The best filter for 55 gallon aquarium is necessary to keep the tank clean and healthy. You may already own an aquarium, but may still have not purchased a filter. However, we’ll tell you why a filter is essential. The filter catches all the trash that gathers via the intake tube. This is a type of mechanical filtration, and many filters use a pad, or a sponge to block the litter from getting back into the tank.

Also, this equipment is required for the chemical filtration of certain substances, for example; activated carbon enters the tank to manage chemical wastes generated by the fish. Cartridges and inserts manage the chemical filtration in the filter. The filter is also responsible for biological filtration. This filtration happens when natural bacteria accumulate in the tank, and the filter removes ammonia and other such deleterious chemicals.


How Does A Filter Work?

This guide mainly focuses on the best filter for 55 gallon aquarium, but before we move on to reviewing the top 10 models, it is essential to know how a filter works. This external aquarium filtration system can be permanently placed in an aquarium cabinet, where it won’t detract the tank’s image.

This filter is powered by an impeller which withdraws tank’s water via a tube, makes it pass through different sections of filter media, enclosed in several chambers inside a canister.

Then it discharges the water back into the tank using another tube. There are three significant filtrations that the filter takes care of, and we will be elaborating upon them;

1. Mechanical Filtration

It is the primary form of filtration and implicates the physical ejection of solid waste substances from the water. This is fulfilled by using a sponge, or a pad which catches the solid waste particles, as the water passes through the filter.

2. Chemical Filtration

It is a process which includes the ejection of dissolved substances, and heavy metals from the aquarium’s water. It is generally achieved by utilizing activated carbon filter media.

3. Biological Filtration

This process involves the removal of Ammonia (NH3) and Nitrite (NO2) from the aquarium’s water. It is necessary to remove these natural chemicals as they can prove to be harmful to your fish.

Canister filters are mostly preferred, and are more popular than other filters because they can fit more filter media, and thus efficiently perform these three kinds of filtrations. But note that canister filters are more costly than other types of filters used for the same tank sizes.

These filters are mostly required for medium to large aquariums (at least 30 gallons or more). These are usually chosen because they offer one of the best filtration systems.

How To Choose The Best Filter For 55 Gallon Fish Tank?

There are a few important things you need to keep in mind before purchasing the best filter for 55 gallon fish tank.

If you buy a smaller sized filter for a tank which is more than 50 gallons, the tank will exert too much pressure on the filter, and will end up malfunctioning. If you get a filter which is larger than the required size, you will be unnecessarily spending your money. That’s why we recommend you to check your tank’s capacity and buy an accurate sized filter.

2. How Much Money Are You Willing To Spend?
