The Fluval 406 comes with everything you need and more, including several types of filtration media, ribbed tubing, intake tube, output nozzle, intake strainer, AquaStop valve assembly, and a quick start manual.
This is a very well-engineered filter and it’s made with quality materials. The plastics feel very heavy-duty and sturdy, especially the lid lock clamps, which can break easily on cheaper filters. This filter is clearly made to last a long time.
The only exception here is the ribbed tubing, which feels cheap and is difficult to connect to accessories like inline heaters and diffusers.
The ribbing can also be prone to catching debris and getting clogged. This is only a minor issue since you can easily go out and buy better-quality clear tubing.
Setup is not difficult if you’ve used a canister filter before, but like many other filters the confusing instructions make everything seem more complicated than it is.
Save yourself some time and watch this video for setup instructions:
Cleaning this filter is insanely easy.
The lock clamps open with one touch, and the filter is built with Hagen’s patented AquaStop valve design, which lets you clean the canister without actually disconnecting the intake and output hoses.
The AquaStop valve also includes locking hose nuts so your hoses stay securely in place, and allows you to easily adjust your flow rate.
The re-engineered self-priming system also works really well, as long as you follow the instructions.
Fluval really went above-and-beyond to make sure that operating this filter is as easy and worry-free as possible.
