Choosing an RO System for Hard Well Water: Hydro-Logic Merlin Review

Nursery-Tested System

The Hydro-Logic Stealth Merlin Garden Pro RO system (used at Sarracenia Northwest) works well for high-volume production. It removes 95%+ chlorine. For line pressure <40 psi, add a booster pump for efficiency. At 40 psi, TDS ~20 ppm. Membranes last ~2 years. Ideal for continuous use (24/7 in summer).
