Review Overview

Last update on 2024-06-08 / Affiliate links / Images from Amazon Product Advertising API

After trying seven different canister filters in my home aquariums, I gave them ratings according to how well they performed overall.

I was most impressed with my experience with Fluval filters that I tried out. I tried two different canisters made by the German manufacturer tested, the FX6 as well as the 407 and FX6. Both of them were silent and efficient. I was awed by all the features of these canisters.

But, it must be mentioned that the Eheim Classic canister made an impressive performance despite the fact that it’s a less complicated design than the more elaborate Fluval filters. If you’re looking for a classic design and simplicity, this canister is for you.

The Aqueon Quietflow was the standout among the budget filters. It is the perfect balance of low cost versus features.

The Oase Biomaster did a decent job. It comes with unique features such as a built-in heater, and an extremely sturdy handle on the motorhead. These features make the Biomaster stand out.

Description of Canister Filter For 4eet Aquarium

A canister filter for a 4ft Tank can be described as a sort of aquarium filter that is made up of a cylinder. It is typically made from plastic.

The lid on the canister protects it and it is filled with the media to filter. There are valves, pipes, and other components that are required for the proper running of the device.

Canister filters are utilized to clean the water in large aquariums that have heavy fish or where you wish to create a perfect habitat that is ideal for fish.

They are stronger and more efficient than other kinds of filters because of their ability to not only cleanse water, but also accomplish other tasks like sterilization, or even removing smells (due to the activated carbon).

In terms of disadvantages, Canisters are big, therefore they consume larger spaces than many other kinds of aquarium filters.

But, this drawback should not be misinterpreted as a price since they can be extremely inexpensive depending on the model you purchase. Small or large-capacity models can cost more while smaller models are cheaper, but they are still top-quality devices.

Types of Canister Filter For 4 Feet Aquarium

There are two kinds of filters for canisters. The one that is mounted on top is the top canister filter, which is mounted on the top of the aquarium and needs a minimum of 6″ to allow flowing water.

The second kind is more widespread, however: it’s an under-gravel filter, which is located beneath the aquarium.

This kind of filter has many benefits over the other types of filters since it doesn’t occupy space or require any additional equipment or maintenance. However, there are disadvantages in certain circumstances.

Installation: Getting this filter set up isn’t easy.

The hoses can be a bit clunky and erratic when trying to set them up. They’re stiff and quite hard to bend. They must be curled around the curved holders to be placed over the tank’s rim.

The hoses must be bent around the base of the holder, and the top piece must be secured to hold it in position. It’s simpler said than done.

I would suggest getting someone to assist you in this task to ensure that one person keeps all the pieces in place while another person can connect the pieces of the holder.

It comes with a large instructional manual that is very thorough when you purchase this filter. I strongly recommend taking this out and studying the entire guide before starting.

Best for large aquarium setups that range from 100-200 Gallons (379-757 757 liters).


  • Immense bio media capacity
  • Strong but quiet pump
  • Simple maintenance


  • The installation of hoses is a hassle. install

Installation: Similar to the FX6 My main complaint about this filter is with the installation.

It’s not as difficult to install the filter up and running however I highly suggest reading the manual before you start.

This filter comes with hoses as well as holders that are comparable to the ones used in the FX6s. They’re simpler because the hoses are smaller in size, but the process of installing them can be an issue.

Additionally, the instructions for installation did not include the necessary information on how to turn on the water flow in the valve that connects quickly, which made it a pain.

This filter has amazing reusable mechanical media. I would like all filters to come equipped with this sponge. They’re huge and can take lots of gunk from the water.

Best for 40-55 gallon (151-208 liter) tanks.

Installation: Getting this filter installed is very easy.

It is the Eheim Classic is just a large canister that is open and filled with filter media in a loose state.

The majority of the time, it’s just washing the media clean and then placing it into the container.

I was amazed at how simple it was to have the intake, hoses, and outflow setup.

The hoses are extremely flexible and won’t snag against them.

The quick-connect valves are plugged into the hoses in line and just took me a few minutes to attach them.

Both outlets and intake tubes are curving so that they can easily slide over the sides of the tank. They were the easiest to install in the group.

The only downside to this particular filter is it isn’t equipped with any physical filter media. However, as the canister is essentially a cylinder, it’s difficult to cut matten filter media and fit inside.

Ideal for: The Eheim Classic is best suited for tanks that hold 30-40 gallons (113-151 liters) tanks.

I’ve been running this filter for a while in my forty-gallon plant rainbow fish tank and I’ve been very pleased with it.

  • Simple maintenance

  • Only a few mechanical mediums are available.

Installation A: This Oase canister comes with a unique pre-filter. It’s basically a tube made of plastic with an array of tiny, black sponges similar to those that are used as pre-filters for hang-on-the-back filters.

They are intended to remove debris and algae prior to it entering the body of the canister. This is fantastic, however, these sponges could get extremely clogged. Therefore, be sure to wash them out frequently.

