In-depth Comparison Between Fluval 307 and 407

When comparing the Fluval 307 with the 407, there is so much you need to know. This section will give you a detailed overview of everything. 


The size of your fish tank is one of the first considerations you’ll make when choosing an aquarium. Different fish require various tank sizes. Most cannot flourish in tanks too small for their species.

Once you’ve chosen the size of your tank, you’ll have to select a filter capable of handling it. The capacity of a filter is the largest aquarium it can adequately filter.

The Fluval 307 has a capacity of 40-70 Gal or 90-330 L. The Fluval 407, on the other hand, has a capacity of 50-100 Gal or 150-500 L.

A filter that is too tiny will not be able to manage the waste generated by the fish. A filter that is too big just wastes energy.

Winner: There is no particular winner for this round. The capacity you need depends on your aquarium’s size. So any of the two can be good for you. 

Pump Performance

Canister’s pump performance is a little tricky to understand. It is the volume of water the pump section of the filter can move. It is specific to when entirely unconstrained by filter material. The pump output is measured in gallons per hour (Gal/h) or liters per hour (L/h).

The Fluval 307 has a pump performance of 303 US Gal/h or 1150 L/h. The Fluval 407, on the other hand, has a pump performance of 383 US Gal/h or 1450 L/h.

Winner: The winner of this section is the Fluval 407. It is because the pump performance of that canister is better than that of the 307. 

Filter Circulation

Filter circulation is also measured in gallons per hour or liters per hour. It relates to the volume of water that the filter can move when the proper filter material is used.

One of the most crucial factors to consider when purchasing a new filter is filter circulation. It’s important to understand your filter’s pump performance. Because you will almost certainly never have to operate your filter without filter media.

This is the reason filter circulation is so much more important than pump performance. So what is the most reliable indicator of how well your filter will operate in your home aquarium? Well, it is the filter circulation rate.

The Fluval 307 has a filter circulation rate of 206 US Gal/h or 780 L/h. The Fluval 407’s rate is 245 US Gal/h or 930 L/h.

Winner: The winner of this round is the Fluval 407. This is because it has a higher filter circulation rate. And we already mentioned how important this aspect is.


Canister filters are often housed beneath an aquarium. They aren’t commonly tied to the aquarium due to their size and strength.

Some of you just have a little amount of room beneath your fish tank. It’s critical to know the size of your new canister filter. Or else you might get something that will not fit in the spot.

The Fluval 307 measures 9.5 x 7 x 16.5″ or 24 x 18 x 42 cm. On the other hand, the Fluval 407 is 9.5 x 7 x 19.3″ or 24 x 18 x 49 cm.

The only difference in dimension is in the height of the canister filters. So both of the canister filters will take up the same amount of space in the ground. But the Fluval 407 is taller and will require more headroom. 

Winner: The winner of this round is the Fluval 307. It is because of its lower height. So it will be able to fit in more compact spaces, where the 407 might not fit.  

Power Consumption

Your canister filter will be running 24/7. So cannot run your aquarium without the filter. So power consumption of such items that run for prolonged periods is a huge factor.

A canister filter with a higher power draw will consume more electricity. That in turn will rack up your electricity bill. Higher power consumption may lead to more heating as well.

The Fluval 407 is bigger and more capable than the Fluval 307. So naturally, the 407 requires more power.

The Fluval 407 requires 23 watts. So How many watts is Fluval 307? The 307 only needs 16 watts.

So you can run both of the canister filters for the same amount of time. But the Fluval 307 will require significantly less energy than the Fluval 407. So running the Fluval 307 is cheaper as well.

Winner: The Fluval 307 wins this round due to having significantly less power draw. But remember that the higher power draw of the Fluval 407 is because of its higher performance. 


Now this section is about what you get right out of the box. Of course, you will get the canister filters themselves. But what else do you get?

Both of the canister filters come out of the box with months worth of supplies.  Both will come with 6-months worth of supplies

Here is what you can expect to see while unboxing the Fluval 307: 

  • 12 x Carbon 100 g 
  • 6 x Quick Clear Polishing Pads 
  • 12 x Phosphate Remover Pad

Now the Fluval 407 comes with two extra bags of charcoal or carbon.

Winner: The winner of this round is the Fluval 407 because it comes with more right out of the box.  


All electronics have the risk of malfunctioning. So a warranty helps ease the mind and gives you reassurance. 

Both of the canister filters in the discussion are from the same company, Fluval. They are just different products in the same product series.

So you can expect to get the same warranty and service from both of the canister filters. Both of them come with a base warranty of 3 years.

This warranty will repair or replace non-replaceable and non-serviceable items. The warranty excludes wear and tear components such as the impeller assembly and motor seal ring. The warranty does not cover normal wear and tear or items that have not been properly or appropriately maintained.

Winner: This round is a draw. Both canister filters have the same warranty policies. 


Price is a significant factor when it comes to making any purchase decision. So let us see which of the two canister filters is more budget-friendly.

The price of the Fluval 307 gph is around $185. While the Fluval 407 costs around $220.

So just based on the price tag, the Fluval 307 is quite a bit cheaper. The cost of operating the 307 is also less as it has a lower power consumption.

But the higher price tag of the Fluval 407 might be justified. The 407 has more power and is more capable.

Winner: purely based on the price, the winner of this round is the Fluval 307
