SpectraPure 150 GPD RO Membrane
Produce ultra-pure water for your reef tank with the SpectraPure 150 GPD RO Membrane replacement cartridge MEM-0150. This premium drop-in replacement TFC RO membrane for 150 GPD systems is meticulously batch-tested for consistent rejection and production to ensure top-tier performance. It fits standard 2" x 12" RO housings, making it fully compatible with SpectraPure systems and most aquarium and residential RO systems. Featuring a high 98% stabilized salt rejection rate, this reverse osmosis membrane effectively rejects microplastics, PFAS forever chemicals, chlorine, chloramines, heavy metals, and total dissolved solids (TDS). This advanced filtration ensures pristine feed water for delicate corals, marine fish, plants, and families. NOTE: Membrane must be stored in the refrigerator if not being installed immediately to maintain its specialized properties. Remember to pair this item with the correct flow restrictor to prevent water bypass and prevent membrane damage during high-purity water production.

Cleaner water for plants, pets, and people
Reverse osmosis membranes reject microplastics, PFAS and "forever chemicals," chlorine and chloramine byproducts, heavy metals, and the dissolved solids that show up as taste and scale. That means cleaner feed water for your plants, animals, business, or family — and a lot less reliance on bottled water, which keeps plastic out of the landfill. Most setups run a 3:1 waste-to-product ratio on hard water and 2:1 on soft water, and can be tuned to 1:1 in high-purity feed areas or with a periodic pure-water flush. The system is built to last with field-serviceable filter housings, so you replace cartridges (not whole units) for years of dependable purity.
