In general canister filter or external filter is used for a bigger tank since they also have more powerful pump to cycle the water inside. Among those many brands that offer fish tank filter, Fluval is one of the best options to go.

This brand has been around for quite sometime and we are sure most hobbyist are already familiar with their names as well because many people love their product which mostly reliable and coming in a competitive price compared to its rivals. We also like them for the features equipped on the unit since some are very useful and ease the work, so we can spend less effort especially on the maintenance activity.

Fluval 306 and 406 Design

As you can see from the sample picture above, both of them are coming with an identical design and if you check the whole family, they are actually also made with this same boxy design with the model name plastered at the top. However, when you place them side by side, the latter will be bigger or taller to be exact because Fluval 406 is measured at 20-inch as opposed to 18-inch Fluval 306. The latter is also slightly wider at 8-inch while the little brother is 7-inch yet the length stays the same.

Coming inside the package we have all the accessories needed to install your filter from media and pads to strainer and connectors which equally the same in either of them.

Fluval 306 and 406 Capacity and Pump

Before deciding on which model you should go with, first make sure to know how much water in your tank and if you don’t measure them beforehand, a quick way is to multiply the tank’s length with width and height then divide them to 1000 to get the size in liters but, these sizing have to be in cm first. Moving forward then we can match how big the pump needs to be for the tank by multiplying this amount to 4.

Fluval 306 and 406 are listed for up to 70 and 100 gallons respectively or up to 300 liters and 400 liters so this sizing alone can already tell us who should use the more expensive model and who should be fine with the lower pump.

This filter have a higher water circulation per hour as well at 245 gallons per hour and the other is at 306 gallons. If you are still not sure, the smaller filter is suitable for people with 45 to 70 gallons and above this number up to 100 gallons will match with the higher filter.

On the additional features side, both of them are packed with the well-known AquaStop valve which is used to connect the canister and your hose which is adored by so many people because it is extremely easy to install and use. It comes in a plastic with two connectors and a clamp to lock them in securely. The hose also attached to nuts so then owners don’t have to fear of losing them that can happen after being used for a long time.

The next attractive feature from this valve alone is the white lever which is functioning as the water flow adjustment so when we are moving this lever up or down, it will affect how strong or slow the water flow through the valve; very useful when you need to maintain or try customing the flow according to each tank’s need. We also like how easy it is to lock the head of these canister to the main body with a simple clamp on each side.
