    yep, that's good! Likely the only way you could get less than that out of RO would be to add a DI stage.. But that is plenty...

    No. Your water is absolutely fine. DI will take it down to zero.. but that's not needed... The harder the water you start with, the harder your water is coming out the RO system (typically) so apparently my water is harder than yours.. mine comes about 9-17ppm. I used that for years and just recently started using DI... Mainly because I don't like the hard water showing up on the g/h walls from the fogger

    So to sum all that up... you're fine and don't need anything else

    2 stage unit? like some type of brita filter or something? Likely it is not going to work. Those removed the chlorine and such, but the TDS (the minerals) won't be removed... That's what the membrane on the RO system does.
