The 106 is a fairly small filter intended for smaller sized aquariums. It comes with a number of features that make it appealing but how does it measure up against other options? Let’s not waste any more time and take a look at the main features and benefits that the Fluval 106 Canister filter offers.

No Clogs

A problem that many aquarium filters seem to experience is that they clog often. Obviously this is not ideal, something which the Fluval 106 deals with really well. It comes with a great intake strainer and double layer mesh screen to keep debris out of the filter.

The strainer takes debris out of the water before it gets to the main filtering mechanisms, thus taking debris out of the water while also ensuring that the filter does not get clogged.

Good Capacity

Like we mentioned before, this is not the biggest filter, making ideal only for smaller aquarium, but it can handle the smaller ones well. The 106 is designed for aquariums up to 25 gallons in size. On that same note, it has a flow rate of 145 gallons per hour. This is pretty impressive because this means that the Fluval 106 can turn over the water in a 25 gallon aquarium close to 6 times per hour, thus resulting in clear and ultimately clean water.

The special shape of the Fluval 106 means that it can hold up to 30% more water at a time than other circular filters of the same size. It has an adjustable flow rate feature so you can turn the flow rate up or down based on the specific needs of your aquarium.

Easy Prime

It has an instant prime feature. All you need to do is press the primer button once and the filter is totally primed and ready to go, we like this features as after all everyone wants to keep thing’s simple.

Easy Maintenance

Another thing that we personally like about the Fluval 106 is that it is easy to maintain. We do like the single motion lift off clamps which the lid features. To get the lid off, all you need to do is lift the clamps for quick and easy access to the interior of the filter.

This means that cleaning trays and changing the media is quick. Once it comes time to put the lid back on, the clamps ensure a secure fit to make sure that the filter does not leak. The aqua-stop valves which the Fluval 106 filter comes with are also very useful for maintenance.

Simply close the valve to shut off all water flow, allowing you to quickly disconnect the tubing for access. On that same note, setting this bad boy up is also about as easy as it gets. Simply find the appropriate place for the filter, connect the hoses, use the instant primer, and you are good to go.


This filter comes with a noise dampening impeller. This will be important for people who hate the loud noise that some aquarium filters create which is pretty much everyone. Neither you nor your fish want to deal with a really loud filter, something which this filter deals with pretty well.

3 Stage Filtration

Even though it’s a smaller filter it still manages to engage in efficient 3 stage filtration.

It comes with removable, stackable, and customizable media baskets for easy access and customization. The filter media already comes included with the 106 canister filter, which is handy. This filter engages in mechanical, biological, and chemical filtration (more on filter media over at this post).

This means that the filter can do a decent job at removing debris and particles, ammonia (we have covered a separate article on lowering ammonia which you can find here) and nitrates, and colors and foul odors from the water.


This is an external canister filter, which means that it does not take up any space inside of the aquarium, thus saving prime real estate for plants and fish.

Yes, you will need a shelf to accommodate the filter, but it is fairly small, so this should not be a big issue.


The final thing we felt worth mentioning about the Fluval 106 is that it is fairly durable. It is made with a solid plastic outer shell that is crack and impact resistant. All in all, including the internal components, this filter is built to last.
