Fluval 407 Performance Canister Filter

Scored on 19 verified owner verdicts, from 44 comments read across 1 community
TL;DR
Owners of the Fluval 407 are largely satisfied, especially those running it on bigger tanks (75-200 gallons/liters) where they praise its flow and capacity, and several report years of trouble-free operation with crystal clear water. It's also frequently called out as an upgrade over other canister filters, including older Fluval models, for being easier to deal with. The main recurring gripe is a persistent gurgling or hissing noise from air trapped in the intake line, which a meaningful group of owners struggle to fully resolve despite swapping hoses, sealing connections with plumber's tape, or repositioning the filter. A smaller number also flag the aqua-stop valve and top clamps as flimsy and complain that priming after maintenance can be a pain.

74% of 19 verified owners recommend the Fluval 407 Performance Canister Filter, based on real owner verdicts aggregated from Reddit, enthusiast forums, and YouTube.

What owners like
  • Handles large tanks with ease — owners run it successfully on 75-200 gallon/liter setups and praise the flow and capacity · 4 · 21%
  • Long-term reliability — owners report years of use (one 2 years, another 6 years) with no issues and crystal clear water · 3 · 16%
  • Preferred over other canister filters, including other Fluval models, and described as easier to deal with · 3 · 16%
What owners flag
  • A recurring gurgling/hissing air-in-line noise that's hard to permanently fix — owners cycle through hose swaps, plumber's tape, and repositioning the unit with mixed results · 7 · 37%
Who it's for
A great fit if
  • Owners of 75-125 gallon tanks needing strong, reliable long-term flow
  • Fishkeepers who want a quiet canister that runs untouched for years
  • Anyone upgrading from sponge filters who wants more media/customization options
  • Owners willing to do occasional foam-only maintenance rather than full teardowns
Look elsewhere if
  • Owners who prioritize easy restarts/priming, since restart and airlock issues recur
  • Anyone put off by build quality gripes like the aqua-stop valve and top clamps
  • Buyers wanting a plug-and-play kit, since spray bar isn't included

It is ugly and the inlet feels way too big.

Did own a fluval407, real quiet filter with lots of potential.

Reddit▼ don’t recommend

I do not recommend the Fluval simply due to their aqua-stop valve being poorly made and their clamps that hold the top down are not ideal either.

Reddit— neutral

mine is also a right pain to restart and the priming handle doesn't seem to do much.

Extra info...They are in a 75gal fully cycled etc. using a Fluval407 with a spray bar facing the back of the tank to minimize flow and they also have two air stones. I'm currently cycling out the black sand so don't come at me please. I don't want to take it all out at once and have a cycle crash.

It's a Fluval 407 Performance Canister Filter we bought it at Pet Smart.

And #2 it takes up space in the filter where instead you could have more bioballs and some foam etc which is always great to have more of. My fluval407 is filled with nothing but sponges and bioballs and the likes... I'm only 3 yrs in, but from what I've read, that is how most successful aquarist do it.

Fluval 407 Performance Canister Filter. Have not added any substrate at the bottom since upgraded to the bigger tank. Only the turtle, filter and her platform.

Redditⓘ good to know

And this is the canister filter I use, I have a 75 gallon tank so depending on your tank size you could get the smaller version https://www.petsmart.com/fish/filters-and-pumps/filters/fluval-407-performance-canister-filter-5290152.html

The whole thing was valued over $825. All I needed to do was get a high powered water heater ($50), get new media for the filter (about $70 total), added some decorations (about $100 total) as I already had my turtle topper, and the whole upgrade was about $370.

I have both the FX4 and 407. My personal opinion is that the FX4 works best in 6ft long tanks, unless you need strong water flow. It's very powerful. The 407 is suitable for a tank that size.

Redditⓘ good to know

really easy. considering you have a sink or bathtub available. the hoses have a quick release lever so the water cuts off instantly when removing.

I am having this issue currently. Just read your post. I think it’s from having slag in the hose. I have mine filter up on table I built and it makes slag in the hoses . If I hold the filter off and below the table it stops.

Redditⓘ good to know

If flow is strong let it ride. Won’t hurt but some filter bags dissolve over time. At least the fluval 407 canister filtration bag have.

Redditⓘ good to know

I never figured out personally what was going on, but I moved a few months ago and when I set up the filter at my new place it stopped doing this. No idea what changed but might be worth moving the placement around or something, I dunno, lol.

Redditⓘ good to know

I have Fluval 407 too, just clean the foam to remove the big debris. When you siphon clean the gravel, drain it in bucket, then open your canister, pull out the foam cartridge only, take out the foam and wash it in the bucket with the aquarium water.

I have two sponge filters and the Fluval 407 canister, so ordering purigen now! Thank you :)

Redditⓘ good to know

Sounds like air/air bubbles in the canister. You may need to open it up and add more water or turn it off and reprime. You shouldn't have that trickling water sound. If you just have that offgasing noise, it can be caused by air bubbles and will often dissipate over time.

Redditⓘ good to know

I agree, I run fluval 407s on most of the tanks, they range from 20g to 75g, and for the larger ones, I have FX6's. Dont get me wrong though, ive used sponges and got very good results throughout my fish keeping journey. Personally, I really like the options a canister filter gives you.

I just got a 75 with a fluval 407. Spray bar is not included.
