The AquaFX Blue Fin PRO is a high-capacity, 7-stage reverse osmosis deionization system designed to produce up to 500 gallons of ultra-pure water per day. This light-commercial unit bridges the gap between smaller residential systems and full-scale commercial setups, delivering a massive volume of purified water suitable for the most demanding saltwater aquarium applications. It efficiently removes contaminants, chlorine, heavy metals, and dissolved solids, providing a perfect foundation for mixing saltwater or for topping off your aquarium.

This system is engineered for performance, featuring a large 500 GPD RO membrane that operates effectively at standard household water pressure. Key features include an integrated triple-TDS meter with a backlit display for monitoring water quality at multiple points, an automatic shut-off kit to conserve water, and an adjustable flow restrictor for fine-tuning performance. The Blue Fin PRO also utilizes oversized 10x4 pre-filter and deionization cartridges, which provide longer filter life and increased contact time for superior purification compared to standard systems.

Ideal for serious hobbyists with large aquariums, small to medium-sized coral farmers, and local fish stores, the Blue Fin PRO provides an incredible amount of pure water quickly and efficiently. It eliminates the long wait times associated with smaller RO/DI units, making large water changes and daily top-offs effortless. For those with water pressure below 50 PSI or who wish to maximize efficiency, an optional booster pump is available to ensure peak performance.
