Hydro-Logic® Evolution RO1000™ – 1000 GPD Reverse Osmosis System High-performance, commercial-grade water purification. The Evolution RO1000™ produces up to 1,000 gallons per day (GPD) of ultra-pure water—more than 42 gallons per hour—and up to 1,500 GPD with the optional booster pump. This powerful RO system removes 94%+ of total dissolved solids (TDS) and is ideal for serious growers who demand clean, consistent water quality. Key Benefits: Efficient water use – Comes standard with a 2:1 waste-to-product water ratio. Switch to a 1:1 ratio with the included orange flow restrictor to reduce waste (recommended below 300 ppm TDS). Advanced filtration – Custom KDF/catalytic carbon filter removes chlorine, chloramine, iron, sulfur, and heavy metals. Easy to install – Quick setup with color-coded fittings and tubing. Built to last – Durable components and long-lasting membranes with minimal maintenance. For maximum membrane life and lower maintenance, pair it with the Hydro-Logic PreEvolution Pre-Filter (SKU: HGC728792). It’s reusable, high-capacity, and a must-have if you're using over 150 gallons per week. What’s Included: (1) Manifold (3) Filter Housings (1) Carbon Filter (2) 600+ GPD Membranes (1) White Feed Fitting (1) Blue Product Water Fitting (1) Orange 1:1 Drain Fitting (1) Green 2:1 Drain Fitting (1) Lock Bar (1) Pressure Gauge with Tee (1) Support Leg / Housing Wrench Tubing: White (6'), Black (10'), Blue (10') (1) Garden Hose Connector (1) In-line Shut-Off Valve Performance & Compatibility TFC Membrane Rejection Rates (Examples): Calcium: 95–98% Chloride: 92–98% Fluoride: 93–95% Iron: 96–98% Lead: 95–98% Nitrate: 90–95% Sodium: 92–98%(Full chart available in downloadable resources.) Operating Range: Pressure: 40–80 PSI Temp: 40°F–100°F TDS: 50–2,000 mg/L pH: 4–10 Iron: ≤ 0.1 mg/L Chlorine: ≤ 1.0 mg/L Turbidity: ≤ 1 NTU Choosing Between 2:1 and 1:1 Drain Ratios Use the Green 2:1 fitting for longer membrane life. Use the Orange 1:1 fitting to conserve water if your source water is ≤ 300 ppm TDS.Higher TDS with the 1:1 fitting may reduce membrane lifespan.
