At the heart of any RO/DI system is the reverse osmosis membrane which is responsible for removing >99% of the impurities from your source tap water. It is also the component which controls the rate at which the system is able to produce water often expressed as US Gallons Per Day (GPD).
Replacing the RO membrane with a higher capacity membrane is often the easiest way to increase your water production. However, it is not as simple as just swapping out the RO membrane itself. A replacement wastewater flow restrictor is also required to ensure the correct balance and ratio of filtered water to wastewater produced.
This kit contains two 100GPD high-quality thin film composite (TFC) membranes and matched 550mL flow restrictor, which is everything you need to complete the upgrade.
PLEASE NOTE: For single membrane systems such as the Reef Pure RO Systems Essentials and Essentials+ lines, a single Membrane Upgrade Kit is required.
