HydroLogic® Stealth-RO™ 150 & 350 Membrane Element - 350 GPD - 98%+ TDS Reduction Replacement Membrane

HydroLogic Stealth-RO 150 & 350 Membrane -- 98%+ TDS Reduction

Keep your HydroLogic Stealth-RO 150 or 300 system running at peak performance with the genuine Stealth-RO 150 & 350 Membrane Element. Rated at 350 GPD and delivering 98%+ total dissolved solids (TDS) reduction, this OEM replacement membrane keeps your Stealth-RO system producing purified water for hydroponic nutrient solutions and controlled cultivation applications.

Key Features & Benefits

• 98%+ TDS Reduction: Delivers high-purity starting water for nutrient solution preparation.
• 350 GPD Rated Capacity: Provides the membrane throughput for both Stealth-RO 150 and Stealth-RO 300 system configurations.
• Temperature-Responsive Output: At 77 degrees F the membrane delivers 100% of rated output; output adjusts proportionally as water temperature changes seasonally.
• OEM Fitment: Genuine HydroLogic membrane designed for exact fitment and performance in Stealth-RO systems.

Who Should Use This

Commercial growers, hydroponic operators, and cultivation facilities running Stealth-RO 150 or Stealth-RO 300 systems who want to maintain TDS reduction and system output volume.

Compatibility

Compatible with Stealth-RO 150 and Stealth-RO 300 systems. Replace when product water volume decreases and/or ppm readings increase from baseline. Let water run for one hour before collecting for use after installation.

Frequently Asked Questions

Which systems is this membrane compatible with?

This membrane element is compatible with HydroLogic Stealth-RO 150 and Stealth-RO 300 systems. Confirm your system model before ordering to ensure correct fitment.

When should I replace the membrane?

Replace when product water output volume decreases and/or ppm readings increase from your system's normal operating baseline. Logging your baseline readings after installation makes this drop-off easier to spot.

What TDS reduction does this membrane achieve?

This membrane achieves 98%+ TDS reduction, higher than many RO membranes rated at the standard 94% level. Higher TDS reduction means a cleaner starting point for nutrient solution preparation.

How does water temperature affect output?

At 77 degrees F the membrane delivers 100% of its rated output. Output decreases as water temperature drops and increases as temperature rises, so monitor output and ppm readings seasonally as source water temperature changes.
