ya I was just wondering at what point does most people change there membranes in there RO/DI systems.
I'm looking for do some replace all there membranes at once or in a certain pattern?
the reason I ask is because I tested or LPS water with my pocket TDS meter and it's running out at 110 and our tap water tests out at 179,I tryed to tell them it's getting high but the manager of the fish department says it's safe up to 128,and I'm looking for some feed back.to take to him because, I think he's wrong?
