The Magnum Polishing Internal Canister Filter from MarineLand is one of the most versatile devices on this list as it offers two distinct filtration options to choose from. You can choose to have your tank’s water filtered by either the standard three-stage filtration system or its unique water polishing option.
The three-stage filtration system involves a mechanical, chemical, and biological filtration stage. Each of these stages uses high-quality materials to give you an adequate level of water cleaning. For example, this device uses premium activated carbon in the chemical filtration system, which is excellent at removing odors and impurities in water.
However, if you feel like the first stage of water filtration was not enough to clean your tank, all you have to do is switch to this filter’s second “water polishing” option. This system uses an inbuilt pleated micron cartridge to remove debris, efficiently turning dirty water crystal clear.
This filter from MarineLand does not compromise on power either. Thanks to its robust water flow rate of up to 290 GPH, it can work well in large tanks up to 97 gallons capacity.
However, all of it comes at a price, as you will have to clean the micron cartridge and replace the internal filters at least once a month. Also, these filters require you to make an aftermarket purchase, which makes maintaining this filter slightly expensive if you are on a budget.
The Magnum Polishing Internal Canister Filter from MarineLand is a versatile device that offers two unique filtration methods. The three-stage filtration is excellent at removing unwanted elements, while the water polishing option works to make water crystal clear. The filter is also potent, but it does require regular maintenance, which might be a hassle for beginners.

You won’t have to worry about running it at total capacity either, as the motor running the EA Performance filter’s cleaning system is well built and housed in a sturdy assembly. However, while the motor assembly is solid, the rest of the filter is not as strong, and you should avoid dropping it.

The filter comes with everything you will need to set it up. Items such as quick disconnect valves, pump locking heads, water intake/output connections, hoses, and much more are included in the box.
However, all these features and parts add to the filter’s overall weight, which is a hefty 14.9 pounds. Due to this, you will probably need to place it on the ground or a separate table/stand.

Things to Consider While Choosing a Filter for a 55-gallon Fish Tank
– Filtration Stages
An essential factor you should look into when buying an aquarium filter is the stages of filtration it offers. Typically, an aquarium filter offers three different types of filtrations, namely mechanical, biological and chemical. Let’s go over them quickly.
Mechanical Filtration: Mechanical filtration refers to removing large particles of dirt, gunk, debris, and fish excretion. These make up the majority of the visible waste in your aquarium and need to be removed immediately to avoid any infections in your pet. Aquarium filters come equipped with sponges or filter paper to trap these particles. You can simply wash the mechanical filtration element for reuse.
Biological Filtration: Apart from gathering dust particles, filter sponges and mesh paper are ideal sites for the colonization of good bacteria. These bacterial colonies balance the ammonia and nitrate levels in the water while also hindering the growth of algae. Aquarium filters also come with bio balls, which enhance bacterial growth for better filtration.
Chemical Filtration: Lastly, chemical filtration is necessary to remove heavy metals, toxins, and odor from your aquarium water. It is achieved by using activated carbon, which absorbs the harmful elements present in the water to provide a suitable climate for your fish.
If you want a well-rounded cleaning and hygiene in your tank, we recommend getting a filter that follows all three processes to keep your fish healthy. Modern filters offer multiple layers of all three filtration types to make your dirty aquarium water crystal clear.
– Additional Features
Along with the basic filtration system, many large 55-gallon filters also offer various additional features. It can range from utility functions like a hang-on design to filtration boosting ones like a water polishing system.
So, look for filters that will be useful to you in your aquarium. For example, if the top of your aquarium tends to have oil build-up, find a filter with a surface skimmer option to keep the surface clean. Or, if you don’t want to purchase an additional device to clean your aquarium’s substrate, you can get a filter with a gravel cleaner built into it.
– Water Flow Rate
The water flow rate of a filter refers to the volume of water that the filter can process in a specific duration. It is usually calculated in gallons per hour (GPH) and is very important for managing your aquarium efficiently.
While it may seem like having more GPH is better, this is not always true. The higher output will surely make the filter faster at cleaning water, but it may be unnecessary for regular use and damage your aquarium’s ecosystem. That is because fast-flowing water can suck in delicate fish and plants, which can injure them.
For most 55-gallon aquariums, having a filtration unit with a flow rate of at least 220 GPH is sufficient for maintaining clean water. Anything over 300 GPH will be extra and will not be needed for regular usage. So, be sure to consider the water flow and if it is suited to your aquarium’s plant and fish before buying an aquarium filter.
1. How Many Filters Do I Need for a 55-Gallon Tank?
When it comes to 55-gallon tanks, it is advised to use a filter with a water flow rate of at least 220 GPH. A good rule of thumb you can follow when deciding how powerful your filter should be is to multiply your tank’s capacity by four.
2. Is it Okay to Run Your Filter for Extended Hours?
No, you can’t really over-filter an aquarium. However, it is possible to under-filter an aquarium, which can be very harmful to your aquarium’s plants and fish as it leads to bacteria and waste build-up.
3. How Often Should You Clean a Canister Filter?
Canister Filters are enclosed devices that have internal canisters that filter the water. These filters do not require much cleaning and can run for months without requiring treatment or replacement. It is advised to change the internal canisters every three to four months to ensure proper hygiene in your fish tank.
4. How Do I Know If My Aquarium Filter Is Clogged?
When your aquarium gets clogged, it becomes unable to eliminate excessive ammonia and nitrates from the water efficiently. It can severely affect your pets, and you will start to notice a decline in appetite, reduced energy, and loss of coloration in your fish and shrimp. The general signs become significant within 1-2 weeks, and if the filter goes untreated for long, the nitrate buildup can weaken your fish’s immunity.
5. Are Canister Filters Worth the Money?
Yes, Canister filters are worth the extra money as they are much more reliable when filtering out freshwater and saltwater aquariums. They offer powerful filtration and many unique features, such as gravel cleaners, while still requiring less maintenance. They are especially suitable for larger tanks ranging from 50 gallons and above as these benefits make it much easier to keep aquariums clean.
It is crucial to have good quality and trustworthy 55-gallon fish tank filter system to ensure that your tank stays clean. Choosing the wrong filter can not only turn out to be a waste of money but can also cause harm to your aquarium’s flora and fauna.
