HydroLogic® Evolution-RO™ 1000 Membrane Element - 600 GPD - 94%+ TDS Reduction Replacement Membrane

OEM Replacement Membrane for Maximum TDS Reduction

Keep an Evolution-RO™ 1000 or Merlin-Garden Pro™ system running at peak performance with the HydroLogic® Evolution-RO™ 1000 Membrane Element. Rated at 600 GPD and engineered for 94%+ total dissolved solids reduction, this OEM-quality replacement membrane delivers consistent, reliable water purification for growers relying on RO water for precise nutrient management.

Replace membranes when product water output decreases or ppm readings increase above your system's normal baseline — the clearest signs that a membrane has reached the end of its effective service life.

Key Features & Benefits

• 94%+ TDS reduction: consistently removes over 94% of dissolved solids from tap water for precise nutrient solution management.
• Temperature-responsive output: at 77°F, the membrane delivers 100% of rated output; output adjusts proportionally as water temperature rises or falls.
• OEM-quality fitment: designed specifically for Evolution-RO 1000 and Merlin-Garden Pro systems, for guaranteed compatibility and performance.
• Clear replacement indicator: replace when product water volume decreases and/or ppm readings rise above baseline.

Who Should Use This

Essential maintenance component for commercial growers and hydroponic operators running Evolution-RO 1000 or Merlin-Garden Pro systems who want to maintain peak TDS reduction and production flow rates.

Compatibility

Compatible with: HydroLogic Evolution-RO 1000 and Merlin-Garden Pro systems — each system requires two (2) membrane elements. Allow water to run for one hour before collecting product water after installation.

Frequently Asked Questions

How many membranes does the Evolution-RO 1000 require?

The Evolution-RO 1000 and Merlin-Garden Pro systems each require two (2) membrane elements installed together. Installing only one will limit system output well below rated capacity.

When should I replace the membrane?

Replace the membrane when product water output decreases and/or ppm readings increase from your normal operating baseline. Both are early warning signs that TDS rejection has started to decline.

Does water temperature affect membrane output?

Yes — at 77°F the membrane delivers 100% of rated output. Output decreases as water temperature drops and increases as temperature rises, so monitor production volume seasonally.

How long should I flush the system after installing a new membrane?

Allow water to run for one full hour before collecting product water for use after installing a new membrane, to clear preservative solution and settle the membrane into normal operation. Skipping this flush can leave residual storage solution in the initial output water.
