Fluval vs Aqueon Filter: Canister and HOB Compared

The short answer

Neither brand wins on every point, so compare one filter type at a time. Fluval’s 07 canisters carry a 3-year warranty, Aqueon’s QuietFlow canisters 12 months. Modest Fish, scoring installation, priming, maintenance and noise, ranked the Fluval 407 second, the Eheim Classic third and the Aqueon QuietFlow fifth of seven, and called the Aqueon its tight-budget choice.

Canister filters: the makers’ own figures

Fluval publishes two flow figures for the 307: pump performance, and a lower “filter circulation” figure that its manual says was measured “with intake and output hoses of the same length”. Aqueon’s manual gives 200 gph with no stated conditions, so it is not known whether that is pump output or flow with media. Eheim’s figures come from its European page, at 50 Hz; the US-gallon conversions are ours.

Filter	Rating, flow and power (maker)	Media volume; warranty (maker)
Fluval 307	40-70 US gal; pump 303 US gal/h, circulation 206 US gal/h; 16 W at 120 V	Basket volume 3.1 L; 3 years, impeller assembly and motor seal ring excluded
Aqueon QuietFlow 200G	Up to 55 gal; 200 gph; 0.25 A at 120 V (no watts given)	Media volume not in its manual; 12 months, limited
Eheim Classic 250	Up to approx. 250 L (about 66 US gal); approx. 440 L/h (about 116 US gal/h) and 8 W at 50 Hz	Filter volume 3 l; 2 years in the model table

What one side-by-side test measured

Modest Fish, a fishkeeping review site that earns Amazon commissions and says “We purchase every product we review with our own money”, timed seven canisters in a roundup dated April 14, 2026. It ran each filter “with its included media”, using “nice clean media”, diverted the outflow “into a 2 gallon (7.5 liter) container”, timed it three times and averaged, and read noise “with a handheld decibel meter multiple times”. Its overall ranking adds 1-5 scores for installation, priming and maintenance to a noise rank; the timed flow is not in that list.

Filter tested (rank of 7)	Measured flow	Noise
Fluval 407 (#2)	240.64 GPH	51.9 dB
Eheim Classic, model not named (#3)	105.11 GPH	51.0 dB
Aqueon QuietFlow, size not named (#5)	157.96 GPH	54.9 dB

The three are not the same size: the Fluval was the 407, which Fluval rates for 50-100 US gal. Modest Fish’s separate Aqueon review, with the same 54.9 dB reading, lists 200 GPH, and its Eheim review, with the same 105.11 GPH, quotes a rating of “up to 92 gallon (350 liter)”, which matches Eheim’s Classic 350. So the table compares three filters, not three brands. Modest Fish says “the actual GPH of each filter turned out to be much lower than the rating listed on the box.”

Its #1 was the larger Fluval FX6, and it wrote: “As usual, Fluval made the best showing.” On a tight budget, “the Aqueon Quietflow would probably be my first choice”, and “the Eheim is a great choice for smaller tanks”.

Priming and running costs

Priming. Fluval’s 07 manual says to “Pump the instant-prime handle”. Aqueon’s says, with a spray bar or water director, to “Slowly pour water into Canister Filter through hole in the center of the Fill Funnel”; with the polishing unit attached, to “slowly pour water directly into the Housing”. Re-priming after maintenance is not needed if you “close the Quick Disconnect Valves before disconnecting the canister for maintenance”. Eheim’s 2213 manual gives three ways, including “by sucking the hose on the pressure side”.
Running costs. Fluval’s 07 chart replaces carbon monthly. Aqueon calls for a “carbon change every 30 days”, and its polishing unit takes Large Aqueon cartridges: “replace monthly”. Eheim’s 2213 manual says the starter carbon pad “should be removed” after about two weeks. Our guide to carbon in aquarium filters covers its use.

Hang-on-back filters: AquaClear vs Aqueon QuietFlow

Point	AquaClear (Fluval)	Aqueon PRO QuietFlow
Starting	Fill the case; “Allow 30-45 seconds for priming”	“Internal auto-start pump requires no priming”
Media	Foam, carbon and BIOMAX inserts; carbon replaced monthly	Carbon cartridge plus Bio-Holster; cartridges “every 4 to 6 weeks”
Warranty	3 years (AC20/30/50/70 manual); 2 more if registered within 30 days (“LIMITED TIME OFFER!”)	Limited lifetime (“Quietflow Power Filters” row; PRO not named)

Aqueon’s PRO QuietFlow page lists sizes 10, 20, 30, 50 and 75 but no flow or tank rating, so flow is not compared here. AquaClear’s chart replaces the foam every 2 months and BIOMAX every 3, and its manual says to “adjust flow control to desired output”. Aqueon’s cartridge page also says “approximately every 4 weeks”. Its warranty table gives QuietFlow LED Power Filters 1 year, not lifetime, so check which model the box names.

