What To Look For In A Fish Tank Canister Filter

Now that we have looked at some of the best canister filters on the market, it is finally time to learn more about what you need to know about these products.

In this section, we are going to look at several things you need to know before you purchase your canister filter.

Motor

An aquarium filter will run constantly, every day, all day.

So, you require a filter that will not use up a load of electricity and of course one that will last you a long time.

The best way you can find a filter like this is by looking out for products that have a UL approval rating.

When it comes to the durability of motors, you will need to look out for a canister filter that has epoxy sealed motors.

This helps to prevent moisture, debris, or dust from damaging the impeller.

Another motor that you can look out for is a magnetic-driven motor.

This basically means that a magnetic coil is used to power the impeller.

On the plus side, these motors are self-priming, so you do not need to siphon water.

The negative side is that these magnetic motors are not sealed like the epoxy sealed ones, and so are less protected from moisture and debris.

Tank Size And GPH

One of the first things you need to consider with a canister filter is how big your aquarium is and compare that to your filter of choice’s GPH or gallons per hour.

This basically means, how much water per hour your filter will turn over.

So, with your own canister filter, you will need a product that can turn over at least 4x the volume of water in your tank every hour.

For example, if you have a tank that is 20 gallons, you will need a canister filter that has a GPH of 80.

It will be wise to look at a canister filter that has a higher filtration, as all filters will naturally lose some flow as soon as you load it with media.

Media Trays And The Filtration Process

The best canister filters out there will have media trays for all of the different filtration stages.

So, the mechanical, chemical, and biological stages will have separate trays in the filter.

If you have a product that has these three trays, you are likely to see better results from your canister filter.

Valves

A canister filter usually has two valves, one is used to control the intake and the other to control the output.

So, when you are considering the valves of your next canister filter, you need to be aware of ones that can be completely closed.

In essence, this means that the water may stay in the hoses, so you can disassemble the filter for maintenance without having to re-prime your filter.

Another thing you should keep your eye out for is the option to disconnect the intake and output hoses.

If you get a canister filter that allows you to do this, you can avoid the need to fill up buckets of water.

Size And Location

Sadly, canister filters can be quite large and unsightly.

So, you need to take care to check the dimensions of your filter.

This is so that you know that you have the space in your tank to put the filter.

Also, where you put your aquarium can have an impact on your day-to-day life.

For example, if it is in your bedroom, you may need to pay extra attention to whether or not your canister filter runs quietly, so your sleep is not disturbed.

Frequently Asked Questions

In this section, we are going to answer some of the most frequently asked questions surrounding canister filters.

So, without further ado, let us begin.

Are Canister Filters Difficult To Maintain?

Canister filters are not really difficult to maintain, they are easy to set up and usually go into the aquarium itself, so you have easy access to them when you need to clean them.

How Long Can Canister Filters Be Off?

A canister filter should not be off for very long.

This is because the media inside the filter can die off if it does not get the oxygen it needs.

So, if your filter is off for more than one or two hours, it is a good idea to open the trays and rinse the medium before putting it back on.

If you do not do this, you might end up pumping poison into the aquarium and make things much worse.

How Often Should You Change a Canister Filter?

The canister filter itself does not get replaced unless the device becomes faulty.

But, the medium inside the filter should be replaced every few weeks and at this time you should at least give the filter housing a quick rinse.

If you see any debris or algae, you should make sure that you clean that out too.

Are Canister Filters Quiet?

This type of filter is one of the quietest out there.

The tubing and design of these filters are so perfect that they are able to operate almost silently and still perform as they should.

Final Thoughts

That is all for this article, we hope that you have learned everything that you need to know about canister filters.

There is a lot of information out there about these products, and it is not a purchase you make lightly.

The death of your fishy friends is not something to be taken lightly.

So, make sure to choose a canister filter with good ratings, an excellent reputation, and of course all the features that you need for your aquarium.
