Fluval 407 Aquarium Canister Filter | 150–500L (4–6 ft) | Fish Bazaar
The Fluval 407 aquarium canister filter is the most powerful model in Fluval's best-selling 07 Series, built for large and heavily-stocked fish tanks from 150 to 500 litres (roughly 4 to 6 feet), delivering around 1,450 litres per hour of 3-stage filtration. It hides in your cabinet, holds a large volume of filter media, and keeps big planted tanks, cichlid setups and goldfish tanks crystal clear with minimal maintenance — one of the strongest mid-to-large canister filters available in India.
What is the Fluval 407 Aquarium Canister Filter?
Short answer: A high-output sealed external (canister) aquarium filter for tanks of 150–500 litres that performs mechanical, biological and chemical filtration in one quiet, cabinet-hidden unit.
In detail: The 407 sits at the top of Fluval's acclaimed 07 Series. Water is drawn down, forced up through four large media baskets, and returned clean via the outlet or spray bar. With strong flow and a big media capacity, it copes with the heavy waste loads of large or messy-fish tanks while running almost silently. For example: on a 4–5 foot cichlid or goldfish tank (250–400 L), the 407 turns the volume over several times an hour, keeping the water polished and stable despite the high bioload.
Key Features
- ~1,450 LPH flow rate — powerful circulation sized for 150–500 L tanks and high bioloads.
- Large 4-basket media capacity — maximum room for mechanical, biological and chemical media, for rock-stable water chemistry.
- Quiet operation — sound-dampened motor in the cabinet, remarkably quiet for its power.
- Push-button primer — self-starts in seconds.
- Energy efficient — more flow per watt than older large canisters.
- Tidy hidden design — keeps a big tank clutter-free for aquascaping.
Benefits
Immediate: Strong, even circulation and clear water from day one across a large tank.
Short-term: As biological media matures, ammonia and nitrite stay at zero even with a heavy bioload; fish thrive and colour up.
Long-term: Stable water year-round, fewer disease outbreaks, and a durable filter with only inexpensive wear parts.
How It Works
The 407 runs water through three stages: mechanical foam traps debris; biological media grows the bacteria that convert toxic ammonia to nitrite and nitrate; and chemical media polishes the water. Its large capacity and strong flow make it ideal for heavily-stocked tanks. See how aquarium filters work.
Which Tank Size Is the Fluval 407 For?
Short answer: Tanks from 150 to 500 litres — roughly 4 to 6 foot aquariums.
| Tank length | Approx. volume | Fluval 407 suitability |
|---|---|---|
| 3.5 ft | 150–180 L | Good (consider the 307) |
| 4 ft | 200–250 L | Ideal |
| 5 ft | 350–400 L | Excellent |
| 6 ft | 500 L | Great (lightly stocked) |
| 6 ft+ | 500 L+ | Step up to the Fluval FX series |
Suitable For
- Large planted aquascapes (pairs with a spray bar and inline CO2)
- Cichlid tanks (African and American) and goldfish tanks
- Large community tanks and heavily-stocked setups
Not Suitable For
- Tanks over 500 L or pond-sized setups — step up to the Fluval FX2/FX4/FX6
- Small tanks under 150 L — the flow is too strong; choose the 207 or 307
- Nano and betta tanks — use an internal or sponge filter
Setup & Usage
Place the canister below the water line, load media in order (mechanical → biological → chemical), connect the hoses, prime with the push-button, and switch on. Use the spray bar to spread the strong flow. Allow 4–6 weeks to cycle, and stock heavy tanks gradually. See the installation guide.

Common Problems It Solves
High bioload waste: strong flow and large media capacity keep heavily-stocked tanks clean. Cloudy water in big tanks: 3-stage filtration clears debris and dissolved organics. Frequent maintenance: the large canister means cleaning every 6–8 weeks. Noise: the cabinet-hidden motor stays quiet despite the power.

Expert Recommendation
For a 4–5 foot planted, cichlid or goldfish tank, the Fluval 407 is our top high-output canister pick — it handles heavy waste loads while staying quiet and reliable. Pair it with quality bio-media such as TCWS Bio-Media or Seachem Matrix 2L, and add Purigen for show-quality clarity. Fit the spray bar to soften the strong flow.
