GrowMax Water 12" High Flow Membrane (150 GDP) - Compatible with HydroLogic Stealth RO - Case of 25

This 12” High Flow RO Membrane (stored and ships dry) is the replacement membrane for the GrowMax Water Mega Grow 1000, Power Grow 500, and EC Eliminator RO Systems. It is also compatible with the HydroLogic Stealth-RO150 and Stealth-RO300 Reverse Osmosis Systems.

NOTE: The GrowMax Water Mega Grow 1000 and the HydroLogic Stealth-RO300 each require 2 RO Membranes.

Removes up to 95%+ of total dissolved solids (TDS)
Permeate Flow Rate*: up to 150+ GPD (gallons per day), per membrane
*Based on feed water @ 60 psi / 77° / 500 ppm.

PERMEATE FLOW RATE VARIATIONS: Permeate flow rate will vary depending on the temperature of your feed water and the net driving pressure on the membrane element. If your system is running at baseline operating conditions, permeate rate should be at 100% (matching the manufacturer’s listed performance specs). Deviations from these baseline conditions will affect permeate flow rate. As feed water temperature and/or net driving pressure increases or decreases, permeate flow rate will proportionally increase or decrease.

You will need to calculate the adjusted permeate rate to compare or evaluate the performance of your membrane(s) and RO system. This involves calculating Corrected Temperature Permeate Rate and Corrected Net Pressure. Click here for instructions on how to calculate Corrected Temperature Permeate Rate and Corrected Net Pressure. Or use our RO Membrane Flow Rate Calculator to calculate it the fast and easy way.

INSTALLATION INSTRUCTIONS:

Disconnect or turn off the main water supply. Disconnect tubing from the membrane housing end-cap and remove the end-cap by twisting counter-clockwise. There may be some resistance. Use needle-nose pliers or a similar tool to remove the old membrane from the housing. Insert the new membrane into the housing, o-rings first, pushing firmly until the membrane is fully seated. Replace the housing end-cap and reconnect tubing. Flush your RO system for a minimum of 15 minutes when replacing the membrane(s).

REPLACEMENT SCHEDULE:

To keep your membrane in optimum working condition, we recommend replacing every 6 months – 3 years, or upon observing a decrease in flow rate and/or an increase of PPM. The life of your RO membrane(s) is dependent on proper pre-filtration maintenance, feed water quality, and clean water output.
