is strong enough to provide adequate filtration and circulation throughout your tank.

Does a 55-gallon tank need an internal canister filter?

An internal canister filter is not necessary for a 55-gallon tank, but it could be beneficial. Canister filters are typically used in larger tanks to provide more efficient filtration. They offer more space for media and usually have higher flow rates than other types of filters, which can help keep the water clean and healthy.

Is it OK to have two filters in one tank?

It is generally okay to have two filters in one tank. However, it is important to consider the size of the tank and the type of filter you are using. If the tank is small, having two filters may be too powerful for the tank and can cause water movement that could disturb fish or plant life. If both filters are of the same type, they may be competing for food sources and bacteria colonies which can make them less effective.

Which is the best filter for aquariums?

The best filter for an aquarium depends on the size and type of tank, as well as the type of fish and plants you are keeping. Generally speaking, a good filter should provide adequate filtration to keep your tank clean and healthy. This includes removing debris, uneaten food, and waste from the water while also helping to maintain a balanced pH level.

What are the 3 types of aquarium filters?

There are three main types of aquarium filters: mechanical, biological, and chemical. Mechanical filters remove solid particles from the water by trapping them in a filter media such as foam or floss.

Biological filters provide a place for beneficial bacteria to colonize, which helps to break down organic waste and ammonia. Chemical filtration uses activated carbon or resins to remove dissolved toxins from the water.

How do I choose the right filter?

Choosing the right filter for your needs depends on what kind of filter you’re looking for. When it comes to water filters, think about the type of contaminants that are present in your water source and make sure the filter is capable of removing them.

Take into account how often you plan on changing out your filter since some filters need more frequent replacement than others.

Research different brands and models to compare prices and features before making a decision. This will help ensure that you get a quality product that meets all your needs without breaking the bank.

What is the most common aquarium filter size?

The most common aquarium filter size is usually determined by the size of the tank. For example, a 10-gallon tank would typically use a filter with an adjustable flow rate of up to 100 gallons per hour (GPH). This allows for adequate filtration while still providing enough water movement to keep the tank healthy.

How long does a filter last in a tank?

The lifespan of a filter in a tank depends on several factors, such as the size of the tank, the type of filter, and how often it is cleaned. Most filters will need to be replaced every 4-6 weeks.

Can you clean and reuse fish tank filters?

Yes, you can clean and reuse fish tank filters. The process of cleaning a filter is relatively simple and straightforward. First, remove the filter from the tank and rinse it in water to get rid of any debris or dirt that has built up on it.

Then, soak the filter in a solution of one part white vinegar and four parts water for about 30 minutes. This will help to break down any organic matter that may have accumulated on the filter. Finally, rinse off the filter with fresh water and then reassemble it back into your aquarium.

What is the most common type of aquarium filter?

The most common type of aquarium filter is a hang-on-back (HOB) filter. HOB filters are easy to install and use, and they provide effective filtration for aquariums of all sizes. They consist of a motorized pump that hangs on the back of the tank, along with a filter media chamber that houses mechanical and biological filtration media.

What happens if you use the wrong size aquarium filter?

Using the wrong size aquarium filter can have serious consequences for your fish and their environment. If the filter is too small, it won't be able to handle the amount of waste and debris that accumulates in the tank.

This can lead to a buildup of toxins and an unhealthy environment for your fish. On the other hand, if the filter is too large, it will create a strong current that can disturb delicate plants and invertebrates in your tank. In addition, a larger filter may be more expensive to operate due to increased energy usage.

Does charcoal clear aquarium water?

Yes, charcoal can be used to clear aquarium water. Charcoal is a type of activated carbon that is used in many aquarium filters and can be beneficial for removing impurities from the water. It works by trapping organic compounds, metals, and other contaminants on its surface. The charcoal will eventually become saturated with these impurities, so it should be replaced regularly

Which is better internal or external aquarium filter?

It depends on the type of aquarium you have and what kind of filtration system you prefer. Internal filters are easier to install and can be more cost-effective, but they don’t provide as much biological or mechanical filtration as external filters.

External filters are usually more powerful and offer more effective filtration, but they may be more expensive and require additional installation steps.

What aquarium fish don't need filters?

Many aquarium fish can survive without a filter, although it is not recommended for the health of the tank. Fish that do not require filters are generally smaller species such as tetras, guppies, and rasboras. These fish produce relatively little waste and have lower oxygen requirements than larger species.


In conclusion, having the right fish tank filter for a 55-gallon aquarium is incredibly important as it not only helps to keep the tank clean and healthy but also enhances its aesthetic appeal. But with so many options on the market, it can be difficult to know where to start and which type of filter would work best for you.
