## Summary description

Replacement shower-style diffuser for Fluval FX4 and FX6 external canister filters. Adjustable length 64–140 cm to suit different aquarium setups; designed to spread return water flow evenly and reduce substrate disturbance. Compatible with Fluval FX series return lines; ideal for hobbyists seeking quieter, gentler circulation and improved water distribution in planted or community tanks.

## Long description

The Fluval Shower Diffuser for FX4/FX6 Canister Filters is a replacement shower-style return fitting designed to improve return flow distribution and reduce substrate disturbance in planted and community aquariums. With an adjustable length from 64 to 140 cm, the diffuser fits a range of aquarium sizes and return line layouts. It connects to Fluval FX-series return tubing and provides a gentler, more even flow compared with a single-point outlet, helping to minimize strong jets and localized currents.
Advantages
This adjustable shower diffuser spreads return water across multiple outlets to produce an even, low-velocity flow that reduces stirring of substrate and prevents strong localized currents. Its telescoping length allows precise placement of the diffuser along the back or side of the tank to match aquarium dimensions. Designed for compatibility with Fluval FX series return plumbing, the diffuser is simple to install and can contribute to quieter operation and improved surface circulation for more consistent filtration performance.
Suitable for
 Planted aquariums where gentle, distributed flow protects delicate plants and substrates
 Community tanks with mixed species that prefer low to moderate water movement
 Aquariums where reduced substrate disturbance is needed for clarity and decor stability
 Setups requiring adaptable return fitting lengths to match tank size or layout
Key specifications
 Adjustable length: 64–140 cm
 Shower-style diffuser design for distributed outflow
 Compatible with Fluval FX-series return tubing
 Material: durable plastic suitable for freshwater and typical aquarium use
 Installation: inline connection to return line, no additional tools required for basic fit
How to use
Install the diffuser by connecting it inline to the Fluval FX series return tubing according to the aquarium layout and reach needed. Extend or retract the diffuser to the desired length (64–140 cm) so that the outlets are positioned along the back or side of the tank where even flow is desired. Ensure secure tubing connections and check for any leaks after restarting the filter. Adjust angle and position to fine-tune flow distribution and to avoid directing strong jets at plants or decorations.
Usage recommendations
Position the diffuser outlets above the mid-height of the aquarium for improved surface circulation without creating strong bottom currents. Periodically inspect and clean the diffuser openings to prevent clogging from debris or biofilm. When using in heavily planted tanks, start with a shorter exposed length and increase gradually to achieve the desired flow while monitoring plant response.