It also comes with built-in heaters which no other canisters have. It’s a 200-watt glass heater that is attached to the bottom of the motorhead.

The pre-filter and built-in heater make it more difficult to get the filter in place however I believe they’re worthwhile.

The main body of the canister has four media baskets that stack. Three of them are made up of reusable sponges and the fourth one is lined with a biomedia plastic that’s the bio ball and ceramic noodles.

Usually, I complain that filters do not have enough physical media. However, I believe that this filter is a bit too full. If I wanted to use this filter for a long in the future, I’d remove any sponges to replace them with bio media.

The best choice for This Oase filter is ideal for tanks that are 40-50 gallons (151-208 1 liter) tanks.


  • Quietest filter tested
  • Built-in heater
  • A wide range of mechanical filter media
  • Sturdy motorhead handle

Installation: There are many choices when it comes to setting up this type of filter.

This Aqueon Quietflow is equipped with the following three outflow accessories.

  • Directional nozzle
  • Spray bar
  • Water polishing unit

The directional spray nozzle and bar are common to what is found in most canister filters. However, the water polishing system is unique to Quietflow.

It’s akin to a traditional hang-on-the-back type filter. It’s located on the edge of the tank, with the outflow pipe attached at the base of the tank.

As the water returns from the canister back to the tank it flows through a cartridge filter that comprises an ultra-fine polishing pad, as well as carbon that is attached to a frame made of plastic.

I’m not a fan of this tank. It’s a huge, hulking object at the rear of the tank. One of the advantages that a tank has is its capability to reduce the visible area of the filters. This canister completely eliminates the need for it.

Additionally, I do not like the idea of being enticed to buy expensive cartridges for filtering. I’d rather put to the number of sponges I can reuse and avoid this one. I would rather use to use the spray bar.

It was easy to install this canister. It is a typical media basket that stacks.

The hoses worked very well. I put the canister into an aquarium stand that I have in my bowfront 40-gallon aquarium. It was simple to run the hoses from the stand’s back and then up to the rear to the bottom of the aquarium.

The best choice for the Aqueon Quietflow is a great filter for novices. If you’re new to the world of canister filters, I believe this is an excellent initial step.

It’s among the more cost-effective filters which is why it’s an excellent choice for those looking to experiment with the latest filtration method but don’t want to spend a fortune for a test.


  • Many options for outflow
  • Simple to set up
  • Simple maintenance


  • Priming is a major issue
  • Water polishing equipment is a gimmick
  • More mechanical media is required in the canister.

Installation was more difficult to install this filter than the other filters. I was extremely dissatisfied.

The process of setting up everything within the filter is fairly simple. The filter uses stacking baskets, similar to other canister filters. The only thing you have to do is rinse the media before placing it into the filter’s frame.

It’s the outside pieces that cause the most problems.

The hoses used for this filter are extremely rigid and difficult to get them into the location you’d like them. I had a difficult time getting the hoses connected with the outflow and intake pipes too. I tried to coat them using petroleum jelly to ease the process but it was still an issue.

For a final touch, In addition, you must make use of these tiny clamps made of plastic to hold the intake or outflow pipes. These clamps can be difficult to use and can be difficult to close with your fingers. I was not a fan of these clamps at all.

I did enjoy that quick connector that comes with this filter. The two hoses connect to an auxiliary valve which you can use to stop the flow of water. The valve is able to be removed from the motorhead by the lever, which makes maintenance simpler.

However, it was an intense fight to make the hoses able to unwind enough to connect to the valve.

The entire installation process was uncomfortable and awkward. I wasn’t a fan.

Ideal for I would recommend this filter for 40 to 55-gallon (151-208 Liter) tanks.


  • Simple maintenance
  • Features that are competitive at a low cost
  • Great quick connect valve


  • Installation was a challenge
  • A little easier than some filters.
  • Insufficient mechanical media

Installation: Installation was somewhat of a hassle for this filter, too.

The instructions were not very clear and it was up to me to try to find certain issues out by trial and trial.

This filter has an adjustable spray bar that I love, however, the outflow pipe is curved and isn’t able to set the bar deep in the water. I’d like to have an extender to permit you to place it further into the tank.

It was a real struggle to get the bar enough so that it was submerged in water, instead of only over the surface.

I was awestruck that this filter came with an integrated UV sterilizer. This feature is able to eliminate viruses, algae, and bacteria that reside in the water column, and also helps improve water clarity.

The best choice for this filter is ideal to be used with 30-50 gallon (113-190 Liter) filters.

It’s the cheapest of the filters we have tested. It’s the ideal choice for those who are more focused on the price rather than the quality of their filter.


  • Economical
  • The unit comes with an integrated UV sterilizer


  • Instructions aren’t always helpful.
  • The spray bar doesn’t reach far enough
  • The loudest of all filters
  • It was difficult to get started.
