Design and Dimensions
Fluval 306 Canister Filter has a tall and sturdy look. The black plastic housing features red highlights, and the combination creates a stylish and elegant appearance. Fluval 306 Canister Filter has an upright design which allows it to hold nearly 50% more media than round models of a similar size. This model has a manual priming mechanism – if you prefer automatic, take a look at Fluval G3 Review.

The media baskets are very roomy. This is a cool thing. You can fit a wide range of media into these baskets for physical, chemical, and biological filtration. The total media capacity of the canister filter is 6.6 Liters.

This canister filter features lift lock clamps that ensure a secure closure. It also has locking nuts and rim connectors that are solid and tight. The hoses are made from a durable ribbed plastic, each with a 0.5-inch internal diameter. If you prefer to use non-ribbed hoses, you can do so without needing to perform much customization. The entire system is really tight. It is very unlikely to leak.

The plastic housing feels firm and durable. It can stay upright confidently. It won’t wobble around when nudged a bit, thanks to the decent weight. It has a weight of about 15 lbs, which allows the unit to be stable while still being light and manageable enough for easy cleaning.

According to Fluval, this particular canister filter measures 10 inches wide, 7 inches deep, and 18 inches tall. Among all canister filters available in the market, Fluval 306 Canister Filter falls in the medium size category. It is still compact enough to fit under a small tank, but it also has enough power to take care of a large tank.

Suitable Aquariums
The company claims that Fluval 306 Canister Filter is suitable for freshwater and saltwater aquariums. So, this canister filter can work for a wide range of fish species. Having some extra salinity in the water will neither disrupt the performance of the unit nor alter the water quality.

According to the manufacturer, Fluval 306 Canister Filter is suitable for aquariums of up to 70 Us Gallons (300 Liters). The canister filter has a rated flow rate of 303 US Gallons per hour (1150 Liters per hour). So, it is ideal for medium and large aquariums. You can rely on these numbers if the bioload in your tank isn’t really high.

However, don’t forget to consider the amount of bioload in your tank. If you have a high amount of bioload or very messy fish, the canister filter will need to work more heavily. There will be a lot of debris and waste to filter. In this case, the canister filter is probably only suitable if your aquarium is no larger than 50 US Gallons.

Features
One special feature of Fluval 306 Canister Filter is the AquaStop valves. These valves not only secure the unit perfectly to prevent leaking, but also make it hassle-free to maintain. When you want to clean the unit, you don’t need to disconnect the hoses altogether. You only need to switch the AquaStop valves to stop the water flow. Afterwards, you can release the locks to pull out the media baskets and clean them as needed.

The AquaStop valves make the maintenance very easy and straightforward. Cleaning a canister filter often involves some water spills and splashes, but not with Fluval 306 Canister Filter.

Set-Up
If you have ever used a canister filter before, you are probably worried that this canister filter will be difficult to set-up. Strangely enough, traditional canister filters are always associated inadequate manuals and complicated installation. Unfortunately, Fluval 306 Canister Filter is no different.

After you take out all the pieces from the box, you need to assemble the unit. Put the motor in the right place and connect the hoses. Experienced users probably won’t find a real problem, but beginners may find it difficult to position the hose output in the right place in the tank.

Fluval 306 Canister Filter requires manual priming. This is perhaps the trickiest part of the set-up. Make sure that you double check all the locks before priming. Filling the filter with dechlorinated water can ease the process. Once the unit is turned on, push the priming pump a few times, and it should be good to go. If you prefer an automatic priming mechanism, consider Fluval G3 or Fluval G6 instead.

Performance

It has several media baskets in which you can put your filtration media. Fluval 306 Canister Filter is equipped with vertical twin foam pre-filters to capture large-sized debris from the start of the filtration. This significantly reduces the chance of clogging.

There adjusters that you can use to increase or decrease the flow rate as needed. It just doesn’t clog, thanks to the sophisticated design of the intake strainer.
