Fluval Fx6 and Fluval FX4 Review and Specifications
Fluval FX6 Review
For our Fluval FX6 review, we installed Fluval FX6 External Canister Filter to a 350 US Gallon tank. The tank water was cloudy with added impurities and bio-waste to test the actual filtration efficiency of the filter. The filter did an exceptional job in cleaning the impurities and other waste making the water crystal clear.
Though with the added impurities and water being very cloudy the filtration time was more than normal. But later in the week filtration was carried out normally. As Figure 1 indicated, the filter has 6 filtration stages to ensure optimal filtration of your tank. Read the specification to know what’s included in the box.

So, how is Fluval Fx6 and FX4 different from the rest in Terms of Maintenance?
The flow rate of the filter is very good and maintained till the end of the maintenance cycle. Since the water passes through the outer foam first, larger debris is eliminated maintaining the flow rate and preventing clogging of inner media.
The filter comes with a lot of handy functions that makes the maintenance hassle free just like setting up the filter. Many times we tend to forget the maintenance schedule, so the filter comes with the Indicator Dials so you never miss the next maintenance and water change date.
And there’s more…
Additionally the purge valve at the bottom of the filter that could assist you in avoiding a mess while carrying out maintenance.
The Purge Valve
The Fluval FX series Filter comes with a unique feature of ‘Purge valve‘ also called as the ‘Utility valve‘ which comes in handy to avoid a mess.
It is a multi-purpose valve at the bottom of the Filter which could be used as a direct input or output. The Gravel Vac cleaning uses utility valve for the input, whereas you could empty the tank or refill it using the utility valve.
Helps you empty the canister before moving it for maintenance.
You could do empty/fill your tank using the utility valve, avoiding the mess caused by manual siphoning.
- Turn off the input and the output AquaStop valve
- Attach a hose to utility valve with an output to the bucket or to drain.
- Turn on the input aqua-stop valve and the utility valve.
And similarly, you could fill in the tank using the. We found this approach quite convenient since there was hardly any water spillage and mess. And we are sure you would love it too.
And there’s even more…
The Gravel Vac(Included in the newer models) is a unique add-on feature which is very useful for cleaning the parts of the Aquarium which are not reachable during normal filtration. Using an extended suction pipe, prefiltered and then let in through the utility valve. The water sucked in then goes through the filter media in the media baskets and finally clean water is back through the Filter outlets.
This a feature that you would find very helpful in maintaining the overall health of the Aquarium by eliminating plant debris, excess food, fish waste and much more. The fine filter pad is capable of cleaning even the finest of particle leaving you tank sparkling clean. This is a unique feature among the filters in this range.
