osmosis

Ok so my water had a PPM of like 325 and after the Reverse Osmosis System it is around 42-50 Should I mess with it some more or be satisfied? I mean I want a 0 ppm but 45 ppm is a heck of a lot better than 325! In this video he takes 320 PPM to 0 wtf???? I have the 200 model which is better...
