newly-released Fluval fx4 NIB
The Fluval FX4 Canister Filter features patented Smart Pump performance-optimizing technology, intricate multi-stage filtration, a built-in powered water change system and basket-in-basket tray design offering greater media capacity. It is the ideal choice for aquariums up to 250 US Gal (1000 L). Smart Pump Technology is critical in evacuating any air that may build up in the system. Once every 12 hours, the filter will pause and allow any trapped air to escape, thereby maintaining maximum filtration efficiency. Just add water and Smart Pump will prime in seconds. The FX4 features a multi-functional Utility Valve drain at its base, making it possible to empty the canister and perform seamless water changes by draining and refilling water directly from it. Convenient lid-mounted hosing clips offers clean storage when not in use - no need to reconnect for subsequent use. The lift-out stack of media baskets is at the heart of Fluval multi-stage filtration. Theselarge capacity
