It has 3 media trays that are entirely flushed against the sidewalls of the filter. This prevents the water from bypassing the filtration media. The FilStar intakes the water from the bottom and releases it from the top. Due to the up-flow design, gravity does the work of sorting out the bigger particles. These particles then settle at the bottom of the filter.

The FilStar has a flow rate of 350 gallons per hour and is suitable for tanks with a capacity of up to 175 gallons. It comes with self-priming and has a quick disconnect feature.

This canister filter also has a spray bar that you can use to adjust the output flow. It features an O ring at the opening that helps to keep the filter sealed and prevent leaks.

Things to Consider When Choosing a Canister Filter

Below are the top 3 things you must consider when choosing a canister filter:

  • Tank size

The top canister filters are not created alike. They differ with respect to the tank size. Therefore, you must check the size of your aquarium’s tank before purchasing a filter as the filter’s performance depends on the tank size. If you are unsure of this information, you can reach out to the customer support team for assistance.

  • Filter flow rate

The first thing you must enquire about is the filter flow rate. Every fish tank canister filter comes with manufacturer’s specifications. You must check the specs and buy a model that is most suitable for your tank. It is better to choose a filter with a higher flow rate as it will ensure faster completion of the filtration process.

  • The motor

The motor of the canister aquarium filter helps it to pump the water into its filtration system. It, therefore, essential to buy a product that is reliable, efficient, and operates quietly.

Frequently Asked Questions

Buying the best canister filter for your marine friends can be a daunting task. Buyers are often riddled with many questions in their minds. To help you in your search, we have compiled answers to some of the most common, yet pertinent questions frequently asked by buyers. So let us get started!

How does canister filter work?

Canister filters make use of a plastic box called a canister to hold trays of various filter media. 
Canister filters make use of a plastic box called a canister to hold trays of various filter media. 

With the help of tubes and an electric pump, the water gets pulled out of the aquarium. It is then pushed through the different filter media trays and is finally sent back into the tank through another tube. 

The direction of the water flow differs based on the brand and model. It can be top-to-bottom, bottom-to-top, outside-in, center-out, or back-to-front.
 
While the water passes through the filter media, its membranes will trap the debris and micro-organisms in it and allow only clean water to flow back into the tank. Depending on the type of filter media you opt for your canister filter, it will perform chemical, biological, and/or mechanical filtration.

It is important to note that although most models have an in-tank pump to propel the water into the canister, there are a few models that have mounted motors. However, they both work similarly.

How often to clean the canister filter?

As canister filters trap the impurities and debris, they are susceptible to clogging. Therefore, it is necessary to clean the canister filter to ensure smooth operation and provide a safe environment for the fishes and other inhabitants of your aquarium.

As many of the best aquarium canister filters use mechanical, biological, and chemical filtration systems, it is essential to clean them all. 

The mechanical filters must be ideally cleaned once every month to remove the trapped solid particles and debris. Replace or clean the chemical filters when you notice the water in your aquarium turning cloudy. Nonetheless, they must also be cleaned every 2 months. Lastly, you must also replace or clean the biological filters once in 2 months.

Lastly, you must also replace or clean the biological filters once in 2 months.

How long do canister filters last?

Most filters and especially the ones listed in our aquarium canister filter review last for years. The most important thing to note in order to prolong the canister filter’s life is to clean and maintain the individual components of the filter well. Apart from the filter media, you must also clean the impeller, canister casing, fasteners, and hose to increase the filter’s life.

Use a scrub pad or toothbrush to get rid of the algae sitting on the canister parts. To clean the filter hose, use a sump pump. Immerse the hose in a solution of vinegar or hydrogen peroxide and use the pump for rushing the water through the hose.

What is the quietest canister filter?

Filtering your aquarium can become a noisy affair if you do not select the right filter. However, silent filters do exist, and there is more than one option to choose from.

Canister aquarium filters by nature make less noise compared to other types of filters. The efficient design and mechanism used to turn the water through the tubes in such filters ensure minimal noise without compromising the performance. 

As canister filters use tubes to push the water back into the tank, you will not hear the sound of water splashing at all. Moreover, a few of the latest models use sound-dampening technology to bring down the noise levels even more.

Among the products that we have mentioned in our aquarium canister filter review, the Eheim classic is the quietest canister filter. So if your current filter is vibrating and making humming noises, replace it with a quieter model to restore your peace of mind.

What is the best canister filter?

Different models have different features. Therefore, the best canister filter for you ultimately depends on your needs and the type of fish tank you have.

After analyzing the top 10 products in great detail in our aquarium canister filters review, we find that the Penn-Plax Cascade is the best canister filter out there in the market. Not only does it have a price tag that will not drain your pockets too deeply, but it also does its job very well! It is easy to install and maintain, and the valves have a shut-off control feature that prevents leaking.

However, if you are ready to spend a few extra bucks, we suggest going for the Fluval external filter. Its cleverly designed filtration path and high flow rate deliver an excellent performance. Its superior build quality, easy availability of replacement parts, and a 3-year warranty are some of the other positives of this product.

Conclusion

An aquarium can light up even the dullest room and make it look so much better. However, to prevent it from getting dirty and maintain your fishes’ health, it is imperative to install a suitable aquarium canister filter.

We hope that our review of the 10 best canister filters for aquariums has equipped you with all the information that you need to make your choice. All the products mentioned here are the top-rated canister filter available in the market today. Apart from being durable, they are also efficient.
