Review on 💦 Efficient Express Water Reverse Membrane Replacement: Ensuring Pure and Clean Water by Amber Adams

This worked the same as the membrane that came with my Pure-flo II filter. In fact, the original membrane in my Coralife filter was a conventional membrane (CSM from Korea) just like this one. I don't really think there is much of a difference between membranes other than price. After installing Express Water One and other new media, my PPM showed 2-4 PPM with tap water containing around 280 PPM. I recommend this membrane, especially considering the price compared to the "named".
