The AquaFX Whale Shark RO/DI System Chloramine 200GPD is an advanced, 7-stage water purification unit specifically engineered to produce ultra-pure, 0 TDS water for demanding reef aquariums. Hand-built in the USA, this system is designed to effectively remove harmful impurities, phosphates, and chloramines, ensuring the highest quality water for your delicate marine environment. It provides laboratory-grade water, crucial for the health and stability of sensitive reef inhabitants. This robust system features a comprehensive filtration process, beginning with a premium 1-micron sediment filter, followed by two dedicated Chloramine Blaster Carbon filters. The purification continues with AquaFX's True 1:1 RO Membrane, which significantly reduces wastewater while maintaining high rejection properties. Three individual Deionization stages—Cation, Anion, and a Mix-Bed—capture every remaining impurity, allowing for separate resin replacement. Additional features include an ASO (Auto Shut Off) kit, a manual flush kit, a triple TDS meter with a backlit display, quick-disconnect fittings, and a heavy-duty aluminum bracket. The AquaFX Whale Shark is ideally suited for the advanced reef hobbyist who requires uncompromising water quality and efficient chloramine removal. Its multi-stage purification, including the water-saving 1:1 RO membrane and three distinct DI stages, ensures that even the most challenging tap water is transformed into pristine, phosphate-free water. This system is perfect for those seeking to maintain optimal reef conditions, protect their investment in corals and fish, and simplify their water preparation routine with reliable, high-performance equipment.
