The AquaFX 7500 GPD Large Commercial RO System is a robust, high-capacity reverse osmosis unit engineered to deliver immense volumes of purified water for demanding saltwater aquarium and aquaculture applications. Capable of producing up to 7,500 gallons per day, this system ensures a consistent supply of ultra-pure water, which is essential for maintaining stable parameters and the health of sensitive aquatic life in large-scale setups, from public aquariums to commercial facilities requiring significant daily water production.

This 220V system boasts a comprehensive suite of features, including a high-efficiency 1-micron sediment pre-filter, a frame-mounted RO booster pump, and a high-flow/high-rejection commercial RO TFC membrane for superior water purification. It is equipped with a liquid-filled pressure gauge, a commercial inline TDS meter for real-time monitoring, and durable 20-inch canister housings. Constructed with a solid aluminum mounting bracket and stainless steel membrane housing, the system also integrates acrylic flow meters, a low pressure switch to prevent pump damage from running dry, and a high pressure switch for fully automated operation. This exact system notably provided all water for MACNA 2018 and top-off water for MACNA 2016 and 2010.

This commercial-grade RO system is ideally suited for facilities that require production exceeding 1000 gallons per day, such as large public aquariums, commercial fish farms, and very extensive home reef systems that demand industrial reliability and output. Users must ensure feed water is properly de-chlorinated, with AquaFX recommending a 10x54 carbon tank for pre-treatment. For achieving zero parts per million (PPM) water, the system can be augmented with dual post 20-inch DI filters or a 10x54 tank filled with DI resin, providing ultimate purity for the most sensitive marine environments.
