Fluval 407 Performance Canister Filter Up to 100 US Gal / 500 L

The largest canister in Fluval's Performance series, built for large aquariums up to 100 US gallons or heavily stocked tanks that outgrow smaller filtration. High flow rate and substantial media capacity make it suitable for large cichlid tanks, big planted setups, or multi-tank sump-style arrangements where filtration headroom matters more than compact size.
