    I have been an Eheim fanboy for quiet some time. Lately though, I am seeing that other manufacturers have upped their game. I have a Pennplax Cascade 1200 which is well made and has great flow. This Fluval 306 is Fluval’s current 300-series canister. I haven’t owned a Fluval canister filter for the last 15 years. The quality of materials of this 306 is immediately noticeable–it is solid and well built. I have a Rena Filstar XP3 filter and the plastics for some parts are not rigid enough (especially quick-disconnect unit–had a leak issue)–not so with this canister. The flow in this filter is such that water enters the inlet, is met by coarse foam spanning the height of the canister chamber. Water then moves through 3 media baskets that you can put whatever you like in. This canister does come with fine foam,ceramic biomedia, carbon pouches–everything you need to get started. The 306 is a well-designed filter system in my book.

    The canister filter works great and has great flow. It is listed as being for up to 70gal, and I am using it at full output in a 58gal. Perfect flow. You can adjust the output down if you like by using the flow control lever on the Aquastop valve. This is the same valve that allows you to shut the water to the hoses off completely when disconnecting and servicing the unit. The canister is very quiet. The output nozzle is rather simple and can only be turned in the direction you want it to be aimed. It does not have a spray bar, nor does it have a deflector to adjust vertical spread. I have to say that the hose guides that steer the hose into the tank where you connect it to the input/output hardware is very unique. I like it better than the plastic hardware that every other canister filter uses. It has suction cups inside and outside the tank making it very stable. There is also a unique priming lever that you can use to purge the canister of air when connecting it for the first time–it took quite a few pumps but it works as advertised.

    PROS:
    +quality materials used and built solid
    +quiet operation. Have no complaints at all about operating noise.
    +Aquastop disconnect works great for reducing flow or shutting off completely to service canister
    +excellent filtration: 1 coarse sponge + 3 media baskets (in succession)
    +Hose guide brackets work really well, very stable
    +media included
    +easy and effective priming mechanism
    +powerful flow! Flow is equal to filters rated for larger tanks–I’m guessing tank size rating due to relatively small size of the unit (ie. filtering media). I for one love that it has more flow. Many I know have two canister filters per tank for water movement.
    +ribbed plastic hose is very flexible and stays kink-free. In theory it may not be optimal for flow and over time may collect more sediment more than smooth-walled tubing.

    CONS:
    -very basic output nozzle–can be turned but has no height deflector. No spraybar also if that is your thing. The output nozzle also shakes from all the flow. I bought a suction cup holder (like the included one for the intake stem) to steady it–works great!

    All-in-all, a great canister filter!!! Definitely superior to my Eheim classic 2217 and cheaper too! I would also choose this over the Rena XP2/3. I wouldn’t hesitate to recommend this canister to anyone. If any long-term issues arise, I will update this review. I am now definitely a Fluval fanboy!!!

    I uploaded a short video.

    Update 10/23/2013: This filter still works like a champ. I clean it about every other month. All seals are original. Flow remains excellent–no decrease over time. All parts look great and function grate. This is a well made filter…PERIOD. I have a classic Eheim, a Rena XP3, and PennPlax Cascade filter. The Fluval is the one I love the most, with the PennPlax second and well ahead of the other two. Highly recommended!

    Update 02/09/2016: This filter still has all the original seals and sponges. I clean it maybe once every 3 months. Works great and I still highly recommend it!

    I have 2 aquatic turtles. No filters worked even relatively decent until I got this Fluval filter. I was doing complete water changes in my 75 gallon tank every week. This filter changed all of that. It keeps the tank super crystal clear! It’s totally and completely silent, which is the best part. It aerates the water. I cannot say enough about how great this filter is! If you have fish, you’ll love it. If you have turtles, don’t waste money on any other filter, this one works best. I’ve tried them all!
