The AquaFX Seahorse RO/DI System 50GPD is a compact and portable reverse osmosis/deionization unit designed to produce ultra-pure, zero TDS water for your saltwater aquarium. Hand-built in the USA, this system efficiently removes a wide range of harmful impurities from municipal tap water, including heavy metals, dissolved solids, chlorine, arsenic, lead, and parasitic cysts, ensuring a clean and safe environment for your delicate reef inhabitants.

This system boasts a high-efficiency 5-micron sediment pre-filter and an inline carbon filter with quick-connect fittings for effortless replacement. It features a high-flow, high-rejection TFC membrane capable of producing 50 gallons per day of purified water, complemented by a high-efficiency, color-indicating translucent DI cartridge with USA Mix-Bed Resin for easy monitoring of resin exhaustion. Its compact size, measuring just 14” x 8” x 6”, along with quick-disconnect fittings, makes installation and storage remarkably simple.

Ideal for hobbyists with smaller aquariums, apartment or condo dwellers, or anyone needing a reliable source of lower daily gallons of ultrapure water, the AquaFX Seahorse RO/DI System is both affordable and exceptionally portable. Its design focuses on ease of use and effective impurity removal, making it a perfect choice for maintaining optimal water quality without taking up excessive space or requiring complex setup.
