i would not change a thing IMO. right now my po4 is closer to .18 and colors look amazing. your no3 is perfect.. when is the last time you changed your membrane and cleaned all the rodi machine?My nitrates are ~32 and phosphates .12.
I'm going to try to pull my phosphates down to your .04-.08 range and see if any colors increase intensity. My plan is to use carbon dosing to do this - which should also reduce nitrates some.
