Setup
Follow these steps to set up your Fluval FX6 filter:
- Placement: Position the filter on a flat, stable surface directly below your aquarium. The compact design (21 inches / 53 cm in height) allows it to fit under most aquarium stands.
- Media Installation: Open the filter lid and carefully place the included filter media into the stackable media baskets. The FX6 utilizes a multi-stage filtration system with precision-engineered baskets to prevent water bypass. Ensure the foam inserts are correctly positioned for mechanical pre-filtering.
- Hose Connection: Connect the intake and output hoses to the filter unit using the Aquastop Click-Fit Valves. These valves ensure a leak-free and fast assembly. Secure hoses with the provided clamps.
- Aquarium Connection: Install the versatile intake and twin output nozzles inside your aquarium. The telescopic stem of the intake helps prevent clogging, and the multi-directional output nozzles allow for customized water currents.
- Priming: The FX6 features Smart Pump Technology for self-starting. Simply add water to the canister, plug in the unit, and the Smart Pump will automatically begin the priming process, evacuating trapped air.

Maintenance
Regular maintenance is crucial for optimal filter performance and water quality:
- Media Basket Cleaning: The instant-release T-handles allow for quick and easy removal of media baskets. Clean the foam inserts and other media as needed. It is recommended to rinse mechanical media in old aquarium water to preserve beneficial bacteria.
- Water Changes: The FX6 simplifies water changes. Attach a hose to the utility valve on the filter and the Smart Pump will assist in draining water from your aquarium, eliminating the need to lift heavy buckets.
- Hose and Valve Inspection: Periodically inspect hoses, O-rings, and valves for wear and tear. Replace components as necessary to prevent leaks and maintain efficiency.
