Take your water purity to the next level with the Dual DI System, designed to seamlessly integrate with any Reefer PRO 4-stage RO/DI unit. This upgrade adds two full-sized mixed-bed deionisation (DI) resin stages, delivering increased capacity, longer resin life, and an extra layer of protection against trace contaminants. Ideal for reef aquariums and high-sensitivity applications, the dual-stage design ensures more consistent 0 TDS water and provides an extra buffer before resin replacement is needed. The system is easy to install with standard ¼” push-fit fittings and includes color-changing resin for quick visual monitoring.
