Fluval fx4 Review
The Fluval fx4 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 fx4 starts instantly, and does not need to be primed – less messing 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 fx4’s strengths is also its main weakness… The filtration volume is an impressive 3.7 gallons in size – filled with media helps keep your tank sparkling clear. But it also makes the filter difficult to move. An inconvenience 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 fx4 appeared to have been opened previously. I.e. it may have been a refurbished or repaired model. To ensure the integrity of your product we would recommend that you only buy it directly from Fluval via Amazon.
Overall the Fluval fx4 is an incredibly impressive filter. It is not cheap. But we do think it is worth the money to keep tanks as large as 250 gallons sparkling clean.
If you need something a little more powerful, the Fluval fx6 is a highly regarded filter than cleans aquariums up to 400 gallons in size.
