For people with massive aquariums (50 gallons or above), we present the Fluval 306 review. This filtration system features expert design and efficient performance.

Let’s dive in and look into the detailed analysis.

Fluval 306 External Canister Filter

Before You Buy a Filtration System

Taking proper care of your aquarium tank can sometimes seem challenging, especially if your filtration system lacks some essential qualities. Although Fluval 306 can help you in keeping the water in your tank neat, however, like every product, it has some cons too.

·      Price

Forget about being cheap; the external filter is not even affordable for some people. It can way out your league if you do not have a reasonable budget. Well, there is no denying that the item has exceptional features; however, one must have the money to afford it before they can use it.


So, you must consider your budget before purchasing the device. It is not worth it if it ends up breaking your bank.

·      Installation Process

Setting up the product is one most complicated tasks you will ever face if you are not a professional or an expert in this field. Although you will receive a user manual yet installing the item requires more than the help of the guide.

Assembling the items of the package is not a difficult task; however, positioning the hose output in a suitable spot is a totally different thing. Therefore, you should either watch some guide videos from YouTube or use the help of a professional.

·      Cleaning

As a canister filter, the 306 takes up a moderate amount of time for the cleaning process. You cannot wash the entire thing in one go. So, you will have to unplug the filter, disconnect the tubing, and remove all the parts accordingly.

Then you will need to clean the media and all the other parts individually. Besides, the impeller requires more attention than other components because it is the life source of your filter.

·      Capacity

One of the most significant aspects of Fluval 306 is its capability to handle small, medium, and large aquariums. You can use the product for tanks of 12 gallons or 70 gallons.

Usually, large aquariums require more than one filtration media. However, it is not the same case for Fluval 306 as it can work with large tanks efficiently. It means you will only need to buy one product even if your tank is a huge one.

·      Lift Lock Clamps and Aqua-Stop Valves

These features help users to clean and maintain the product without much nuisance. The lift lock clamps enable you to lock the motor in a particular position.

On the other hand, the Aqua-Stop valves allow you to stop the flow of the water without manually disconnecting the hoses. Moreover, the valves reduce clutters and leak that may occur inside the tank.

·      Size and Design

Fluval 306 comes with a unique design to dampen the production of sound. It reduces 8-15% of the sound produced while the item is operational. Moreover, the product has a screen with dual-layer foam.

Unlike the other models of Fluval filtration media, the 306 comes in a medium-sized pack. It almost has a similar height to the palm of a hand. Therefore, it is easy to place in a tank, whether it is small or big.

Usually, canister filters are enormous due to their powerful flow rate and exceptional filtering capacity. However, Fluval 306 offers the same results with a medium-size design, which is in one word ‘extraordinary.’
