Reverse Osmosis

Ensure the best water quality for your reef tank with our reverse osmosis (RO) and deionization (DI) systems, designed to remove harmful contaminants like chlorine, chloramines, nitrates, and phosphates from your tap water. Producing zero total dissolved solids (TDS) water is critical for maintaining the health of your aquarium inhabitants and preventing unwanted algae growth. Our RO and RO/DI systems are engineered to provide the most reliable filtration, ensuring your saltwater aquarium thrives.

We take pride in offering well-built, leak-free systems that are both affordable and durable. With high-quality filters from trusted brands like GE and DOW, and robust dual O-ring push connect fittings, our systems deliver premium performance. Hand-built in Minnesota, our Bulk Reef Supply RO and RO/DI systems come in various configurations to meet your exact needs—whether you're setting up a saltwater aquarium or seeking a reliable drinking water solution.
