If you’re searching for the Fluval 106, 206 or 306, the short answer is that Fluval has discontinued the whole 06 series (106, 206, 306 and 406) in favour of the 07 series: 107, 207, 307 and 407. Each old size maps directly onto its replacement (106→107, 206→207, 306→307, 406→407), and the good news is the sizing carries over closely. What’s different is internal: a redesigned media basket, a quieter pump, and a few small efficiency gains. This guide compares the current 07-series lineup and explains exactly what carried over from the model you were originally looking for.
What stayed the same, what changed
Flow and wattage are unchanged in every size: 550, 780, 1,150 and 1,450 L/h, and 10, 10, 15 and 20 W at 230 to 240 V. The tank-size ratings were raised slightly. Fluval rated the 106 for up to 100 litres, the 206 up to 200, the 306 up to 300 and the 406 up to 400, against 40 to 130, 60 to 220, 90 to 330 and 150 to 500 litres for the 107 to 407.
What changed:
- EZ-Lift media basket: a center-handle design that lets you pull the whole media stack out with one finger, without draining the canister first. The old 06 series used a simpler basket design without this.
- Bio-Foam Max sponge: a rippled-surface foam with roughly 30% more surface area for trapping waste and debris than the previous flat-surface foam, reducing how fast the mechanical stage clogs.
- Quieter pump (eTEC): Fluval markets the 07 series as noticeably quieter running than the 06 generation at the same flow rate, though this is a manufacturer claim rather than something independently measured here.

Tank size, flow and wattage are the figures Fluval publishes for the 07 series, as printed on our product pages. Wattage is for 230 to 240 V at 50 Hz, the mains supply in India.

Which size fits your tank
107 suits a nano-to-small tank up to about 130 litres (the 106 was rated to 100 litres), with the refined internals above.
207 covers the common mid-size community tank, 60-220 litres. It’s the size most people mean when they say “Fluval canister” for a standard setup.
307 is the step up for anything heavily stocked or a larger community tank, 90-330 litres. As with any canister filter, where your tank falls between two sizes, size up rather than down: an oversized filter runs a lower proportion of its capacity and goes longer between services, while an undersized one has no fix short of replacing it.
407 is the largest in the current lineup, rated to 500 litres, and the one to reach for on a large or heavily-stocked tank where even a 307 would be running near its limit.
Matching a size to your tank dimensions
Volumes here are gross (length times width times height). Take off about 10 percent for glass, substrate and decor.
| Tank (L x W x H) | Gross volume | Fluval 07 series size |
|---|---|---|
| 2 ft x 1 ft x 1 ft | about 57 L | 107 (40 to 130 L) |
| 2 ft x 1.5 ft x 1.5 ft | about 127 L | 107 at the top of its range, or 207 (60 to 220 L) |
| 3 ft x 1.5 ft x 1.5 ft | about 191 L | 207, or 307 (90 to 330 L) |
| 4 ft x 1.5 ft x 1.5 ft | about 255 L | 307 |
| 4 ft x 2 ft x 2 ft | about 453 L | 407 (150 to 500 L) |
If you already own a 106, 206 or 306
Your filter isn’t obsolete. Fluval’s own parts catalogue and IndieFur’s stocked spares both continue to support the 06 generation, and several parts are shared across both generations outright:
- Motor head gasket, 106/206/107/207: listed as one part across both generations, the seal most likely to need replacing over years of use.
- Magnetic impeller, 106/206: the part that wears fastest from constant rotation; a worn impeller is a common cause of reduced flow or unusual noise.
- Ribbed hosing, 106/206: worth replacing proactively if hosing has hardened or cracked rather than waiting for a leak.
- 107/207 Media Value Pack: bundled mechanical, biological and chemical media; check compatibility with your specific canister basket before ordering if you’re running the older 06-series basket design. Currently out of stock at IndieFur; check back, or ask about restocking.
The full parts range (including 306/406-specific gaskets, impellers and hosing) is in the Fluval Equipment Guide.
Looking after your 07 series canister
Fluval’s 07 series chart, as quoted on our spare-part pages, sets the routine for the 07 series and for the shared 06 parts.
- Motor head gasket: check and clean it every three months and replace it yearly. Fluval says it deteriorates over time and can leak. The 106/206/107/207 gasket and the 307/407 gasket are the parts.
- Ribbed hosing: check and clean it monthly, because the blockage forms on the inside where you cannot see it. The 106/206/107/207 hosing and the 306/406/307/407 hosing are different bores and do not swap.
- Lubricant: use silicone-based lubricant only on seals and O-rings. Fluval says petroleum jelly and vegetable or animal products must not be used.
- Before you open it: turn the IN and OUT valves to the closed (horizontal) position, unplug the pump, then disconnect.
Fluval gives the 07 series a 3-year warranty, extended by 2 years if you register the product. Allow clear cabinet height for the canister plus room to lift the motor head off. Our canister filter cleaning guide covers the media routine.
If you’re buying new
IndieFur sells the four complete 07 series canisters: the Fluval 107, 207, 307 and 407. The Fluval Equipment Guide covers the spares, media and heaters that go with them. If you are choosing between brands rather than committed to Fluval, our EHEIM Canister Filters Compared guide covers the EHEIM range.
FAQ
Is the 07 series better, or just a rename? Flow rate and wattage are identical to the equivalent 06-series model, and the tank-size rating is slightly higher. The media basket, foam media and pump noise are genuinely improved. If you already own a working 06-series unit, there’s no filtration-performance reason to replace it.
Will my old 106/206/306 media basket fit a 107/207/307 canister body, or vice versa? Not confirmed to be interchangeable: the EZ-Lift basket is a redesign specific to the 07 series. Check the specific listing before assuming a basket or media pack swaps across generations; the shared parts (gasket, impeller, shaft) are the ones explicitly cross-listed, not the basket itself.
Which 07 series size replaces my 106, 206 or 306? The 107 replaces the 106, the 207 the 206, the 307 the 306, and the 407 the 406. The 06 series was sold as 106, 206, 306 and 406.
Can I use 06 series media in a 07 canister? Our Fluval 107 product page states that 07 and 06 series media are interchangeable in it. That covers the media. The EZ-Lift basket is a 07 series redesign, so check a basket listing before you assume it swaps.
