I was thinking of replacing my fluval 305 with a fluval 406 on my 55 gallon, but the FX5 is only 20 bucks more and after doing some reading it seems like one of the better canisters out there. It really looks well built, I love the screw down lid idea and the drain plug looks handy.

I think the FX5 will be a little too powerful for my 55, but I have plans to upgrade to a 90 in the future. Does the FX5 have a flow control like the other fluvals, or is it flat out all the time?

I can get eheim and rena filstar canister filters too, but the FX5 just looks superior and I really like the fluval filters, they are more expensive though.

Chime in if you own, or have owned an FX5.

I've had one for a number of years now, and it has been a great purchase for my 90 gallon. It does have flow adjustment like the other Fluvals. I do find that I like the drain - fairly handy. The lid design is also quite solid - I've had no issues with it. I also own a couple of G6 filters as well as some smaller Eheim classics. What's nice is that even though the FX5 is pretty good sized, it's still very quiet. My smaller Eheim classics are the quietest I own, but they are moving nowhere near the same amount of water. You will need to have plenty of space for the FX5 as in my 90 stand, it takes up a good portion of the one side. Also, filled with water, you'll want to lift with your legs as it is a bit heavy. I'm quite pleased with mine. If I had another large tank, I wouldn't hesitate to get another FX5. Personally, I'd get the FX6 if I was getting another one, but that's just because I like to buy the latest - its no sleight to the FX5.

It would be a little overkill for a 55g but hey, most fish would love a current like that! I don't think that it will fit under your tank though, as it's probably too wide... I would just get the FX5 off of ebay and don't waste the money on an FX6...only difference is the FX6 comes with media, and has a pump that is a little more energy efficient. I run 2 FX5 on my 125g. Had one for 6 years, the other for just over 6 months. I also love the drain plug...I just hook up a 5/8" tube to it and drain to the shower. Soooo easy, I do 50g a week and it takes me 20 mins max. I recommend filling it with seachem Matrix for media.


125g semi planted. 2 silver angels, 14 silver tips, 16 white fin ornatus tetras, pair of Nicaraguense, pair of nototus severums, trio of firemouth cichlids. 2 FX5s, 1 1500gph circ pump, 2 48" LED lighs, and a HUGE piece of driftwood.

650g fish room. 15 30g tanks, 150g sump.

I run an FX5 on a ~41g tank, and the current is perfect imo. The stock output actually diffuses the flow quite nicely so that there is a lot of water movement, but not a jet of water that knocks anything up (sort of like a lily pipe). This is on a 24" x 18" deep x 24" high tank. The flow is adjustable via the quick connects, but the pump is noiser the more you restrict the flow. And while it's fairly quiet inside a cabinet, it doesn't compare to my 2213 for instance.
