The Spectrapure Standard 90 GPD Flow Restrictor is a critical component designed to optimize the performance of your reverse osmosis (RO) membrane within an RO/DI system. This device creates the necessary back pressure to ensure the membrane operates at peak efficiency, facilitating the correct waste water to purified water ratio. It is essential for producing the high-quality, ultra-pure water required for a thriving saltwater reef aquarium.

This flow restrictor is specifically calibrated for use with 90 Gallons Per Day (GPD) RO membranes, ensuring a precise and consistent flow rate. Proper flow restriction is vital for maximizing the lifespan of your RO membrane by preventing premature fouling and scaling, while also maintaining optimal contaminant rejection rates. Using the correct GPD-matched flow restrictor is key to the overall efficiency and longevity of your water purification system.

This product is indispensable for reef aquarium enthusiasts who are either setting up a new RO/DI system or performing essential maintenance on an existing one, particularly when replacing or upgrading to a 90 GPD membrane. It guarantees that your RO/DI unit consistently delivers the pure water needed to mix saltwater, top off evaporation, and maintain the delicate chemical balance of your reef tank, directly contributing to the health and vitality of your aquatic inhabitants.
