The AquaFX Whale Shark is a premier seven-stage water purification system designed to produce the absolute purest water for your saltwater reef aquarium. This unit takes tap water and meticulously removes harmful impurities, phosphates, and contaminants, delivering laboratory-grade, 0 TDS water. Hand-built in the USA, it provides the pristine foundation necessary for a thriving and stable marine environment, protecting your most sensitive corals and inhabitants from the dangers of untreated source water.

This system is engineered for maximum efficiency and purity, featuring a premium one-micron sediment filter and two Chlorine Guzzler carbon block filters for robust pre-filtration. The core of the unit is the innovative True 1:1 reverse osmosis membrane, which significantly reduces wastewater compared to traditional systems while maintaining high rejection rates. Following the RO stage, water passes through a unique three-stage deionization process, utilizing separate Cation, Anion, and Mixed-Bed cartridges to capture every last impurity. The Whale Shark also includes a backlit triple TDS meter, an auto shut-off valve, a manual flush kit, and is mounted on a heavy-duty aluminum bracket for durability and convenience.

Ideal for the advanced reef hobbyist and dedicated aquarist, the Whale Shark RO/DI System is for those who refuse to compromise on water quality. Its comprehensive filtration process ensures the complete removal of contaminants that can fuel algae growth and harm delicate corals. The ability to replace individual DI resins makes it a cost-effective choice for serious reef keepers who demand consistent, ultra-pure water to achieve optimal health, growth, and coloration in their high-end reef aquariums.
