Chemistry help please

[doch]

OK, so my KH is reading about 140 ppm (2.8 meg/L, 7.84 dKH). Recommendation is between 125 and 200.

Calcium I'm reading about 390-400. Recommendation is between 380-450ppm.

Should I be happy with these readings, or will my corals benifit from jacking these numbers up to the higher end of the scale?

Just like everybody else out there, I'm looking for ideal growth and colour... any tips are appreciated.

Thanks folks!

PS Phosphates are between .5 and 1 (I'd guess about .75), VERY low nitrates (almost 0) PH at about 8.2ish. Didn't bother with Amonia or Nitrate... they have been next to zero for a while now... haven't started testing Magnesium yet... coming soon.
