Fluval fx6 Review

The Fluval fx6 is not cheap, but it certainly delivers a punch. The FX serious is highly regarded for its power and durability, efficiently cleaning tanks and leaving them sparkling clear.

The fx6 starts instantly, and does not need to be primed. Not need to mess around trying to get the pump to start! Once running, the smart pump ensures that your pump continues to run effectively.

One of the Fluval fx6’s strengths is also its main weakness… The 5.3 gallon bucket filled with media helps keep your tank sparkling clear. But it also makes the filter difficult to move when you want to take it from it’s current location to where you want to maintain it / change filters etc.

Some users have complained that the box / packaging of the Fluval fx6 appeared to have been opened before. I.e. it may have been a refurbished or repaired model. To ensure the integrity of your product we would recommend that you only by it directly from Fluval via Amazon.

Overall the Fluval fx6 is an incredibly impressive filter. While not cheap, we do think it is worth the money to keep tanks as large as 400 gallons sparkling clean.

The Fluval fx6 is an impressive filter. If you need something a little less powerful, the Fluval fx4 is a highly regarded filter. It cleans aquariums up to 250 gallons in size.
