Steve,

yes that helps. Thanks. I am ignorent on this subject. Any and all factual info is appretiated.I have been having some good talks with fellow hobbiest about the quality of different ro membranes.We all seem to go for cheap as possibable in this hobby. With so many different ro membrane I wonder if we sacrifice quality. One freind has perchased a different ro membrane then he ran prior. Now he seems to go though di resins big time. All the different membranes seem to carry different price tags and I would assume different quality. I wonder what the best domestic ro membrane is and whats second and so on.?
