Description
Meet the Fluval FX6—the filter serious aquarists have been waiting for. Designed to quietly handle tanks up to 400 gallons, it packs a punch with a staggering 925 GPH pump output and 563 GPH filtration flow, giving you cleaner, clearer water with less effort. What really sets the FX6 apart is its innovative Smart Pump Technology—an intelligent chip system that continuously monitors pump performance, auto-starts the system, and purges trapped air every 12 hours to maintain peak efficiency.
At the heart of its design are precision-engineered, stackable media baskets that eliminate water bypass and hold a generous 1.5 gallons of combined mechanical, chemical, and biological media. Quick-release T-handles make routine cleaning a breeze, while the whole unit stands just 21 inches tall, so it fits comfortably under most aquarium setups.
Whether you’re building a lush planted tank, a vibrant community ecosystem, or a demanding marine display, the FX6 brings reliability, power, and Intelligent design together in one compact workhorse—backed by a three-year warranty and the legacy of a brand that’s been innovating since 1975.
