The AquaFX 75 GPD RO Membrane is a high-performance replacement component designed to deliver exceptional water purification for your saltwater reef aquarium. This essential membrane utilizes reverse osmosis technology to effectively remove a vast majority of dissolved solids and impurities from tap water, providing the pristine water quality necessary for a thriving marine environment. It serves as a critical barrier in your RO/DI system, ensuring only the purest water enters your mixing station or top-off reservoir.

Engineered with a stabilized salt rejection rate of 98.6%, this AquaFX membrane excels in removing unwanted contaminants, including high silicate levels often problematic for reef tanks. It boasts a production capacity of 75 gallons per day, meaning it can produce 75 gallons of purified water over a 24-hour period. Designed to fit any standard residential membrane housing, it allows for easy upgrades. The membrane operates effectively within a pH range of 2 to 12 and can tolerate short-term temperatures up to 110 degrees Fahrenheit, though it is not chlorine tolerant.

This RO membrane is ideal for reef aquarists seeking to maintain or upgrade their water purification system to ensure the highest water quality for their sensitive corals and fish. By consistently providing ultra-pure water, hobbyists can prevent the introduction of harmful nitrates, phosphates, silicates, and other undesirable elements that can fuel nuisance algae growth and negatively impact coral health. Investing in a high-quality membrane like the AquaFX 75 GPD is a fundamental step towards a successful and vibrant reef aquarium.
