I know this is almost 3 years old, but here I am with the same issue. New setup, not running yet, just trying to get my crap together first.
Incoming TDS is 714ppm with a water pressure of 60psi. I have a 6 stage unit with dual 100g membranes, but was told by the vendor to drop the other membrane and just run a single one as the 2nd membrane will be receiving an even higher concentration of TDS and not be efficient.
I am open to any solution except for moving..sadly moving about 1 mile north would probably drop my TDS to about 100.
