You must have had duff merlin membranes or a dodgy tds meter - my own merlin makes water at 5ppm steady, has done for over a year and input was 350ppm until mains was changed or pipes or something, inlet now about 107ppm.

How long does it take you to fill a 1000ltr tank with one of them with a booster pump.
