The AquaFX 11500 GPD Large Commercial RO System is a robust, high-capacity reverse osmosis unit specifically engineered for demanding saltwater aquarium applications. This frame-mounted system efficiently produces up to 11,500 gallons per day of purified water, crucial for maintaining pristine water quality in very large reef tanks, aquaculture operations, or public aquariums. An integrated automatic flush controller enhances membrane longevity and ensures consistent, reliable performance.

Key features of this 220V system include a high-efficiency 1-micron sediment pre-filter, a powerful frame-mounted RO booster pump, and a high-flow/high-rejection commercial RO TFC membrane housed in durable stainless steel. It is equipped with liquid-filled pressure gauges, a commercial inline TDS meter, solid aluminum mounting brackets, 20-inch canister housings, and acrylic flow meters. Essential safety and automation features include low and high-pressure switches, preventing the pump from running dry and fully automating the system. This exact system famously supplied all the water for MACNA 2018 and 2016, and top-off water for MACNA 2010, demonstrating its proven reliability and immense capacity.

This commercial-grade RO system is best suited for professional aquarists, large-scale reef facilities, or anyone requiring a substantial and continuous supply of high-purity water, far exceeding the output of typical residential units. Users must ensure the system is fed pre-treated, de-chlorinated water; AquaFX recommends a 10x54 carbon tank for optimal dechlorination. For zero ppm water, the addition of dual post 20-inch DI filters or a 10x54 DI resin tank is advised. Its robust construction and automation make it an indispensable tool for operations where water volume and purity are paramount.