In a 2014 WaFishBox forum thread on the older QuietFlow 55/75 (not the PRO in the table) versus the AquaClear 110, one owner wrote “The Aqueon hobs are self-priming and quieter, as the name suggests”, but “the media isn’t anywhere near as DIY-friendly as the aquaclears”. An AquaClear owner there wrote “with these filters maintenance is minimal and so are failures”, but “I have had to replace some impellers (on the 50’s).”

What canister owners report

Fluval. A FishLore owner who bought a 407 in June 2021 found it “extremely quiet”, but “the actual media capacity is much smaller” than the owner’s Marineland Magniflow 360. In January 2025, an r/aquarium 407 owner wrote “priming initially was iffy but it runs great and quieter than I expected”.
Aqueon. A Monster Fish Keepers member running a QuietFlow (size not stated) on a 135-gallon tank for 2-3 years wrote in June 2024 that “it’s been reliable and keeps my tank super clear”, though it is “Not my fav”. A June 2021 FishLore Marineland owner passed on second-hand that “a lot of people complained that the Aqueon was hard to clean”, wondering whether they were new to canisters.
Eheim. In a February 2020 FishLore thread, a 2213 owner wrote “It really is dead silent.”; a 2215 owner wrote “My Eheim has never been silent, but it is hardly loud.”
Both. In a 2017 r/Aquariums thread about a 30 and a 90 gallon tank, one owner wrote: “The main difference is flow vs media capacity, fluval being strong in flow but eheim with higher media capacity.”

Which one fits your tank

Aqueon says “A hardworking filter should have a flow rate at least four times the volume of the tank per hour”. Our arithmetic with Aqueon’s rule (flow divided by four; the rule is Aqueon’s, not Fluval’s or Eheim’s): Fluval 307 circulation 206 gives about 51 gal (pump 303, about 76); Aqueon 200 gph gives 50 gal; Eheim Classic 250 pump at about 116 gph (50 Hz) gives about 29 gal. The makers rate them for 70, 55 and about 66 gal.

Choose a Fluval 07 canister if you want a 3-year written warranty (Eheim’s model table lists 2 years for the Classic, while its site banner says “up to 36 months”; US terms not checked), an instant-prime handle and a published circulation figure.
Choose an Aqueon QuietFlow canister if price leads: Modest Fish called it “one of the most economical filters of the bunch”. With its polishing unit, budget for monthly cartridges; the warranty is 12 months.
Choose an Eheim Classic if you want a simple canister you fill with pads or loose media; Modest Fish recommended its Classic for “30-40 gallon” tanks.
For a hang-on-back, choose AquaClear for flow control and separate inserts, or Aqueon’s PRO QuietFlow for a self-starting pump and drop-in cartridges.

Frequently Asked Questions

Q. What is the best brand for aquarium filters?

The sources disagree. In a 2025 r/aquarium thread where Fluval was named most often, one owner wrote “Fluval is the best on the market.” and another “I’m not actually convinced there’s a big difference between the major filters.”

Q. Is Fluval better than Aqueon?

No source we read ranks the brands across all filter types; Modest Fish’s canister ranks are above.

Q. Do Fluval and Aqueon filters work in saltwater?

Fluval’s 07 manual says its canisters “may be used with fresh or salt water”, Aqueon says both its QuietFlow canister and PRO QuietFlow suit freshwater and saltwater, and Eheim marks the Classic “Yes” for sea water. Our marine canister filter roundup covers saltwater models.

Q. Do these warranties need a receipt or registration?

Aqueon’s claims are “verified with a copy of the original dated purchase receipt”. Fluval’s 07 manual: “WARRANTY IS ONLY VALID WITH PROOF OF PURCHASE FROM AN AUTHORIZED FLUVAL DEALER.” Fluval’s AquaClear manual: “Register this product online within 30 days of purchase and Fluval will extend your current warranty at no charge.”
