Who Should Get the Fluval External Filter 106

Is the Fluval 106 the right match for your tank? The first thing that you should check is the size of your tank. This item is rated for aquariums that can hold up to 25 US gal. If yours is smaller, it can be a good primary filter. If it’s bigger, you can still opt for this item but in combination with another one so you can get the right amount of water flow your tank requires.

Another consideration is your preference. It’s a highly customizable filter, so if you’re planning on trying out mixing and matching various combinations of media, this item can be a great choice for you. Its flow rate control will also give you the freedom to set the water flow according to your specifications so if you want to have control in that area as well, the Fluval 106 can be a great pick for you.

Feature Overview

One of the things that make the Fluval 106 a popular pick is the fact that it’s feature-packed. What are these functionalities that might just win you over, you ask? Here are a few of the key ones that should peak your interest:

25-Gallon Capacity, 145 GPH

Ensuring that this filter can move a lot of water within a short span of time is the ratio between its capacity and GPH. As it’s only recommended for tanks up to 25 gallons, having a 145 GPH makes it more than capable of quick water turn over. As a result, you can be guaranteed that it can keep the water in your tank in great shape all the time.

Flow Control

While a quick water turn over ensures effective cleaning, it’s not suitable for all kinds of tanks. If you have changing needs, however, the fact that the Fluval 106 has a flow control valve makes it more versatile and reliable. With just a simple turn of the valve, you can already change the water flow inside your tank.

Aquastop Valve

Promising quick and mess-free maintenance is the Aquastop feature that comes with the Fluval 106. This valve will prevent leakages and messes when you have to disconnect the filter from the tank.

Clog-Proof Intake Strainer

With how powerful the water flow of the Fluval 106, there’s a chance that it can suck small items inside your tank. The intake strainer works to keep your filter’s waterways from being clogged up by having an intake tube equipped to keep debris out.

Lift-Lock Clamps

Like lots of other canister filters, the motor and the filter media container of the Fluval 106 can be completely taken apart. To keep the motor and filter media in place, however, the lid seals the canister nicely. To add an extra layer of security, this canister filter is also equipped with lift-lock clamps to keep the two parts together.

Instant Prime

Making this canister filter extra convenient is its instant prime switch. You just need to press on it twice and the Fluval 106 will automatically start priming itself.
